Re: use case agent

Hi Jun

Why did you include the distinction between the two kinds of agent in the provenance vocabulary?

Knowing "who" is an important part of provenance. Indeed I think it's often the first thing people think about when they think provenance. 

Furthermore, our goal shouldn't be to minimal but useful. We need to be pragmatic about what is necessary for adoption and use. Essentially, I think suggestions need to take into account issue 134

Note that Agent subclasses are not in anyway limited.

Cheers

If they want, ppl can use the provenance vocabulary to express human and non-human, whose superclass should be totally interoperable with agent from prov. this should be the way forward,no? Using our standard as the bridge for interoperability rather than trying to cover everything.

I would like to note that there was already an issue raised and resolved around this typing. The issue defined several use cases and identified prior work. The issue was resolved by the introduction of the definition of agent and its types.
