Making data a first-class Web citizen

Vuk Miličić — Wed, 13 Mar 2013 23:28:24 +0000

Working on my startup, Faviki, I have realized how hard it is to get even basic data about a webpage. Faviki is a bookmarking app that lets users connect webpages with structured data from DBpedia. I was trying hard to figure out how to take it to the next level — to get more data [...]

Solving Linked Data problems with Hypernotation (DBpedia example)

Vuk Miličić — Thu, 08 Mar 2012 17:19:51 +0000

In this post I will present a real use case showing what Hypernotation looks like in practice. I have chosen one of the most popular datasets in Linked Data – DBPedia, and published its dataset using Hypernotation principles. It’s published on hypernotation.org – the homepage contains some friendly examples, so I invite you to visit [...]

An example of Hypernotation

Vuk Miličić — Mon, 23 Jan 2012 11:33:22 +0000

Let’s publish some data using Hypernotation. I am going to use the same (Chuck Norris) RDF example I have used on the blog so far. You can see the published data on http://milicicvuk.com/data_ and the prefix mappings on http://milicicvuk.com/prefix_. The domain is different for obvious reasons – I used my domain instead of http://chucknorris.com, but [...]

Hypernotation: Classification of hyperNodes

Vuk Miličić — Sat, 14 Jan 2012 15:57:45 +0000

In the previous post I discussed how RDF and Object-oriented model can happily live together. In this post, I am going to talk about various types of nodes in the Web of data graph and different ways to classify them. In the OO model, variables can be assigned objects, arrays, primitive data types (numbers, string, [...]

Bringing together the RDF and OO models in the Semantic Web

Vuk Miličić — Thu, 22 Dec 2011 19:17:02 +0000

The RDF model has many similarities to the object-oriented model. These are described in A Semantic Web Primer for Object-Oriented Software Developers: Domain models consist of classes, properties and instances (individuals). Classes can be arranged in a subclass hierarchy with inheritance. Properties can take objects or primitive values (literals) as values. The same document states [...]

Links in Hypernotation

Vuk Miličić — Wed, 14 Dec 2011 17:15:01 +0000

In one of the previous posts I discussed the idea of two types of links on the Web: tree links and graph links. The Web can be seen as a collection of trees with hyperlinks connecting random nodes of these trees. These hyperlinks are what cause the trees to become graphs, thus the name “graph” [...]

Introducing Hypernotation, an alternative to Linked Data

Vuk Miličić — Thu, 17 Nov 2011 18:39:35 +0000

URL, URI, IRI, URIref, CURIE, QName, slash URIs, hash URIs, bnodes, information resources, non-information resources, dereferencability, HTTP 303, redirection, content-negotiation, RDF model, RDF syntax, RDFa core, RDFa lite, Microdata, Turtle, N3, RDF/XML, JSON-LD, RDF/JSON… Want to publish some data? Well, these are some of the things you will have to learn and understand to do [...]

The Challenge of Building the Semantic Web

Vuk Miličić — Thu, 20 Oct 2011 15:59:38 +0000

The Semantic Web is often described as an extension of the current Web. The idea of what extending the Web should look like can be seen in Linked Data. In order to better understand the importance of Linked Data, one has to understand the context in which it emerged, i.e. the problem it has been [...]

What the Web looks like

Vuk Miličić — Tue, 11 Oct 2011 18:04:48 +0000

How do you imagine the Web (or do you at all)? I imagine it like this: First, let’s imagine a small website. The website typically has a hierarchical structure, i.e. a tree: Here, the circles are web pages – the big one is a homepage, smaller circles are the next level of hierarchy and so [...]

Two types of links on the Web

Vuk Miličić — Mon, 10 Oct 2011 14:09:51 +0000

In the last post I discussed the hierarchical aspect of the Web, suggesting that there are two types of links on the Web: tree links and graph links. Tree links The Web consists of web sites, which typically have a tree structure, i.e. one that involves parent-child links between the various levels of the hierarchy. [...]
