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 <a href="http://xmlns.com/foaf/spec/" target="_blank">http://xmlns.com/foaf/spec/</a> 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 <a href="http://lists.w3.org/Archives/Public/public-lod/2010Jul/0378.html">http://lists.w3.org/Archives/Public/public-lod/2010Jul/0378.html</a><br>
<br>Can someone point me at a DL version of FOAF and indication that it is actively under discussion somewhere?<br><br>Thanks<br><br><br><div class="gmail_quote">On Tue, Nov 2, 2010 at 10:38 PM, Richard Pyle <span dir="ltr"><<a href="mailto:deepreef@bishopmuseum.org">deepreef@bishopmuseum.org</a>></span> wrote:<br>

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