Fair enough, but I guess I'd still think of associated as a generic relationship and make sure we identify the role as well as the source and target. I don't see people wanting to talk about association#3 versus the association of Jim with W3CProv in role contributor where those three things (two entities and the role) are in the universe of discourse (or perhaps role is more of a boundary concept ala my comments on attributes, etc.

+0 - these seem like 'sub-class of' to me - having an identifier for the general relationship type along with the source and target seem to be enough to identify a particular relationship instance. +0 because they are still domain concepts and hence in the universe in that sense

I don't think it's the case:
- an activity may be associated with an agent with different roles.
- e2 could be derived (precise derivation with activity a) from e1, multiple times, maybe because e1 is used by a several times.
