Very interesting presentations this morning at OWF about the future of the Semantic Desktop

I’ve attended this morning the OWF session on the future Semantic Desktops, with excellent presentations by Stefan Decker (DERI) on the concepts of the Semantic Web and the Social Semantic Desktop, by the Zeitgeist project guys (Seif Lofty and Alexander Gabriel), and finally by Sebastian Trüg demonstrating the Nepomuk semantic desktop components in KDE.

It was a good occasion to meet these people (together with Henry Story) and talk a little bit about our efforts in the area of bugtracking and Semantic Web, and to discuss the future of the Baetle ontology, and do more teasing for fetchbugs4.me.

I hope some day, we integrate the models and tools so that bugs filed on bugtrackers can be referenced and manipulated with Desktop tools through interoperable APIs and common ontologies. More work ahead of us in Helios 🙂

I’ll be speaking about bugs, Helios, fetchbugs4.me at OSDC.fr

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).

Convert OWLDoc generated HTML documentation of an ontology to single HTML file

For the needs of the Helios project, I’ve written a script which uses htmldoc to convert the multi-framed HTML documentation as generated by Protege’s OWLDoc plugin to a single HTML document.

Example : the Helios_BT ontology documentation generated by OWLDoc, and the result in one single HTML document.

The Python script is at : owldoc2htmldoc.py (see also the README).

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.
