This document describes how VO membership and roles from multiple AAs should be combined. There are two classic use cases: interdisciplinary (user is member of more than one VO) and the other is infrastructure specific (how it processes information from several AAs relating to distinct VOs.) The latter may now be covered by I047?
This document should cover:
- Meta-attributes of user attributes - e.g. their provenance and LoA
- Possibly, implementation of this in a practical schema
