The Group discussed the URN MACE space; others are using what is there, and could use guidance on when to define new attributes, how to create acceptable attributes, etc. [AI] {Keith and Nate} will work up a first draft on attribute use, and place it in the wiki.

[AI] {Keith} will work on the simplifying the MACE home page. [AI] {Keith} will contact (Walter Cohen and John} about contributing towards requirements.

The Group discussed semantics of attributes such as student/employee number, peopleID, campusID, netID, targeted, etc. Should ePPN be privacy preserving? There was a suggestion to create use cases around ePPN in a federated context for better understanding. This may be a good topic for the Monday morning Directories Bof (8:30am) at the Spring Internet2 Member Meeting <http://events.internet2.edu/2006/spring-mm/>.

The next MACE-Dir WG conference call will be on Monday, April 10, 2006 at 4:30pm ET.
