TermIt

As a system admin, I want the system to support different roles of users w.r.t. individual vocabularies. Thus, only authorized users should be able to make significant changes to a vocabulary.

The roles may support the following rights:

1. View vocabulary terms, their occurrences in documents, comment on terms
2. Add terms (suggested only), annotate documents with term occurrences
3. Maintain vocabulary - update terms, approve new terms, approve term occurrences, remove terms

Acceptance criteria:

• TBD
