<h2>New Release Expands to 810 Tools; Gets Major Structured Data Update</h2>
<p>It has been eight months since the last major update to <span style="color: #993300;"><strong><a href="../?page_id=325">Sweet         Tools</a></strong></span>, <span style="color: maroon;"><strong>AI3</strong></span>&#8217;s listing of semantic Web and         -related tools. With today&#8217;s release, there are now a total of         <span style="font-weight: bold;">810 tools listed</span>, crashing         through the <a href="http://en.wikipedia.org/wiki/Sound_barrier">sound         barrier</a> of 761 tools. With the retirement of 19 prior tools, this         new listing represents an increase of 93 tools, or 13%, from the         previous version that listed 736.</p>
<p>But simply adding to the tools listing is not the cause of this longer         than normal period between updates.</p>
<p>This little <span style="color: #993300;"><strong><a href="../?page_id=325">Sweet Tools</a></strong></span> dataset is now showing the way to a couple of exciting         innovations:  new generic <span style="font-style: italic;">ontology-driven applications</span> for         structured data; and, tools for authoring structured data via         spreadsheets.</p>
<p>We deal with the former in this post. I will deal with         the spreadsheet business in a subsequent post.</p>
<h3>Summary of Major Changes</h3>
<p>So, here is the summary of major changes in this new listing:</p>
<ul>
<li> <a href="http://constructscs.com/conStruct/browse/"><img style="border: 1px solid #990000; margin-left: 10px; width: 260px; height: 163px; margin-top: 5px; margin-bottom: 5px; float: right;" title="Sweet Tools conStruct Structured View" src="../wp-content/themes/ai3/images/2009Posts/091007_construct_screen.png" alt="Sweet Tools conStruct Structured View" vspace="5" width="987" height="617" /></a>A completely new structured data view of the listing,           courtesy of <a href="http://structureddynamics.com/">Structured           Dynamics</a>&#8216; <a href="http://openstructs.org/structwsf">structWSF</a> and <a href="http://constructscs.com/">conStruct</a> open source frameworks. This           version can be <a href="http://constructscs.com/conStruct/browse/">viewed on the conStruct           SCS Web site</a> (pick the Sweet Tools dataset). You can compare this           server-side presentation and version to the client-side JavaScript           <a href="../new-version-sweet-tools-sem-web/">version           using Exhibit</a> that has been part of this blog for some time</li>
<li>A new structural organization of the tools into an ontology         that relates portions of the <a href="http://en.wikipedia.org/wiki/ACM_Computing_Classification_System">ACM         classification</a> and  <a href="http://umbel.org/">UMBEL</a> to         the tools categories. This provides richer retrievals and inspections         on the conStruct version (the Exhibit version remains fairly &#8220;flat&#8221; in         structure)</li>
<li>In light of the above, refined tools classifications, and, of         course,</li>
<li>The increase in coverage to 810 tools.</li>
</ul>
<p>To see the major <span style="color: #993300;"><strong><a href="../?page_id=325">Sweet Tools</a></strong></span> page for this updated listing in its existing format, filter on         ‘New’ under <strong>New or Existing?</strong> to see the         recent additions. Alternatively, you can also see this same filtering         using the conStruct structured data view by searching on the Status         attribute using the value &#8216;New&#8217;; see example <a href="http://constructscs.com/conStruct/search/?filter_attributes_4=http%3A%2F%2Fpurl.org%2Fontology%2Fcosmo%23status&amp;query=new&amp;filter=on"> here</a>.</p>
<div class="boxRedSolid" style="margin: 0px 10px 5px 0pt; width: 260px; float: left; font-size: 110%; font-style: italic; text-align: center;">See the new Sweet Tools structured data display at <a href="http://constructscs.com/conStruct/browse/">conStruct</a>!</div>
<h3>Structured Data via conStruct</h3>
<p>Though still formative, the most exciting change with the <a href="http://constructscs.com/conStruct/browse/"><span style="color: #993300;"><strong>Sweet Tools</strong></span></a> listing is         this new presentation via conStruct. It is a structured         data Web services framework with a UI, all offered as a set         of modules to Drupal. To kick the tires with this new system, you may         want to look at:</p>
<ul>
<li> <a href="http://constructscs.com/conStruct/browse/">Browsing the           ontology tree</a> (then, Browse by Kind)</li>
<li>Viewing an <a href="http://constructscs.com/conStruct/view/?uri=http%3A%2F%2Fpurl.org%2Fontology%2Fswt%2Firon&amp;dataset=http%3A%2F%2Fconstructscs.com%2Fwsf%2Fdatasets%2F182%2F"> instance record</a></li>
<li>Viewing a <a href="http://constructscs.com/conStruct/ontology/view/?uri=http%3A%2F%2Fpurl.org%2Fontology%2Fcosmo%23KRBrowser"> Class Type Report</a></li>
<li>Viewing an <a href="http://constructscs.com/conStruct/ontology/view/?uri=http%3A%2F%2Fpurl.org%2Fontology%2Firon%23description"> Attribute Report</a></li>
<li> <a href="http://constructscs.com/conStruct/search/?filter_types_3=http%3A%2F%2Fpurl.org%2Fontology%2Fcosmo%23KRBrowser&amp;filter_attributes_4=http%3A%2F%2Fpurl.org%2Fontology%2Fcosmo%23status&amp;query=new&amp;filter=on"> Searching by facet</a> (check the tabs)</li>
<li>Doing a <a href="http://constructscs.com/conStruct/search/">multi-value filtering</a> (make selections from the various tabs)</li>
<li> <a href="http://constructscs.com/conStruct/export/">Exporting           stuff</a> in a variety of formats.</li>
</ul>
<p>BTW, there are some helpful <a href="http://constructscs.com/documentation/instructions">documentation         pages</a> that show how all of these various tools work and more, such         as, for example, <a href="http://constructscs.com/documentation/instructions/browse">Browse</a>.         (Also, BTW, as a <span style="font-style: italic;">demo</span> user,         you also are not seeing all of the write and update tools, either; again, see the <a href="http://constructscs.com/documentation/instructions">documentation</a>.)</p>
<p>The essential underlying basis to conStruct is the <a href="http://openstructs.org/structwsf">structWSF</a> Web services         framework. There are still some aspects to this system that we feel are         incomplete and we are working on.  Some of these things include         dropdown selections (controlled vocabulary selects); easier template         creation; and intuitive template re-use. Nonetheless, these additions         will come quickly, and what is here is already a great demonstration of         how structured data can drive generic tools and interfaces.</p>
<p>As I said:  More on this in a later post.</p>
<h3>Updated Statistics</h3>
<p>The updated <span style="color: #993300;"><strong><a href="../?page_id=325">Sweet Tools</a></strong></span> listing now includes nearly 50 different tools categories. The most         prevalent categories are browser tools (RDF, OWL), information         extraction, parsers or converters, composite application frameworks and         general ontology tools. Each accounts for more than 8% &#8212; or more than         50 tools &#8212; of the total. This breakdown is as follows (click to         expand):</p>
<div style="margin: 10px 0px;"><a href="../wp-content/themes/ai3/images/2009Posts/091007_swt_applications.png"> <img class="center_ok" style="border: 0px solid; width: 600px; height: 388px;" title="Click to expand" src="../wp-content/themes/ai3/images/2009Posts/091007_swt_applications.png" alt="Sweet Tools Applications" /></a>There are no real discernable trends         in application tool categories over the past couple of years.</div>
<p>As for the languages these applications are written in, that has stayed         pretty steady, too. Java is still the leading language at about 46%,         which has been very slightly trending downward over the past three         years or so. PHP has increased a bit as well. The current splits are         (click to expand):</p>

<h2>Mazzocchi Sounds a Warning to Linked Data Advocates</h2>
