Re: [scim] Globally Unique Resource Identifiers

["Phil Hunt (IDM)" <[e-mail]>]

Entire set of resources means all present on the server. At least that is how I read it and how the discussion that I recall having occurred. 

There was concern about naming conflicts (causing desire for renames of immutable ids) and referential integrity as factors affecting this decision.

Even the global search functionality doesn't require global uniqueness because the combination of resourceType and id may be used to uniquely identify resources. Further, the SCIM 1.1 specification did not have this requirement, so this could make uplifting to SCIM 2.0 more difficult for some providers.
