In order to validate the ontology that we're designing to represent bug facts, we have used D2R (a relational database exporter mapping tables and columns to object-oriented entities on the Semantic Web producing RDF), to produce RDF descriptions of bugs that can be queried in order to navigate the bugs of two distributions as one single set.

We have created a webcast of this, as it requires a firefox plugin (Tabulator) to be rendered, hoping that it can provide an interesting demo of the kind of queries that may be possible with fetchbugs4.me once all bugs from all bugtrackers are modeled using the same standard format.

The example is to gather all bugs from the Debian and Mandriva bugtrackers about JUnit.

Here's the flash webcast created using wink.

This is very early proof of concept which in no way represents what fetchbugs4.me will look like, but it definitely illustrates the kind of interlinking made possible by the use of the Semantic Web standards to represent things that lived previously inside their own bugtracker's databases (silos).

We gratefully thank Mandriva and Debian (UDD maintainers) for having helped us get this sample data from their bugs in order to develop the ontology and test it (in the frame of the Helios project).
