ISSUE-454: can the same identifier be used for different relations objects

key across relations/objectss

can the same identifier be used for different relations objects

State:

CLOSED

Product:

prov-dm-constraints

Raised by:

Luc Moreau

Opened on:

Description:

We have the following two uniqueness constraints.

http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-constraints.html#key-object
http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-constraints.html#key-relation

It is not clear to me if

entity(e123)
agent(e123)

are acceptable. (To me, they should be, since we don't state the set of agents to be disjoint from any other set)

Likewise, can we write

used(event1234,a1,e1,attrs1)
and
wasGeneratedBy(event1234,e2,a2,attrs2)

Probably not.
Note: if we allow the two above, then I am not sure that strict ordering is wise in ordering constraints.
