Hi Bob, Paolo,

Yes, we had the exact same discussion last week :) The conclusion was that
the inference of Agent-ness can be drawn based on the range of
oa:annotatedBy / oa:serializedBy, or the domain of the various foaf
properties.  So requiring the assertion to be explicit was unnecessary.

The options seem to be:
* Status quo, but make it explicit in the description of the Provenance
Agents section
* Create our own SoftwareAgent subClass of foaf:Agent
* Convince Dan to add one to foaf
