As part of the GML Week Part 2 we’re releasing this code today, maybe it inspires you to create something crazy based on it. Copyleft!

This is how it looks like:

Yesterday we announced the GML 1.0 spec, a canonical reference for what constitutes Graffiti Markup Language. Today I’m pleased to announce the GML Syntax Validator, a tool to help developers working on new GML applications debug & optimize their Graffiti Markup Language files. Just say “NO!” to bad GML.

A “Validate This” button is now available in the sidebar of every 000000book tag page, or you can upload GML directly via file, form, or a simple API. Check out some example usage.

This is a beta release and bugs/feedback are much appreciated — please email me & Evan or hit up your friendly neighborhood GML mailing list

What does it validate?

• overall document syntax (valid XML)
• presence of all required GML tags (bottom of the page – drawing, stroke, tag, pt, x/y)
• verifies point data falls between 0.0 and 1.0 values
• client description (info about your app)
• your <environment> description (e.g. <up> vector & <screenBounds>, since all screens are different)
• recommendations — e.g. adding a consistent <uniqueKey> value, like an iPhone UUID or hashed computer MAC address. This allows users to enable 00000book device pairing for tags uploaded from your app

The GML Field Recorder Challenge is a DIY hardware and software solution for unobtrusively recording graffiti motion data during a graffiti writer’s normal practice in the city. The winning project will be an easy to follow instruction set that can be reproduced by graffiti writers and amateur technologists. The goal is to create a device that will document a night of graffiti bombing into an easily retrievable series of Graffiti Markup Language (.gml) files while not interfering with the normal process of writing graffiti. The solution should be easy to produce, lightweight, open source, cheap, secure, and require little to no setup and calibration. The first person or team to create the device and publish corresponding source code and HOW TO guides (as outlined in the rules) will receive €1,200. For a complete list of design requirements go to graffitimarkuplanguage.com/challenges/gml-field-recorder-challenge.

The GML Field Recorder Challenge (including the prize money) is funded entirely by Constant, which is a non-profit interdisciplinary arts-lab that is based and active in Brussels since 1997.

GML Week SE02 EP03 is happy to announce the public launch of the official GML community home on the Internet: graffitimarkuplanguage.com. This site will act as an archive for GML related projects, source code, updates and community discussion. graffitimarkuplanguage.com will also be home to the official (and newly updated) GML v1.0 spec document. Hackers and graffiti writers please come over and play.

The GML v1.0 Spec Doc was created by: Golan Levin, Evan Roth, Jérôme Saint-Clair, Chris Sugrue, Jamie Wilkinson and Theo Watson.

Huge thanks to Constant for their support of the GML community website and inaugural GML Challenge.

graffitimarkuplanguage.com was built in WordPress using wpfolio (THE WordPress theme for artists).

We’re proud to present the latest version of 000000book.com (Blackbook), the open database for storing & downloading Graffiti Markup Language files.

000000book lets you upload your own GML tag data, browse others, and download any tag’s GML for playback in desktop apps like Graffiti Analysis 3.0 and web apps like Canvasplayer. Software developers can easily upload tags from their own graffiti applications using 000000book’s RESTful API, for which no signup or authentication is required. For more info check out our intro to 000000book and API docs.

This release incorporates contributions from over a dozen members of the graffiti-hacking community, and GML-compatible applications are now available for tools like markers, lasers & eyetrackers, devices like the iPhone, iPad & Android phone, and bad-ass hardware like 6-axis CNC mills, automated paintball guns, and giant robot arms. We are not joking.

Lifecycle of a digitized graffiti tag

000000book website updates

• Mobile device pairing – enter your iPhone, iPad or Android handset’s unique ID to automatically have your tags attached to your 000000book account – check out your settings page.
• GML image generators – no more ugly missing thumbnails! Apps can attach a custom image when uploading their GML tag data (e.g. FatTag Deluxe), but now 000book will create a thumbnail for those who don’t. Powered by the mighty GMLImageRenderer by Muharrem Yildirim (Python) – thank you!
• Multiple tag players – in addition to the Flash GML Player by Todd Vanderlin we’ve also integrated Canvasplayer, a simple HTML5 GML playback demo made using Processing.js. We’d like to add your apps too! Please get in touch if you are making something embeddable on a webpage.

000000book API updates

• Search tags by keywords – looking for all “katsu” tags? No problem. This powers Graffiti Analysis 3.0′s new “RSS tag feed” feature and is based on work by ps / TPOLM
• GML syntax validations – why did that tag upload fail? Now you’ll know! 000book will return errors, warnings & recommendations when uploading GML via the 000book API — interactive debugger coming soon.
• Post-upload redirect options – after uploading a tag you can choose to send the user to a custom URL, back where they came from, or to the previous page (via HTTP_REFERRER)
• Check out the API Docs for more info.

Get Involved

• Writers – download DustTag or FatTag Deluxe (iPhone) or TouchTag (Android) and start uploading!
• Hackers – get on the GML mailing list and tell us about your projects! Questions & complaints always welcome
• Our IRC chat – irc://irc.freenode.net/#fatlab
• Organic, locally grown & 100% open-source

Graffiti Analysis 3.0 – “It’s hard to believe we could fit so many great ideas into something so thin.”

Break out your digital projectors, markers, turntables, lasers and 3D glasses, because Graffiti Analysis version 3.0 is finally here. For information and downloads go to graffitianalysis.com (source code available on github). Your one stop shop for ink and pixels.

New features include:
- audio input
- architectural awareness
- laser input
- keyword based .gml RSS playback
- red / cyan 3D effect

Overview:
Graffiti Analysis is an extensive ongoing study in the motion of graffiti. Custom software designed for graffiti writers creates visualizations of the often unseen gestures involved in the creation of a tag. Motion data is recorded, analyzed and archived as a Graffiti Markup Language (.gml) file, a specifically formatted XML file designed to be a common open structure for archiving gestural graffiti motion data.

Credits:
Graffiti Analysis is a project by Evan Roth. Software development by Mzz Chris Sugrue. Support for GAv3.0 from Les Grandes Traversees. Graffiti Analysis was built in Open Framewerkz, with additional code contributions from Theo Watson (laser input integration), Kyle McDonald (audio analysis) and ps / TPOLM (.gml RSS system).

GML Week II continues…

Graffiti Markup Language Week is back for a second round of studies in XML vandalism. Stay tuned to F.A.T. all week for daily GML based releases from the network of FAT fellows, friends and family.

For those not familiar with Graffiti Markup Language (.gml), it is a universal, XML-based, open file format designed to store graffiti motion data (x coordinates, y coordinates and time). The format is designed to maximize readability and ease of implementation for even hobbyist programmers, artists and graffiti writers. GML is intended to be a simple bridge between ink and code, promoting collaborations between graffiti writers and hackers. GML Week Part I can be viewed at fffff.at/tag/gmlweek.
