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
I was thoroughly delighted to learn recently that FOAF uses terms in almost
exactly the same way that I had structured my "Agents" data (right down to
the same exat terms, in most cases). I plan to move forward with the FOAF
terms that are relevant (thanks to John W. for pointing this out to me at
TDWG).