<p>Stefano Mazzocchi has been a clear thinker for years and an innovative contributor to the community since his early leadership of the Apache <a href="http://cocoon.apache.org/">Cocoon</a> project. One of his best qualities is he speaks his mind. Now at <a href="http://www.freebase.com/">Freebase</a>, but previously with MIT&#8217;s <a href="http://simile.mit.edu/">Simile</a> program, he is one of my dedicated reads via his <a href="http://www.betaversion.org/~stefano/linotype/">Stefano’s Linotype</a> blog.</p>
<p>His aforementioned post, <em><a href="http://www.betaversion.org/~stefano/linotype/news/351/">Data Smoke and Mirrors</a></em>, stands on its own, and I highly recommend it. He particularly focuses on the conversion of <a href="http://data.gov/">data.gov</a> datasets to &#8220;<a href="http://structureddynamics.com/linked_data.html">linked data</a>&#8221; (my quotes are purposeful). Combined with the recent poor conversion of <a href="http://open.blogs.nytimes.com/2009/10/29/first-5000-tags-released-to-the-linked-data-cloud/">New York Times datasets</a> to linked data, I think he is the canary sending out a warning about a disturbing trend.</p>
<p>Posting linked data for its own sake &#8212; whatever the reasons &#8212; risks undercutting the premise.</p>
<p>We have now moved beyond &#8220;proof of concept&#8221; to the need for actual useful data of trustworthy provenance and proper mapping and characterization. Recent efforts are a disappointment that no enterprise would or could rely upon.</p>
<p>Listen up, folks.</p>

<h2>New Cross-Scripting Frameworks for XML, JSON and Spreadsheets</h2>
<p>On behalf of <a href="http://structureddynamics.com/">Structured         Dynamics</a>, I am pleased to announce our release into the open source         community of <span style="font-style: italic; font-weight: bold;">irON</span> — the         <span style="font-style: italic;">instance record</span> and         <span style="font-style: italic;">Object Notation</span> — and         its family of frameworks and tools <a href="#ia1">[1]</a>. With <span style="font-weight: bold; font-style: italic;">irON</span>, you can now         author and conduct business solely in the formats and tools most         familiar and comfortable to you, all the while enabling your data to         interact with the semantic Web.</p>
<p><span style="font-weight: bold; font-style: italic;">irON</span> is an         abstract notation and associated vocabulary for specifying RDF triples         and schema in non-RDF forms. Its purpose is to allow users and tools in         non-RDF formats to stage interoperable datasets using RDF. The notation         supports writing RDF and schema in <a href="http://en.wikipedia.org/wiki/JSON">JSON</a> (<span style="font-weight: bold; font-style: italic;">irJSON</span>), <a href="http://en.wikipedia.org/wiki/Xml">XML</a> (<span style="font-weight: bold; font-style: italic;">irXML</span>) and         comma-delimited (<a href="http://en.wikipedia.org/wiki/Comma-separated_values">CSV</a>) formats         (<span style="font-weight: bold; font-style: italic;">commON</span>).</p>
<p>The surprising thing about <span style="font-weight: bold; font-style: italic;">irON</span> is that — by         following its simple conventions and vocabulary — you will be         authoring and creating interoperable RDF datasets without doing much         different than your normal practice.</p>
<p>This first specification for the <a href="http://openstructs.org/iron/iron-specification"><span style="font-weight: bold; font-style: italic;">irON</span> notation</a> includes guidance for creating instance records         (including in bulk), linkages to existing ontologies and schema, and         schema definitions. In this newly published <a href="http://openstructs.org/iron/iron-specification"><span style="font-weight: bold; font-style: italic;">irON</span> specificatiion</a>, profiles and examples are also provided for each of         the <span style="font-weight: bold; font-style: italic;">irXML</span>,         <span style="font-weight: bold; font-style: italic;">irJSON</span> and         <span style="font-weight: bold; font-style: italic;">commON</span> serializations. The <span style="font-weight: bold; font-style: italic;">irON</span> release also         includes a number of parsers and converters of the specification into         RDF <a href="#ia2">[2]</a>. Data ingested in the <span style="font-weight: bold; font-style: italic;">irON</span> frameworks can         also be exported as RDF and staged as <a href="http://en.wikipedia.org/wiki/Linked_data">linked data</a>.</p>
<div class="boxRedDotted"><strong>UPDATE</strong>: Fred Giasson <a href="http://fgiasson.com/blog/index.php/2009/10/20/common-and-irjson-php-parsers-released/">announced</a> on his blog today (10/20) the release of the <em><strong>irJSON </strong></em>and <em><strong>commON</strong></em> parsers.</div>
<h3>Background and Rationale</h3>
<p>The objective of <span style="font-weight: bold; font-style: italic;">irON</span> is to make it easy         for data owners to author, read and publish data. This means the         starting format should be a human readable, easily writable means for         authoring and conveying instance records (that is, instances and their         attributes and assigned values) and the datasets that contain them.         Among other things, this means that <span style="font-style: italic; font-weight: bold;">irON</span>&#8217;s notation does         not use RDF &#8220;<a href="http://en.wikipedia.org/wiki/Resource_Description_Framework">triples</a>&#8220;,         but rather the native notations of the host serializations.</p>
<p><span style="font-weight: bold; font-style: italic;">irON</span> is         premised on these considerations and observations:</p>
<ul>
<li> <a href="http://en.wikipedia.org/wiki/Resource_Description_Framework">RDF</a> (Resource Description Framework) is a powerful canonical data model           for data interoperability <a href="#ia3">[3]</a></li>
<li>However, most existing data is not written in RDF and many authors         and publishers prefer other formats for various reasons</li>
<li>Many formats that are easier to author and read than RDF are         variants of the attribute-value pair construct <a href="#ia4">[4]</a>, which can readily         be expressed as RDF, and</li>
<li>A common abstract notation for converting to RDF would also enable         non-RDF formats to become somewhat interchangeable, thus allowing the         strengths of each to be combined.</li>
</ul>
<p>The <span style="font-weight: bold; font-style: italic;">irON</span> notation and vocabulary is designed to allow the conceptual structure         (&#8221;schema&#8221;) of datasets to be described, to facilitate easy description         of the instance records that populate those datasets, and to link         different structures for different schema to one another. In these         manners, more-or-less complete RDF data structures and instances can be         described in alternate formats and be made interoperable. <span style="font-weight: bold; font-style: italic;">irON</span> provides a simple         and naïve information exchange notation expressive enough to describe         most any data entity.</p>
<p>The notation also provides a framework for extending existing schema.         This means that <span style="font-weight: bold; font-style: italic;">irON</span> and its three         serializations can represent many existing, common data formats and         standards, while also providing a vehicle for extending them. Another         intent of the specification is to be sparse in terms of requirements.         For instance, this reserved vocabulary is fairly minimal and optional         in most all cases. The <span style="font-weight: bold; font-style: italic;">irON</span> specification         supports skeletal submissions.</p>
<h3>irON Concepts and Vocabulary</h3>
<p>The aim of <span style="font-weight: bold; font-style: italic;">irON</span> is to describe         instance <span style="font-style: italic;">records</span>. An instance         record is simply a means to represent and convey the information         (”attributes”) describing a given instance. An instance is         the thing at hand, and need not represent an individual; it could, for         example, represent the entire holdings or collection of books in a         given library. Such instance records are also known as the         <em>ABox</em> <a href="#ia5">[5]</a>. The simple design of <span style="font-weight: bold; font-style: italic;">irON</span> is in keeping with         the limited roles and work associated with this <span style="font-style: italic;">ABox</span> role.</p>
