About room membership

Room members are a set of repository users, groups, and roles that the room creator (or a room owner) has added to the room’s member list.

Each room member has either a Contributor or Owner role in the room.

Contributor is listed on the ACL of all room objects, usually granting Read permission over them. Most room members are contributors.
Owner permits member list management and is listed on the ACL of all room objects, usually granting Delete permission over them.

Local roles are in effect only for room objects and locations; they have no meaning outside of a room.

If a member directly assigned to the Contributors role is also in the Owners role indirectly (for example, via a group), then the Owners role takes precedence for that member.

Room owners can create private, local groups of room members, which support custom roles within the room (“Spec Approvers,” for example). The name of a local group must be unique within the room.
