Re: whine about dctypes:Software

Antoine,
FOAF has always been our first pick, we are on the same page for that.
The issue came up when talking about Software Agents, what do we do there?

We can certainly say:
:paolo a foaf:Person, prov:Agent;

But for a software agent we would have:
:tool a prov:SoftwareAgent
with no link to FOAF as PROV does not link them.
Are we happy with this?

The other option would be:
:tool a oa:SoftwareAgent (subclass of foaf:Agent).
