So my question for the wider community is to ask why
foaf:membershipClass remains largely un-used...
My suspicion is that those folk who are most into doing rich
class-centric reasoning, prefer a DL-based toolset and find FOAF and
real world FOAF data too scruffy for that environment. But I'd hope it
should be possible to take data from the messy quad-centric linked
data scene and project out clean DL-friendly chunks for class
Natural ways of grouping/classing people include by skills, employers,
roles, linkage to some focal individual (eg. "*my* co-authors), and by
geography. On Facebook or Twitter/StatusNet for example I might often
have something like an event cross my desk that I'd prefer to pass on
to a "tech people in Bristol" or "tech people in Amsterdam". There is
no way I'll maintain by hand such a people list in those sites, but
since everyone has APIs these days it is quite feasible that an
RDF/OWL based app could sort-and-categorise my contacts locally, then
push those lists up to the social network sites where they can be
Maybe these are even now still early days...?
