                 Key: CMIS-402
                 URL: http://tools.oasis-open.org/issues/browse/CMIS-402
             Project: OASIS Content Management Interoperability Services (CMIS) TC
          Issue Type: Bug
          Components: Domain Model
    Affects Versions: Draft 0.62
            Reporter: Ethan Gur-esh
            Assignee: Ethan Gur-esh


The current definition of ACE in the CMIS domain model (section 2.8.3, line 583) specifies that an ACE contains exactly one permission. 

This is problematic because in some products (or at least in SharePoint) a single ACE (in the native implementation) actually can have multiple permissions assigned to it. (I.e. a single ACE can say "Ethan can (read, delete)".) 

To conform to the CMIS spec as currently written, we'll have to do some clunky/inefficient things via our CMIS implementation (e.g. at "get" time we'll have to transform a single SharePoint ACE into multiple CMIS ACEs, and at "set" time we'll have to either do a normalization/transform to condense multiple CMIS ACEs into a single SharePoint ACE OR store more ACEs than necessary in our native implementation.)
