Re: PROV-ISSUE-337 (agent-and-entity): agent should not be a subclass of entity [prov-dm]

Hi,

Following up, it seems that the point would to be to ensure that
people have to say whether their agent is an entity or activity.

Is that a correct summary?

My feeling is that it's one of the three core classes and should be
able to stand on its own but in order to describe an agents provenance
you need to make it either an entity or an activity.

Thanks
Paul
