Changes to Content Item content model proposed by Mitch

Continued from yesterday. Read this to see how...

• Leave display name in place - done
• Delete Projects attribute -- but not project Kind - done
• Delete groups and "items in group" or "playlists" attributes, but not group kind - done
• Delete fyiLinks ("references") and its inverse fyiLinkedToItems - done
• delete whoAttribute, aboutAttribute, and dateAttribute -- yes --- done
• add Subject -- a multi-valued property that selects from a hierarchical enumeration - like our status mgr
• add Context -- multi-valued property (or no value) selected from user-extensible enumeration
• rename "priority" to importance. Rename enumerations to "important", "normal", "FYI" -- done
