*Discussion*

{Roland} discussed the status of OM – the current version is stable and ready for production; the last item to complete is documentation. A few changes have been made to the identifier for checksum. There has been some interest outside of Sweden. While {Roland} is looking at how to route packets, {Leif Johansson} has explored a Jabber-based method to publish and subscribe. They are discussing how to join these two efforts, by standardizing the message format, such that the values are similar in their basic structure. This is more focused on middleware, while OM is focused on synchronizing the sources. The Group expressed interest in learning more about how {Leif and Roland's} work compliment each other. [AI] {Keith} will invite Leif Johansson to Internet2 Member Meeting and the MACE dinner.

{Leif} has also looked at logging entries, but this seems too slow, and is now looking at fstore for usage. Similarly, {Bruce Barton} has been working on repositories. [AI] {Keith} will ask {Bruce Barton} to send his ref work to the MACE-Directory Group.

{Walter} has continued to receive inquiries regarding Nexus documentation and code, and has decided to work on putting this information on a wiki dedicated to Nexus work. [AI] {Walter} will send a URL to the list with Nexus code and documentation, as it is made available.

A few minor changes were suggested to the X.500 and LDAP attribute profile for SAML. The MACE-Dir SAML Attribute Profiles draft document can be found off the link: <http://middleware.internet2.edu/dir/#Docs>. the next step will be to formally request that the MACE Working Group promotes the document to "Last Call" status. Ideally the document will be viewed by an audience extending beyond the MACE-Dir circle.

The Group discussed XML fragments as attribute values (cf. Keith, et al. email on 2/26). In what form should attributes be stored, to best facilitate searching and provide just representation? Are there sufficient use cases to support a need for others beyond the standard? [AI] {Tom} will email the list with a discussion starter based on the Signet privilege document and LDAP.

Attribute names (and values) urn:oid:n.n.n.n. vs. urn:mace:foo:attribute-def was another topic stemming from the mailing list (cf. Keith et al email 26-Feb "Another fork in the road…."). The Group discussed pros and cons of using the OID vs. attribute-def.

The next MACE-Dir WG conference call will be on Monday, March 13, 2006 at 4:30pm ET.