<p><span style="font-style: italic;">Attributes</span> provide descriptive         characteristics for each instance. Every attribute is matched with a         value, which can range from descriptive text strings to lists or         numeric values. This design is in keeping with simple attribute-value         pairs where, in using the terminology of RDF triples, the         <em>subject</em> is the instance itself, the <em>predicate</em> is the         attribute, and the <em>object</em> is the value. <span style="font-weight: bold; font-style: italic;">irON</span> has a vocabulary         of about 40 reserved attribute terms, though only two are ever         required, with a few others strongly recommended for interoperability         and interface rendering purposes.</p>
<p>A <span style="font-style: italic;">dataset</span> is an aggregation of         instance records used to keep a reference between the instance records         and their source (provenance). It is also the container for         transmitting those records and providing any metadata descriptions         desired. A dataset can be split into multiple dataset slices. Each         slice is written to a file serialized in some way. Each slice of a         dataset shares the same <span style="font-family: Courier New,Courier,monospace;">&lt;id&gt;</span> of the         dataset.</p>
<p>Instances can also be assigned to <span style="font-style: italic;">types</span>, which provide the set or         classificatory structure for how to relate certain kinds of things         (instances) to other kinds of things. The organizational relationships         of these types and attributes is described in a <span style="font-style: italic;">schema</span>. <span style="font-weight: bold; font-style: italic;">irON</span> also has         conventions and notations for describing the <span style="font-style: italic;">linkage</span> of attributes and types in a given         dataset to existing schema. These linkages are often mapped to         established ontologies.</p>
<p>Each of these <span style="font-weight: bold; font-style: italic;">irON</span> concepts of         <span style="font-style: italic;">records</span>, <span style="font-style: italic;">attributes</span>, <span style="font-style: italic;">types</span>, <span style="font-style: italic;">datasets</span>, <span style="font-style: italic;">schema</span> and <span style="font-style: italic;">linkages</span> share similar notations with         keywords signaling to the <span style="font-weight: bold; font-style: italic;">irON</span> parsers and         converters how to interpret incoming files and data. There are also         provisions for metadata, name spaces, and local and global references.</p>
<p>In these manners, <span style="font-weight: bold; font-style: italic;">irON</span> and its three         serializations can capture virtually the entire scope and power of RDF         as a data model, but with simpler and familiar terminology and         constructs expected for each serialization.</p>
<h3>The Three Serializations</h3>
<p>For different reasons and for different audiences, the formats of XML,         JSON and CSV (spreadsheets) were chosen as the representative formats         across which to formulate the abstract <span style="font-weight: bold; font-style: italic;">irON</span> notation.</p>
<p><a href="http://en.wikipedia.org/wiki/Xml">XML</a>, or eXtensible         Markup Language, has become the leading data exchange format and syntax         for modern applications. It is frequently adopted by industry groups         for standards and standard exchange formats. There is a rich diversity         of tools that support the language, importantly including capable         parsers and query languages. There is also a serialization of RDF in         XML. As implemented in the <span style="font-weight: bold; font-style: italic;">irON</span> notation, we call         this serialization <span style="font-weight: bold; font-style: italic;">irXML</span>.</p>
<p><a href="http://en.wikipedia.org/wiki/JSON">JSON</a>, the JavaScript         Object Notation, has become very popular as a Web 2.0 data exchange         format and is often the format of choice to drive JavaScript         applications. There is a growing richness of tools that support JSON,         including support from leading Web and general scripting languages such         as JavaScript, Python, Perl, Ruby and PHP. JSON is relatively easy to         read, and is also now growing in popularity with lightweight databases,         such as CouchDB. As implemented in the <span style="font-weight: bold; font-style: italic;">irON</span> notation, we call         this serialization <span style="font-weight: bold; font-style: italic;">irJSON</span>.</p>
<p><a href="http://en.wikipedia.org/wiki/Comma-separated_values">CSV</a>,         or comma-separated values, is a format that has been in existence for         decades. It was made famous by Microsoft as a spreadsheet exchange         format, which makes CSV very useful since spreadsheets are the most         prevalent data authoring environment in existence. CSV is less         expressive and capable as a data format than the other <span style="font-weight: bold; font-style: italic;">irON</span> serializations,         yet still has a attribute-value pair orientation. And, via         spreadsheets, datasets can be easily authored and inspected, while also         providing a rich functional environment including sorting, formatting,         data validation, calculations, macros, etc. As implemented in the         <span style="font-weight: bold; font-style: italic;">irON</span> notation, we call this serialization <span style="font-weight: bold; font-style: italic;">commON</span>.</p>
<p>The following diagram shows how these three formats relate to         <span style="font-weight: bold; font-style: italic;">irON</span> and         then the canonical RDF target data model:</p>
<div><img class="center_ok" style="width: 547px; height: 619px;" title="Data transformations path" src="../wp-content/themes/ai3/images/2009Posts/data_transform_path.png" alt="Data transformations path" width="547" height="619" /></div>
<p>We have used the unique differences amongst XML, JSON and CSV to guide         the embracing abstract notations within <span style="font-weight: bold; font-style: italic;">irON</span>. Note the         round-tripping implications of the framework.</p>
<p>One exciting prospect for the design is how, merely by following the         simple conventions within <span style="font-weight: bold; font-style: italic;">irON</span>, each of these         three data formats — and RDF !! — can be used more-or-less         interchangeably, and can be used to extend existing schema within their         domains.</p>

<h3>Editors&#8217; Notes</h3>
<p><span style="font-weight: bold; font-style: italic;">irON</span> is an         important piece in the semantic enterprise puzzle that we are building         at <a href="http://structureddynamics.com/">Structured Dynamics</a>. It         reflects our belief that knowledge workers should be able to author and         create interoperable datasets without having to learn the arcana of         RDF. At the same time we also believe that RDF is the appropriate data         model for interoperability. <span style="font-weight: bold; font-style: italic;">irOn</span> is an expression         of our belief that many data formats have appropriate places and uses;         there is no need to insist on a single format.</p>
<p>We would like to thank <a href="http://www.stat.berkeley.edu/%7Epitman/">Dr. Jim Pitman</a> for his         advocacy of the importance of human-readable and easily authored         datasets and formats. Via his leadership of the Bibliographic Knowledge         Network (BKN) project and our contractual relationship with it <a href="#ia7">[7]</a>, we         have learned much regarding the BKN&#8217;s own format, BibJSON.

