First Bugzilla triplify prototype released to validate ontologies for RDF (Linked Data for bugs)

In the course of trying to propose Semantic Web ontologies that would suite the needs of the free software maintainers, in the frame of Helios, here’s another step.

We’ve just released a first prototype of the use of triplify to export bug facts for bugzilla as RDF, using EvoOnt BOM, FOAF and SIOC.

You’ll find all the details here : https://picoforge.int-evry.fr/cgi-bin/twiki/view/Helios_wp3/Web/TriplifyBugzillaToRdf as well as a link to the demonstrator.

We’re now looking for candidate Bugzilla owners to test it on real bugs, and why not, to deploy it to contribute to LinkedData with bugs of OpenSource projects.

RDF from Debian bugs demonstrator online

I’ve blogged often about our efforts around RDF and UDD in recent times.

This time, we have used triplify to export contents of some tables of the Debian UDD database to provide information about Debian bugs facts as RDF feeds (using our ontology based on EvoOnt BOM).

More details at : https://picoforge.int-evry.fr/cgi-bin/twiki/view/Helios_wp3/Web/TriplifyUddToRdf including a link to the demonstration server.

2 presentations about Helios, Semantic Web, bugs, etc. at RMLL 2009

In the “Development” track of the recent LSM/RMLL 2009, we (Stephane Laurière and me) have presented two related speeches, about the use of Semantic Web technology in the frame of Open Source projects development.

Stéphane presented SWIM : Semantic Web enabled Issue Manager, which presents an integration of Semantic Web techniques in the Mandriva community support site, and on the desktop. It’s based on results of projects Nepomuk, Helios and Scribo.

I have also presented Tracking bugs on the (Semantic) Web, which explores the use of Semantic Web techniques (RDF) as a mean to render bugtrackers interoperable, to be able to track bugs to the scale of the whole Semantic Web. This is also based on the work we do in the frame of the Helios project.

Enjoy the slides attached to the linked pages above.

Quick visualization of the social network of the Gnome projects’ maintainers

Thanks to Frédéric Peters, I’ve discovered that Gnome is using DOAP to describe projects in its Git.

At http://git.gnome.org/repositories.doap, one will find the complete agregated DOAP and FOAF description for the projects of Gnome and their maintainers.

My collegue Vu, who’s researching on such social networks has graphed the following image :
which shows projects in red, and their maintainers in green.

More analysis later maybe, but the image is already nice in its own 🙂

Update : a more detailed representation is available (see comments bellow).

Excellent presentations on Development at RMLL/LSM 2009

Of course I’m a bit biased because I couldn’t attend other tracks as I was chairing the “Development” track at LSM/RMLL, and because I “selected” the speakers.

I’m really glad to have welcome so many interesting presentations on development questions in libre software projects (or with libre software).

There are much too many interesting bits to mention, and I’m still recovering from the holidays after the conference, but you’ll already find most of the slides attached to the articles (french versions) linked from : http://2009.rmll.info/-Developpement-.html

Some videos will follow sooner or later.

Enjoy !
