Hi Tim,

Can you clarify what you intent with "prov:follows and prov:precedes properties missing".

Follows and precedes are not part of the data model in the sense that they cannot be asserted by asserters. 

However derived ordering constraints must be satisfied for prov records.

It may be (or not) useful to be able to express these constraints in rdf, and therefore an ontological definition could make sense.  But it's not the prov-o ontology, it's in prov-o-constraints,  or whatever ontology extending prov-o.