<div style="margin: 10px 0pt; font-size: 90%;"><a id="ia3" name="ia3"></a> [3] A pivotal premise of <span style="font-weight: bold; font-style: italic;">irON</span> is the         desirability of using the RDF data model as the canonical basis for         interoperable data. RDF provides a data model capable of representing         any extant data structure and any extant data format. This flexibility         makes RDF a perfect data model for federating across disparate data         sources. For a detailed discussion of RDF, see Michael K. Bergman,         2009. &#8220;Advantages and Myths of RDF,&#8221; in <span style="font-style: italic;">AI3 blog</span>, April 8, 2009. See <a href="../483/advantages-and-myths-of-rdf/">http://www.mkbergman.com/483/advantages-and-myths-of-rdf/</a>.</div>

Each table cell         therefore designates the value (also known as <span style="font-style: italic;">state</span>) of a particular attribute of a         particular object. This is the basic table presentation of a         spreadsheet or relational data table.</p>
<p>Attribute-values can also be presented as pairs in the form of an         <a href="http://en.wikipedia.org/wiki/Associative_array">associative         array</a>, where the first item listed is the attribute, often followed         by a separator such as the colon, and then the value. JSON and many         simple data struct notations follow this format. This format may also         be called <span style="font-style: italic;">attribute-value         pairs</span>, <span style="font-style: italic;">key-value pairs</span>,         <span style="font-style: italic;">name-value pairs</span>, <span style="font-style: italic;">alists</span> or others. In these cases the         &#8220;object&#8221; is implied, or is introduced as the name of the array.</div>

<h2>A Marshal to Bring Order to the Town of Data Gulch</h2>
<p>Though not the first, I have been touting the <span style="font-weight: bold; font-style: italic;">Linked Data Law</span> for a         couple of years now <a href="#ldl_1">[1]</a>. But in a conversation last week, I found that         my colleague did not find the premise very clear. I suspect that is due         both to cryptic language on my part and the fact no one has really         tackled the topic with focus. So, in this post, I try to redress that         and also comment on the related role of linked data in the semantic         enterprise.</p>
<p>Adding connections to existing information via linked data is a         powerful force multiplier, similar to <a href="http://en.wikipedia.org/wiki/Metcalf%27s_law">Metcalfe&#8217;s law</a> for         how the value of a network increases with more users (nodes). I have         come to call this the <span style="font-weight: bold; font-style: italic;">Linked Data Law</span>: the         value of a linked data network is proportional to the square of the         number of links between data objects.</p>
<div class="boxGreenDotted" style="margin: 5px 0pt 5px 0px; float: right; text-align: center; width: 360px;"><big style="font-style: italic; color: #006600; font-weight: bold;">&#8220;In the       network economy, the connections are as important as the nodes.&#8221;</big> <a href="#ldl_2">[2]</a></div>
<p>An early direct mention of the semantic Web and its possible ability to         generate <a href="http://en.wikipedia.org/wiki/Network_effect">network         effects</a> comes from a 2003 Mitre report for the government <a href="#ldl_3">[3]</a>. In         it, the authors state, &#8220;At present a very small proportion of the data         exposed on the web is marked up using Semantic Web vocabularies like         RDF and OWL. As more data gets mapped to ontologies, the potential         exists to achieve a &#8216;network effect&#8217;.&#8221; Prescient, for sure.</p>
<p>In July 2006, both Henry Story and Dion Hinchliffe discussed Metcalfe&#8217;s         law, with Henry specifically looking to relate it to the semantic Web <a href="#ldl_4"> [4]</a>. He noted that his initial intuition was that &#8220;the value of your         information grows exponentially with your ability to combine it with         new information.&#8221; He noted he was trying to find ways to adapt         Metcalfe&#8217;s law for applicability to the semantic Web.</p>
<p>I picked up on those observations and commented to Henry at that time         and in my own post, &#8220;<a style="font-style: italic;" title="Permanent Link to The Exponential Driver of Combining Information" rel="bookmark" href="../255/the-exponential-driver-of-combining-information/">The         Exponential Driver of Combining Information</a>.&#8221; I have been enamoured         of the idea ever since, and have begun to weave the idea into my         writings.</p>
<p>More recently, in late 2008, James Hendler and Jennifer Golbeck devoted         an entire paper to Metcalfe&#8217;s law and the semantic Web <a href="#ldl_5">[5]</a>. In it, they         note:</p>
<p style="margin-left: 40px;">&#8220;This linking between ontologies, and between instances in documents         that refer to terms in another ontology, is where much of the latent         value of the Semantic Web lies. The vocabularies, and particularly         linked vocabularies using URIs, of the Semantic Web create a graph         space with the ability to link any term to any other. As this link         space grows with the use of RDF and OWL, Metcalfe&#8217;s law will once again         be exploited – the more terms to link to, and the more links         created, the more value in creating more terms and linking them in.&#8221;</p>
<h3>A Refresher on Metcalfe&#8217;s Law</h3>
<p><a href="http://en.wikipedia.org/wiki/Metcalf%27s_law">Metcalfe’s         law</a> states that the value of a telecommunications network is         proportional to the square of the number of users of the system         (<span style="font-style: italic;">n</span>²) (note: it is <span style="font-weight: bold; font-style: italic;">not</span> exponential, as         some of the points above imply). <a href="http://en.wikipedia.org/wiki/Robert_Metcalfe">Robert Metcalfe</a> formulated it about 1980 in relation to Ethernet and fax machines; the         &#8220;law&#8221; was then named for Metcalfe and popularized by <a href="http://en.wikipedia.org/wiki/George_Gilder">George Gilder</a> in 1993.</p>
<p>These attempts to estimate the value of physical networks were in         keeping with earlier efforts to estimate the value of a broadcast         network. That value is almost universally agreed to be proportional to         the number of users, as accepted as <a href="http://en.wikipedia.org/wiki/Sarnoff%27s_law">Sarnoff&#8217;s law</a> (see         further below).</p>
<p>The actual algorithm proposed by Metcalfe calculates the number of         unique connections in a network with <span style="font-style: italic;">n</span> nodes to be <em>n</em>(<em>n</em> −         1)/2, which is proportional to <em>n</em><sup>2</sup>. This makes         Metcalfe&#8217;s law a quadratic growth equation.</p>
<p>As nodes get added, then, we see the following increase in connections:</p>
<div style="margin: 5px 0pt;"><a href="../wp-content/themes/ai3/images/2009Posts/091011_telephone.png"> <img class="center_ok" style="border: 0px solid; width: 600px; height: 180px;" title="Click to enlarge" src="../wp-content/themes/ai3/images/2009Posts/091011_telephone.png" alt="Metcalfe Law Network Effect" hspace="5" /></a></p>
<h5 style="color: #820000;">&#8216;Network Effect&#8217; for Physical Networks</h5>
</div>
<p>This diagram, modified from <a href="http://en.wikipedia.org/wiki/File:Network_effect.png">Wikipedia</a> to         be a horizontal image, shows how two telephones can make only one         connection, five can make 10 connections, and twelve can make 66         connections, etc.</p>
