My presentations at fOSSa 2010

I’ve delivered 2 presentations at fOSSa 2010 in Grenoble, about :

  • Bug tracking at large scale, reporting on some of our efforts in project HELIOS (see details here)
  • Summer of code-like programs for involvment of students in FLOSS projects, replacing Albert Cohen who couldn’t make it (see the slides here)

The conference wasn’t a big event, but gathered very interesting talks, so it was an enjoyable event. Looking forward for the next edition. And thanks to the organizers for the good time.

First release (0.1) of a far from complete OSLC-CM V1 demo server

We’re working on implementing a demo/test server for the OSLC-CM V1 protocol, in order to help test client tools.

We’ve released (under a BSD license) a first 0.1 preliminary version that only supports GET queries, that’ll lead the way to an expected complete demo server of OSLC-CM V1 when the 1.0 version will be finished.

At the moment, it will only provide a minimal REST implementation of a PHP server using zend, and will produce JSON or XML/RDF views of fictionnal bugs contructed out of contents of a CSV file.

More details may be found at :, whereas the code is in the Download page there.

First webcast of a demonstrator of our bug ontology’s use

We have setup, as part of our work in Helios, a very early demonstrator of a database of RDF facts about bugs in several distributions (currently Debian and Mandriva), in order to try and validate the Ontology describing bugs that we develop.

Here’s a pointer to the first webcast on’s blog, with more details.

I’ll be speaking about bugs, Helios, at

I’ll be giving a speech on Saturday about our efforts in Helios to foster interoperability between bugtrackers and bugs modeling on the Semantic Web : Bugtracking sur le web sémantique. See you in La cité des Sciences in Paris Saturday at 14:00 (free entrance).

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 : 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.
