Minutes - IETF61 - SIMPLE WG meeting - Washington, D.C.

(SIP for Instant Messaging and Presence Leveraging Extensions)

Summary:

MSRP:

Several changes were made in response to Sam Hartman's

security review. The group is comfortable with those changes.

The number of open issues is rapidly decreasing - we expect

these drafts to be last-called after thier next revision.

The chairs will obtain appropriate review of the drafts use

of SDP.

Presence Rules:

The group extensively discussed what it means to allow rules

based on anonymous or unauthenticated identities. No specific

decisions were made during this discussion.

Partial PIDF:

The group noted the similarity between the differencing

mechanisms in this draft and the mechanisms in XCAP. There

was consensus to work towards a common mechanism.

Partial publish/notify:

Draft will be clarified with guidelines on when to use the

partial mechanisms.

XCAP:

The group rejected a proposal to allow idempotency tests

other than GET(PUT(X))==X. Jonathan will make minor revision

to the core draft which will then be ready to submit for

publication.

Presence Data Model:

The group reached consensus that the model must provide a

way to pass potentially conflicting information through a

compositor without losing data.

The group concluded that the algorithms for applying

composition and selecting policy rules will be different.

There was extensive but inconclusive discussion around

differentiating services (tuples) based on URI equivalency.
