For an example of what kind of RDF metadata could be obtained for Debian bugs, here's a server we have setup, which provides some RDF descriptions of bugs out of what is contained in the UDD database :
http://testforge.int-evry.fr/d2r-server/
This is work in progress and not meant for end-users. For reference on how we installed D2R to deploy this : https://picoforge.int-evry.fr/cgi-bin/twiki/view/Helios_wp3/Web/UltimateDebianDatabaseToRDF
One will find metadata about bugs, but also some metadata about Debian packages (minimal), or Debbugs users (bug submitters), and Debian developers (out of carnivore), as SIOC and FOAF bits.
Given one bug number, one may get an XML/RDF version using :
curl -H 'Accept: application/rdf+xml' http://testforge.int-evry.fr/d2r-server/data/debbugs/585740
or the N3 version with :
curl -H 'Accept: text/rdf+n3' http://testforge.int-evry.fr/d2r-server/data/debbugs/585740
Btw, on our D2R server, one can also query custom searches using SPARQL. For instance :
http://testforge.int-evry.fr/d2r-server/snorql/?query=SELECT+DISTINCT+*+WHERE+{%0D%0A++%3Fs+%3Fp+%3Fo.%0D%0A++%3Fs+owl%3AsameAs+%3Chttp%3A%2F%2Fbugs.debian.org%2F585740%3E.%0D%0A}%0D%0ALIMIT+10 which will search bug properties for bug #585740 :
SELECT DISTINCT * WHERE {
?s ?p ?o.
?s owl:sameAs <http://bugs.debian.org/585740>.
}
LIMIT 10
About people, for an example, here's my FOAF profile : http://testforge.int-evry.fr/d2r-server/resource/foafcarnivore/6688a14521cd97db162af8f9757f2e2232300e50
Given one's email address, it's easy to access one's FOAF profile there with for instance :
curl -H 'Accept: application/rdf+xml' http://testforge.int-evry.fr/d2r-server/data/foafcarnivore/`echo -n "mailto:$DEBEMAIL"; | sha1sum | sed 's/ .*$//'`
Any comments welcome.
