1. 1 SIPPING Working Group IETF 74 Dale Worley Martin Dolly Dan Petrie Profile Datasets draft-ietf-sipping-profile-datasets-03

2. 2 Changes since version -02 Reduced number of editors/authors – past editors are now in a contributors section: Sumanth Channabasappa, Sam Ganesan, Volker Hilt Defined the following terms: Profile = dataset = set of properties (name/value pairs)‏ Profile schema Profile meta-schema = schema for profile schemas Profile type (local network, device, user)‏

3. 3 Discussion Point (DP) 1  Merging rules included in schema Currently named and defined in the I-D. Proposal: Keep the merging rule specifications for each property in the profile schema Note that (instance) datasets do not specify merging rules

4. 4 Discussion Point (DP) 2  “Multi-Line” devices – e.g., with 2 logical UAs – currently handled by: Device profile – common for all users User profile - separate for each "line", the list of users is specified by the device profile Proposal: Keep this model – should suffice, noting that this is different from “Shared Line Appearance”, which is less complex

5. 5 Discussion Point (DP) 3  Relax NG schema Proposal: Keep it - everybody prefers it to XML Schema Language

6. 6 Discussion Point (DP) 4  Versioning Some elements in the schema are not defined for extensibility (e.g., enumerations)‏ Proposal: Extension done by adding properties (data items) or entire dataset types, rather than extending the range of previously-defined properties.

7. 7 Discussion Point (DP) 5  Visibility Some elements in a dataset should not be visible to the end (human) user This is separate from the concept of “locked” data, which is out of scope for this document. Proposal: Need this functionality, despite that it adds complexity Need to specify merging for visibility attribute

8. 8 Way Forward Update document based on resolution/agreement of discussion points Bi-weekly design team meetings to resolve open issues over next two months WGLC targeted to start May 30, 2009
