Re: PROV-ISSUE-453 (influence identifiers): influence inference and uniqueness

Hi James,

Can I check the following:

Consider:
wasStartedBy(id1,a,e,_a1,_t1,_attrs1)
and
used(id2,a,e,_t2,_attrs2)

So, we can infer
wasInfluencedBy(id1,a,e,_attrs1)
and
wasInfluencedBy(id2,a,e,_attrs2)


And this is valid, because we allow multiple distinct influence 
relations between a pair (a,e).
Is this right?

Luc
