Conclusions - General discussion - 5 min. Agenda item 1: Chair (A.B.) briefly announced goals of the session: going through the issues in the Protocol I-D, finding out and closing the issues. Agenda item 2: Chair (A.B.) went through the agenda and the agenda bashing. Proposed agenda was accepted. Agenda item 3: Issue: DTDs vs. Schemas. Answer: Current version of the I-D available at: http://search.ietf.org/internet-drafts/draft-ietf-spirits-in-03.txt gives examples of utilizing DTDs as well as Schemas. SPIRITS does not mandate using one vs. another. These are just examples Agenda item 4: - Subscribing to multiple DP's; It is questionable whether SIP SUB/NOt supports such actions and whether SPIRITS needs such a way. Resolution: outside of today's scope - Example services: - ICW (section 3 of SPIRITS I-D) Resolution: no comments, proceed with the I-D. - ICIDD service call flow (section 5 of SPIRITS I-D) Resolution: no comments, proceed with the I-D. Other services? VKG proposed SMS to SIP IM as an example service for the I-D. Resolution: Flash theis idea on the mailing list to check the idea against SPIRITS charter and to gage WG's interest. - SPIRITS specific security considerations; - Unfinished portions of Section 4 Resolution: It is just a matter of time. These sections will be finished shortly. Agenda item 5. Conclusions: One of the outstanding issues, besides security, is SPIRITS MIB. Igor Faynberg proposed re-use of PINT MIB. WG will look into this. Consensus to start work on MIB when Protocol is ready to go to the Last Call. Maybe PINT MIB is a good starting point. Ask PINT MIB Doctor (Dan Ramascanu) for assistance. Respectfully submitted, Alec Brusilovsky
