They are both Accounts. Your AccountEntities are specializationsOf (or alternatesOf) Accounts (depending on what you are modeling) and do not need to be named differently to be so. Also, a principal aspect of this issue is to rename Account to Provenance.

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).
