 No, the idea is just to release the ontology files in a TRIG format in a
well-known directory ($(PREFIX)/ontologies IIRC) + some HTML doc (so you can
browse the ontology docs offline)

 No examples or test-cases for the ontology. There is no code: just the
ontology definition.

 No, the package only provide the ontologies. Each project decides what to
do with them: tracker uses the ontologies to generate the DB schema, other
projects have a generic triplet store and use the ontology in their own
way... The same applies to libraries: it is not clear how to expose SparQL
in a programatic way, so each library can decide how to generate its own
API.

 For some reason i cannot access to the links published in the mailing list
(it asks for password). I can access going to the project web page and
accessing trac from there.

 I never used ruby but i feel comfortable in python. I need to check the
redland bindings.
