Hi Sergio,
If I understand well this is a kind of specification API? The actual
implementations will be done in Jena/Marmotta/OpenRDF?

While, as I understand it, OpenRDF [*] is adopting the interface natively,
It does not look any anyone is coming forward to follow that route in
Jena. It would be be a massive decision to uproot the existing 10+
year-old APIs. A cultural aspect of Jena is preserving user code
investment.
So Jena would provide a separate API for this for the interworking case.
So far commons-rdf is mostly design - we haven't (as far as I know)
tried actually using it in a mixed environment.
Jena has a higher level interface to RDF based on graph nodes, not the
edge+global terms style of commons-rdf.
As a system, Jena has an internal storage interface that can support
multiple user APIs. A quick sketch suggests that using that will give a
commons-rdf API to Jena graphs. There's a lot more outside commons-rdf
(e.g. SPARQL query language) that is out of scope currently.
svn/git:
Jena is in svn current and likely to move to git "some time". We get
pull requests from the github Apache mirror quite regularly and it all
just works (except for occasional diff format issues).
