Ralph,

I agree with the distinction that you draw between supersedes and wasRevisionOf.
Unfortunately, PROV does not provide the former.

Do you view supersedes as a sub property of wasRevisionOf?

If so, I recommend that you go ahead and define this in your extension of PROV-O.

Regards,
Tim

Whereas when something is a revision of something else all versions my still be valid. We see this in many document-centric environments. For example at NASA, a specification for telemetry and commanding of vehicles existed in a number of concurrently valid revisions (REV A, REV B, etc.).  Each revision having justification in specific contexts-of-use. Moreover 'supersedes' and 'supersededBy' are very commonly used at W3C.
