I'm not completely sure, and it probably depends what mesure mechanism
would be used, which environments, etc. But as far as I know, speaking
about RDF ontologies, it seems to me.
http://sioc-project.org/blog and their tales from the SIOCosphere will
probably give more details... unless it's shameless marketing ;)

Unless that Atom is no XML/RDF :-( And I believe RDF is a very doog
design decision for OSLC (let aside collections that use the non-RDF
Atom XML ;).

Well the same stands for the Semantic Web as a whole in any case.

It will nevertheless be more popular than OSLC ;)

sioc:Post mainly ... see http://rdfs.org/sioc/spec/#sec-overview and its
example.
As you may notice in the EvoOnt BOM Ontology [0] the bom:Issues were
inheriting from a sioc:Thread, i.e. an Issue / Change Request could as
well be the starting point of a conversation.
Same would probably hold for any Resource that users may
discuss/comment, etc.
Such inheritence design decision would probably be good for OSLC too.

Hmmm... it it needs to fit any tool (thinking about the various
different ways bugtrackers manage bug discussions for -CM here), then an
existing model that already seems to fit popular applications would
probably be useful... even if more difficult to implement than a simple
one, but it will have less shortcomings from the start (assuming that
SIOC is full-featured in my reasoning).

Hope this helps.