<p>By definition, a physical network is a connected network. Thus, every         time a new node is added to the network, connections are added, too.         This general formula has also been embraced as a way to discuss social         connections on the Internet <a href="#ldl_6">[6]</a>.</p>
<h3>Analogies to Linked Data</h3>
<p>Like physical networks, the interconnectedness of the semantic Web or         semantic enterprise is a graph.</p>
<p>The idea behind <a href="http://structureddynamics.com/linked_data.html">linked data</a> is to         make connections between data. Unlike physical telecommunication         networks, however, the nodes in the form of datasets and data are         (largely) already there. What is missing are the connections. The         build-out and growth that produces the <a href="http://en.wikipedia.org/wiki/Network_effect">network effects</a> in a         linked data context do not result from adding more nodes, but from the         linking or connecting of <span style="font-weight: bold; font-style: italic; text-decoration: underline;">existing</span> nodes.</p>
<p>The fact that adding a node to a physical network carries with it an         associated connection has tended to conjoin these two complementary         requirements of node <span style="font-weight: bold; font-style: italic;">and</span> connection. But, to         grok the real dynamics and to gain network effects, we need to realize:         Both nodes and connections are necessary.</p>
<p>One circumstance of the enterprise is that data nodes are everywhere.         The fact that the overwhelming majority are unconnected is why we have         adopted the popular colloquialism of data &#8220;silos&#8221;. There are also         massive amounts of unconnected data on the Web in the form of dynamic         databases only accessible via search form, and isolated data tables and         listings virtually everywhere.</p>
<p>Thus, the essence of the <span style="font-style: italic;">semantic         enterprise</span> and the <span style="font-style: italic;">semantic         Web</span> is no more complicated than connecting — <span class="double_u">meaningfully</span> — data nodes that already exist.</p>
<p>As the following diagram shows, unconnected data nodes or silos look         like random particles caught in the chaos of <a href="http://en.wikipedia.org/wiki/Brownian_motion">Brownian motion</a>:</p>
<div style="margin: 5px 0pt;"><a href="../wp-content/themes/ai3/images/2009Posts/091011_network.png"> <img class="center_ok" style="border: 0px solid; width: 600px; height: 196px;" title="Click to enlarge" src="../wp-content/themes/ai3/images/2009Posts/091011_network.png" alt="Linked Data Law Network Effect" hspace="5" /></a></p>
<h5 style="color: #820000;">&#8216;Network Effect&#8217; for Coherent Linked Data</h5>
</div>
<p>As initial connections get made, bits of structure begin to emerge.         But, as connections are proliferated — <span style="font-weight: bold; font-style: italic;">exactly</span> equivalant to         the network effects of connected networks — coherence and value         emerge.</p>
<p>Look at the last part in the series diagram above. We not only see that         the same nodes are now all connected, with the inferences and         relationships that result from those connections, but we can also see         entirely new structures emerge by virtue of those connections. All of         this structure and meaning was totally absent prior to making the         linked data connections.</p>
<h3>Quantifying the Network Effect</h3>
<p>So, what is the benefit of this linked data? It depends on the product         of the <span style="font-style: italic;">value</span> of the         connections and the <span style="font-style: italic;">multiplier</span> of the network effect:</p>
<div style="margin: 10px 0pt; text-align: center;">linked data benefit <span style="font-weight: bold; font-family: Arial Black;">=</span> connections         <span style="font-style: italic;">value</span> <span style="font-weight: bold;">X</span> network effect <span style="font-style: italic;">multiplier</span></div>
<p>Just as it is hard to have a conversation via phone with yourself, or         to collaborate with yourself, the ability to gain perspective and         context from data comes from connections. But like some phone calls or         some collaborations, the <span style="font-style: italic;">value</span> depends on the participants. In the case of linked data, that depends         on the quality of the data and its <span style="font-style: italic; font-weight: bold;">coherence</span> <a href="#ldl_7">[7]</a>. The         value &#8220;constant&#8221; for connected linked data depends in some manner on         these factors, as well as the purposes and circumstances to which that         linked data might be applied.</p>
<p>Even in physical networks or social collaboration contexts, the &#8220;value&#8221;         of the network has been hard to quantify. And, while academics and         researchers will appropriately and naturally call for more research on         these questions, we do not need to be so timid. Whatever the         <span style="font-style: italic;">alpha</span> constant is for         quantifying the value of a linked data network, our intuition should be         clear that making connections, finding relationships, making         inferences, and making discoveries can not occur when data is in         isolation.</p>
<p>Because I am an advocate, I believe this <span style="font-style: italic;">alpha</span> constant of value to be quite large.         I believe this constant is also higher for circumstances of business         intelligence, knowledge management and discovery.</p>
<p>The second part of the benefit equation is the <span style="font-style: italic;">multiplier</span> for network effects. We&#8217;ve         mentioned before the linear growth advantage due to broadcast networks         (Sarnoff law) and the standard quadratic growth assumption of physical         and social networks (Metcalfe law). Naturally, there have been other         estimates and advocacies.</p>
<p>David Reed <a href="#ldl_8">[8]</a>, for example, also adds group effects and has asserted         an exponential multiplier to the network effect (like Henry Story&#8217;s         initial intuition noted above). As he states,</p>
<p style="margin-left: 40px;">&#8220;[E]ven Metcalfe&#8217;s Law understates the value created by a group-forming         network [GFN] as it grows. Let&#8217;s say you have a GFN with <span style="font-style: italic;">n</span> members. If you add up all the potential         two-person groups, three-person groups, and so on that those members         could form, the number of possible groups equals <span>2<sup><em>n</em></sup></span>. So the value of a GFN increases         exponentially, in proportion to <span>2<sup><em>n</em></sup></span>. I call that Reed&#8217;s Law. And its         implications are profound.&#8221;</p>
<p>Yet not all agree with the assertion of an exponential multiplier, let         alone the quadratic one of Metcalfe. Odlyzko and Tilly <a href="#ldl_9">[9]</a> note that         Metcalfe&#8217;s law would hold if the value that an individual gets         personally from a network is directly proportional to the number of         people in that network. But, then they argue that does not hold because         of local preferences or different qualities of interaction. In a linked         data context, such arguments have merit, though you may also want to         see Metcalfe&#8217;s own counter-arguments <a href="#ldl_6">[6]</a>.</p>
<p>Hinchliffe&#8217;s earlier commentary <a href="#ldl_4">[4]</a> provided a nice graphic that shows         the implications of these various multiplers on the network effect, as         a function of nodes in a network:</p>
