Subject: Re: PROV-ISSUE-383 (how-to-handle-subtypes): How to handle subtypes in PROV-DM [prov-dm]

I realized after I sent this that I was thinking in RDF mode... in PROV-N subtyping is declared using attributes, so this last comment of mine is somewhat moot.

It also turns out that I misread your original email, and on re-reading my comments don't make any sense in this context.  Best ignore them.

Sorry for the distraction.

Hi Graham,
I don't understand this, can you explain the implication of your suggestions for
both prov-dm an prov-n?

y tentative intuition, then, is this:

(1) use direct subtyping for subsets of Entity, Activity and Agent.

(2) use type annotations for suptypes of the various relations.
