This looks pretty good. Thanks for also updating ProvRDF. I'll go
through it with  my changes from below.



I changed some of the equivalent classes to subclasses to avoid
unwanted side-effects.

For instance we don't want to have Involvement to be equivalent with
hadSpatialExtent min 0 Location - because then it is equivalent to
owl:Thing (!)

Inform is also an ActivityInvolvement.

I put equivalence on ActivityInvolvement and EntityInvolvement to have
"activity some Activity" and "entity some Entity". Start is not
defined as either ActivityInvolvement or EntityInvolvement as it can
play double-role and might not always be both. (However it should be
either, so this is incomplete!)


Association is not equivalent to an involvement having entity to an
agent - it could just accidentally be an agent.

However I introduced AgentInvolvement that requires the subclass (not
equivalent!!) "entity only Agent" - we could lax this to require
"entity only Agent" - but none of the subclasses would allow a
non-agent entity by my view.  This contains Association, Attribution,
End, Responsibility.

I notice Derivation is no longer a subclass of Trace - but
wasDerivedFrom is subproperty of tracedTo. Any reason for not keeping
the same hierarchy for the involvement here?


I moved hadQuoterAgent and hadQuotedAgent to be subproperties of
entity - this is a special case of Quotation as we basically need
'roles' for the 'entity' - this should be looked at later.

I moved so hadOriginalSource is not a subproperty of wasAssociatedWith
(the source is not necessarily an agent)
