[tdwg-content] Comments on Cam's RDF practical details of recording a determination What is an Occurrence? [SEC=UNCLASSIFIED]

[Bob Morris]

If machine reasoning is a goal, I would be wary of FOAF.  An OWL2-DL, or
other OWL2 tractable reasoning profile, version remains a moving target, to
the best of my knowledge.  The reasons that http://xmlns.com/foaf/spec/ is
not subject to tractable reasoning are relatively manageable, but I can no
longer find the Zimmerman proposal for a FOAF DL version referenced in the
thread ending at
http://lists.w3.org/Archives/Public/public-lod/2010Jul/0378.html

Can someone point me at a DL version of FOAF and indication that it is
actively under discussion somewhere?

Thanks