<div style="margin: 5px 0pt; text-align: center;"><img class="center_ok" style="border: 0px solid; width: 528px; height: 329px;" src="../wp-content/themes/ai3/images/2009Posts/091011_network_effects.jpg" alt="Potency of the Network Effect from Dion Hinchliffe" hspace="5" width="528" height="329" /></p>
<h5 style="color: #820000;">Various Estimates for the &#8216;Network Effect&#8217;</h5>
</div>
<p>I believe we can dismiss the lower linear bound of this question and         likely the higher exponential one as well (that is, Reed&#8217;s law, because         quality and relevance questions make some linked data connections less         valuable than others). Per the above, that would suggest that the         <span style="font-style: italic;">multiplier</span> of the linked data         network is perhaps closer to the Metcalfe estimate or similar.</p>
<p>In any event, it is also essential to point out that connecting data         indiscriminantly for linked data&#8217;s sake will likely deliver few, if         any, benefits. Connections must still be coherent and logical for the         value benefits to be realized.</p>
<h3>The Role and Contribution of Linked Data</h3>
<p>I <a href="../825/fresh-perspectives-on-the-semantic-enterprise/"> elsewhere</a> discuss the role of linked data in the enterprise and         will continue to do so. But, there are some implications in the above         that warrant some further observations.</p>
<p>It should be clear that the graph and network basis of linked data, not         to mention some of the uncertainties as to quantifying benefits,         suggests the practice should be considered apart from mission-critical         or transactional uses in the enterprise. That may change with time and         experience.</p>
<p>There are also open questions about data quality in terms of inputs to         linked data and possible erroneous semantics and ontologies to guide         the linked connections. Operational uses should be kept off the table         for now. Like physical networks, not all links perform well and not all         have usefulness. Similarly to how poor connections may be encountered         in physical networks, they should be either taken off-ledger or         relegated to a back-up basis. Linked data should be understood and         treated no differently than networks of variable quality.</p>
<p>Such realism is important — for both internal and external linked         data advocates — to allow linked data to be applied in the right         venues at acceptable risk and with likely demonstrable benefits.         <a href="../553/confronting-misconceptions-with-adaptive-ontologies/"> Elsewhere</a> I have advocated an approach that builds on existing         assets; here I advocate a clear and smart understanding of where linked         data can best deliver network effects in the near term.</p>
<p>And, so, in the nearest term, enterprise applications that best fit         linked data promises and uncertainties include:</p>
<ul>
<li>Establishing frameworks for data federation</li>
<li>Business intelligence</li>
<li>Discovery</li>
<li>Knowledge management and knowledge resources</li>
<li>Reasoning and inference</li>
<li>Development of internal common language</li>
<li>Learning and adopting data-driven apps <a href="#ldl_10">[10]</a>, and</li>
<li>Staging and analysis for data cleaning.</li>
</ul>
<h3>A New Deputy Has Come to Town</h3>
<p>As in the Wild West, the new deputy marshal and his tin badge did not         guarantee prosperity. But a good marshal would deliver law and order.         And those are the preconditions for the town folk to take charge of         building their own prosperity.</p>
<p>Linked data is a practice for starting to bring order and connections         to your existing data. Once some order has been imposed, the framework         then becomes a basis for defining meanings and then gaining value from         those connections.</p>
<p>Once order has been gained, it is up to the good citizens of Data Gulch         to then deliver the prosperity. Broad participation and the network         effect are one way to promote that aim. But success and prosperity         still depends on intelligence and good policies and practice.</p>

<h2><img style="margin-right: 10px; margin-bottom: 10px;" title="Teeny Head" src="http://www.mkbergman.com/wp-content/themes/ai3/images/2009Posts/091009_teeny_head.png" alt="Pinhead Baby" align="left" /><span style="color: #820000;"><strong>Pinheads Sometimes Get the Last Laugh</strong></span></h2>
<p>The idea of the <a title="'Long Tail'" href="http://en.wikipedia.org/wiki/The_Long_Tail">&#8216;long tail&#8217;</a> was brilliant, and Chris Anderson&#8217;s meme has become part of our current lingo in record time.<em> </em>The<em> long tail</em> is the colloquial name for a common feature in some statistical distributions where an initial high-amplitude peak within a population distribution is followed by a rapid decline and then a relatively stable, declining low-amplitude population that &#8220;tails off.&#8221; (An asymptotic curve.) This sounds fancy; it really is not. It simply means that a very few things are very popular or topical, most everything else is not.</p>
<p>The following graph is a typical depiction of such a statistical distribution with the long tail shown in yellow. Such distributions often go by the names of <a title="Power law" href="http://en.wikipedia.org/wiki/Power_law">power laws</a>, <a title="Zipf's law" href="http://en.wikipedia.org/wiki/Zipf%27s_law">Zipf distributions</a>, <a title="Pareto distribution" href="http://en.wikipedia.org/wiki/Pareto_distribution">Pareto distributions</a> or <a title="Lévy skew alpha-stable distribution" href="http://en.wikipedia.org/wiki/L%C3%A9vy_skew_alpha-stable_distribution">general Lévy distributions</a>. (Generally, such curves when plotted on a semi-logarithmic scale now show the curve to be straight, with the slope being an expression of its &#8220;power&#8221;.)<a href="http://upload.wikimedia.org/wikipedia/commons/8/8a/Long_tail.svg"><img style="border: 0pt none;" src="http://www.mkbergman.com/wp-content/themes/ai3/images/2009Posts/091009_teeny_heads_long_tails.png" border="0" alt="Image:Long tail.svg" width="336" height="175" align="left" /></a></p>
<p>It is a common observation that virtually everything measurable on the Internet &#8212; site popularity, site traffic, ad revenues, tag frequencies on <a title="del.icio.us" href="http://del.icio.us/">del.icio.us</a>, open source downloads by title, Web sites chosen to be <a title="digg.com" href="http://digg.com/">digg</a>&#8216;ed, Google search terms &#8212; follows such power laws or curves.</p>
<p>However, the real argument that Anderson made first in <a title="Wired Magazine" href="http://www.wired.com/"><em>Wired</em></a> magazine and then in his 2006 book, <a title="The Long Tail: Why the Future of Business is Selling Less of More" href="http://www.amazon.com/Long-Tail-Future-Business-Selling/dp/1401302378"><em>The Long Tail: Why the Future of Business is Selling Less of More</em></a>, is that the Internet with either electronic or distributed fulfillment means that the cumulative provision of items in the long tail is now enabling the economics of some companies to move from &#8220;mass&#8221; commodities to &#8220;specialized&#8221; desires. Or, more simply put: There is money to be made in catering to individualized tastes.</p>
<p>I, too, agree with this argument, and it is a brilliant recognition of the fact that the Internet changes everything.</p>
<h3><strong>But Long Tails Have &#8216;Teeny Heads&#8217;</strong></h3>
