Hi Tim,

How do you name "Account" appearing in [2], which is a notion that 
differs from AccountEntity in [1]?

Asserters may choose the level of abstraction they wish, which can be reconciled with those that demand different levels of abstraction. For example, are you querying a particular File on a particular machine to get the provenance, or are you looking at the abstract RDF graph that exists in MANY files (and one of which may have changed). Both are handled and can be used, and coherently associated using specialization.
