Conduct and publish the results of a critical evaluation of the basic group and membership management APIs.

Draft API specifications for the most commonly used group management functions using Swagger 2.0

Our initial assumption was that the three most basic group management calls were:
- Is this person a member of this group?
- List the members of a group
- List all the groups for which a given person is a member

U Dub’s eight most heavily used Group ops	Chris Hyzer’s top three group operations
1) isMember (or hasMember)	1) isMember (or hasMember)
2) getMembers (of a group)	2) getMembers (of a group)
7) get/search Groups (of a member)	3) getGroups (of a member)
3) getGroup
4) putGroup
5) getAllMembers (of a group)
6) putAllMembers (of a group)
8) put/delete member to/from Group

- Maarten Kremers confirmed that VOOT2 is only about GETs.
- VOOT2 protocol expressed as valid swagger2. See VOOT2 swagger yaml used for input into editor.swagger.io (to obtain resulting swagger API documentation

SCIM: See both the Protocol Specification RFC7644 and Core Schema Specification RFC7643. Marlena Erdos comment: Quite rich group operations for read (and search) and write, quite fully documented -- and quite low level. Applies to a client contacting a server (natch, but this in contrast to Grouper)

FYI, Group Mgt used in some research communities:
- VOMS - Virtual Organization Management Service. Used by the international Grid and Open Science Grid communities. Uses X.509 attribute certificates.