<p>Yet what is amazing about this observation of long tails on the Internet has been the total lack of discussion of its natural reciprocal: namely, <em>long tails</em> have <strong><em>teeny heads</em></strong>, the red portion of the diagram. For, after all, what also is the curve above telling us? While Anderson&#8217;s point that Amazon can carry millions of book titles and still make a profit by only selling a few of each, what is going on at the <em>other end of the curve</em> &#8212; the <em><strong>head end</strong></em> of the curve?</p>
<p>Well, if we&#8217;re thinking about book sales, we can make the natural and expected observation that the head end of the curve represents sales of the best seller books; that is, all of those things in the old 80-20 world that is now being blown away with the long tail economics of the Internet. Given today&#8217;s understandings, this observation is pretty prosaic since it forms the basis of Anderson&#8217;s new <em>long tail</em> argument.  Pre-Internet limits (it&#8217;s almost like saying <em>before the Industrial Revolution</em>) kept diversity low and choices few.</p>
<p><em>Okaaaay!</em> Now that seems to make sense.  But aren&#8217;t we <span style="text-decoration: underline;"><em>still</em></span> missing something?  Indeed we are.</p>
<h3><strong>Social Collaboration Depends on &#8216;Teeny Heads&#8217;</strong></h3>
<p>So, when we look at many of those aspects that make up what is known as Web 2.0 or even the emerging semantic Web, we see that collaboration and user-submitted content stands at the fore. And our general power law curves then also affirm that it is a very few who supply most of that user-generated content &#8212; namely, those at the <em><strong>head end</strong></em>, the <em><strong>teeny heads</strong></em>. If those relative few individuals are not motivated, the engine that drives the social content stalls and stutters. Successful social collaboration sites are the ones that are able to marshal &#8220;large numbers of the small percentage.&#8221;</p>
<p>The natural question thus arises: What makes those &#8220;teeny heads&#8221; want to contribute? And what makes it so they want to contribute <em><strong>big</strong></em> &#8212; that is, frequently and with dedication? So, suddenly now, here&#8217;s a new success factor: to be successful as a collaboration site, you must appeal to the top 1% of users. They will drive your content generation. They are the &#8216;teeny heads&#8217; at the top of your power curve.</p>
<p>Well, things just got really more difficult. We need tools, mindshare and other intangibles to attract the &#8220;1%&#8221; that will actually generate our site&#8217;s content. But we also need easy frameworks and interfaces for the general Internet population to live comfortably within the long tail.</p>
<p>So, heads or tails?  Naahh, that&#8217;s the wrong question. Keep flipping until you get both!</p>

I remain convinced that only a few &#8220;movers&#8221; are required to start shaking the user-generated content tree. I made two changes from the original post: 1) I had to find a grainy replacement for the initial great graphic of the &#8220;teeny head&#8221;; and 2) I added the red portion to the graphic.

After all, we did our due dilgence on this company, it is not profitable — perhaps even bleeding excessively — so what went wrong?</p>
<p>Actually, to be fair, perhaps the founding entrepreneurs are having the same thoughts. We wrote the business plan, we beat the odds to even get angel and (”Isn’t <span style="font-style: italic;">that</span> special,” says the <a href="http://en.wikipedia.org/wiki/Church_Lady">Church Lady</a>) VC financing, thus we have had affirmation about our markets, technology, team and other aspects from the “smart” money, so why is it not working? Why aren’t we profitable? What went wrong?</p>
<p>Getting external financing from professional VCs is non-trivial and itself is putting a company in the “less-than-0.1% club.” And, of course, getting any financing is hard to do, be it an angel, your own checking account, your spouse or your friends and family. Forsaking Janie’s college education for a chance on a start-up requires tremendous belief and suspension of dis-belief for <strong><em><span style="text-decoration: underline;">any</span></em></strong> early investor.</p>
<p>But, the initial financing hurdle has been met. Some time has passed. Neither profits nor the plan are fulfilling themselves. What do we — obviously the smart ones since we put up the money or had the ideas — do about our belief while return is not being fulfilled?</p>
<h3>Time for Superman?</h3>
<p>In nearly two decades of mentoring various ventures I’ve observed one possible reaction is to look for Superman. If only the company had the right missing individual in a CEO or senior manager position, then many of the current problems would go away. But as my Mom used to say, nothing is easy. Easy answers can lead to uneasy situations. And, I think, the myth of Superman more often than not fits into such a facile error.</p>
<p>When things go wrong (or, at least, are not going as desired), things are tough for all of those with a stake in success. Is the source of discomfort that money was put up and is now at risk of loss? Is it that individuals were supported but are not yet achieving success? Is it ego that due diligence was made but success is looking tenuous? And, if things are going wrong or progress is disappointing, what is the root cause? Is the market needful or ready? Is the technology or product responsive or ready? Is the business model correct? Are other pieces such as partners, advisors, infrastructure, collateral, or whatever in place?</p>
<p>New people do not need to be hired to pose these questions nor to spend purposeful and thoughtful time addressing them. And, even if new people and skills are deemed critical to supplement the skills presently available, setting expectations that are too high or too superhuman are likely to not be fulfilled, take to long to do so if even achievable, and cost too much in focus and precious resources.</p>
<h3>The Kryptonite</h3>
<p>In fact, pursuing the myth of Superman can actually worsen a current situation for the following reasons:</p>
<ul>
<li><em>Supermen Are Rare</em> — there are thousands of new startups formed each year, hundreds of which receive significant venture funding from VCs, angels, or small business R&amp;D efforts or grants. Only a very small percentage achieve high returns and only a small percentage of those can be ascribed to the “superstar” performance of a specific individual. Sure, names are known and the business and trade press love to lionize these individuals. But the statistical occurrence of a clearly superior manager or executive is measured in the tenths of a single percent or less</li>
<li><em>Supermen Are Not Infallible</em> — even that small minority of individuals that do receive recognition as “superstars” may have achieved that lofty status as much due to luck or circumstance. Serially successful entrepreneurs are rarer still than one-off “superstars.” And, for those few individuals that have shown repeated success, they are more often interested in pursuing their own loves and interests and are not for hire for someone else’s venture</li>
<li><em>Supermen Are Not Obvious</em> — perhaps because of serendipity and some of the reasons above, “superstars” also defy characterization by sex, background, age, appearance, personality, education or other discernible metric. So, if a Superman is not reliably a Superman in his next engagement, nor if there is a way to reliably identify Supermen-in-waiting, then why is so much time spent on finding the unfindable?</li>
<li><em>Supermen Are Expensive</em> — both in terms of equity and compensation, any individual brought in as a savior will cost the startup plenty. Resources are always most precious and constrained for startups. Perhaps, if the identification of the “superstar” could be reliably assured, then this expense could be justified. But since that reliability is not there, the hiring may only drain limited cash and resources and create resistance by the key founders who don’t receive the Superman rents</li>
