PROV-ISSUE-41 (distinct-roles): Distinct roles should be SHOULD and not MUST [Conceptual Model] http://www.w3.org/2011/prov/track/issues/41 Raised by: Paul Groth On product: Conceptual Model Currently, use has the following definition with respect to roles: "A reference to a given BOB may appear in multiple use assertions that refer to a given process execution, but each of those use assertions must have a distinct role." A process execution could conceivably read the same file twice. Thus, the file would play the same role twice with respect to a process execution. It's not clear why this constraint is an absolute or the impact of making it a non-hard requirement. Although, I can see why it would be recommended practice in order to ensure disambiguation of roles. Suggested resolution, change the sentence to as follows: "A reference to a given BOB may appear in multiple use assertions that refer to a given process execution, but each of those use assertions should have a distinct role."