<li><em>They Can Screw Up Dynamics</em> — by the time the Superman option is considered the company has alreadly likely achieved some success, visibility and funding. Founders and key employees, not to mention early financial backers, have worked hard to bring things to their current point. Raising the Superman spectre not only affects the morale of existing players and sends a negative message but, if an individual is then subsequently hired, existing dynamics can be challenged and irreparable harmed. Of course, outside money that controls such decisions may have reached the conclusion that dynamics were already broken and needed fixing, but the likelihood of a new player augmenting and bolstering existing positive interactions is less than the opposite prospect</li>
<li><em>Finding Superman Diverts Attention</em> — a Superman initiative poses a huge opportunity cost to the limited bandwidth of existing executive and director attention within a startup. Defining the qualifications, collecting the names, conducting the recruiting, interviewing the prospects, and then deciding to offer and negotiating the compensation package are extremely time consuming activities. All time spent on this stuff is time not spent on building the company, its products and pursuing sales</li>
<li><em>In Fact, Superman May Not Exist</em> — this is actually the most interesting observation. It is seductive and a statistical error to look at the instance of a managerial or entreprenenural success and conclude it is repeatable. After all, haven’t some individuals beat the track, the stock market, or the start-up venture odds? Let me first say there are perhaps the spectacular individuals — say a Warren Buffet — who consistently outperforms the normal. But Howard Hughes did the same and still ended up with a Spruce Goose that barely flew and fingernails inches long, and there are compelling few numbers of billionaires for the millions of existing businesses. At the statistically low numbers here, we can safely say that for practical purposes Superman does not exist.</li>
</ul>
<h3>Change the Perspective, Change the Mindset</h3>
<p>Raising the Superman option only occurs when a company is in trouble and needs help. The key individuals associated with a startup — Board and management alike — are better advised to concentrate on business model, strategy, execution and maintaining focus than searching for the impossible or (at least) statistically highly unlikely.</p>
<p>When problems arise, look to problem identification and problem-solving approaches before copping out with easy Superman answers.</p>
<p>Efforts should be focused; business models should be clear; execution should be emphasized; resources should be zealously protected and stewarded; questions should be constantly asked; and team efforts and building should be fostered. Patience is not a four-letter word, especially if progress is steady and being accomplished in a cost-effective manner.</p>
<p>Nurture and training of initial founders and staff is important. Financing would not have been initially achieved without some belief in these individuals. Not now actually performing to plan is, in fact, an expected outcome, not one warranting excoriation.</p>
<p>These positive mindsets are hard to keep when the venture’s performance or sales is not meeting plan. And, of course, some of these instances will warrant abandonment of the venture rather throwing more good after bad. There are no guarantees. And mistakes get made.</p>
<p>But make the choice. Commit to the venture and improving its prospects through hard work and engagement, or walk away. Superman is a false middle ground.</p>
<h3>Don’t Get Me Wrong</h3>
<p>Please, don’t get me wrong. Without a doubt some people are better managers, some are some are better salespeople, some are better intellects, some are better strategists, some are better marketers and some are better networkers than others. Anyone who is superior, committed and a believer in the cause of your venture will likely bring some value. And there are indeed rare individuals and rare circumstances when hiring the right new executive could and should make all of the difference toward success.</p>
<p>The more important point, however, is that startups are more often than not constrained in their team and resources. Be smart about where to spend limited time and focus. Hiring good and even great people is a good focus. Searching for Superman is not. Rather than the impossible combination in a single person, look to a collective team that embodies the needed and valuable traits deemed important for your venture’s success.</p>

<h2>Serving Up Occasional Re-treads and Leftovers</h2>
<p>My wife and I are not gamblers, and were somewhat surprised to find         ourselves at our local destination casino last weekend to see a concert         by <a href="http://en.wikipedia.org/wiki/Boz_Scaggs">Boz Scaggs</a> and         to spend the night in a high-roller suite with a glassed-in shower and         electrically controlled window shades. The only missing piece was a         mirror on the ceiling. Of course there was an occasion involved, and         from top to bottom we had an absolute, total great time.</p>
<p>The highlight of the whole affair was Boz Scaggs himself and his band.         Boz Scaggs goes back to our courtship; and we celebrated our 30th         wedding anniversary this year! But, this was not a geriatric trip down         memory lane: this was top-drawer, great music and entertainment. Not to         get too excessive, but this show was close to one of the best I have         ever seen!</p>
<p>I normally would not comment on such matters on this blog. After all,         I&#8217;m generally trucking down an esoteric trail with an audience that at         most fills living rooms, not concert halls (let alone stadiums). Such         is the semantic Web today.</p>
<p>But then one of those somethings happened this week: I was asked to go down memory lane and resurrect some of my older posts. I read         quite a few from years back, and liked some of what I read. It was         actually kinda fun. And, I had forgotten many of these older hobby         horses or even that I had written them.</p>
<p>Now, in the original Stone Age days of this blog, namely 4-5 years ago,         I had like 20 &#8211; 30 readers per day. Today, I&#8217;m closer to 2500 per day,         and seemingly growing pretty steadily. I also now have a backlog of         about 400 prior posts. Most have not been read, or at least not by any         notable readership.</p>
<p>So, like Boz Skaggs, I decided I would on occasion bring back one of         those older contributions that maybe did not get too much airplay in         the older days. And, since these are re-treads, I should also         re-introduce them on Friday when the news cycle is slow and no one is         really very attentive anyway. I mean, afer all, they are only         electrons!</p>
<p><img style="border: 0px solid; width: 64px; height: 73px; float: right; margin-left: 10px;" title="Friday Brown Bag Lunch" src="../wp-content/themes/ai3/images/lunchbag_64.jpg" alt="Friday Brown Bag Lunch" hspace="5" vspace="5" align="right" /> So, with this convolution, I&#8217;m         pleased to introduce this occasional Friday re-release of selected earlier         posts. I may make some minor changes to these older posts to make them         current or correct typos and such. If I do, I will so note.</p>
<p>I do not have enough historical backlog of posts to warrant a re-tread         every Friday. But, on occasion, including this Friday, I will post         again. Look for the brown bag symbol on these reprised posts. <img src='http://www.mkbergman.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
