Subject: Minutes December 11, 2003 meeting
Attendees: Von Welch Michael McIntosh Bill Parducci Hal Lockhart Anne Anderson Seth Proctor Michiharu Kudo Tim Moses Anthony Nadalin Polar Humenn Steve Anderson Rebekah Lepro Frank Siebenlist Minutes from December 4, 2003 call were accepted without issue. Tim reviewed the submission of the v2 Draft specification. Current goal set the end of December as the dealing for completion of changes to the Draft. Tim anticipates putting out one more Draft out before the end of the year. The v2 Work Items that are currently being worked for inclusion are: #7 (Condition References), #23 (XQuery definitions for time variables), #27 (version numbers for policies). Michiharu summarized the current Condition Reference proposal thus: Polar posted to the list a mechanism for variable referencing in response to Michiharu's original proposal. Proposal A in the current proposal uses Michiharu's ApplyReference mechanism (course grained reuse); Proposal B, which incorporates Polar's suggestion, is a more flexible and fine grained mechanism for reference. Polar made the case for variable references (Proposal B) by discussing the potential for reuse for in other mechanisms due to its generic nature. Infinite recursion is possible with such a model, but most declarative systems allow for a similar approach; it typically requires some sort of recursion checking to eliminate this event. Seth brought up the issue that recursion checking may be burdensome on the PDP based on the increased logic expense typically associated with of recursion checking. The group decided that we will review the two approaches for Condition Reference and take up a vote on the ultimate solution at the next meeting (January 8, 2004). Seth asked if Work Items #45 and #49 are the same thing? The example in the current specification dealing with these issues is somewhat ambiguous. The group is asked to review the modifications Tim has made to the existing example. In particular, Seth and Michiharu have been asked to scrutinized. Seth also raised a question as to the status of Work Item #41 since it was to have a proposal by early November. Hal will resolve intentions with Daniel (owner of WI). Tim raised a question re: Work Item #37: multi-valued attributes. Rebecca had asked that attribute values for MaxOccurs be unbounded earlier. Tim made some modifications to the schema per this request and asked that she review. Michiharu raised an question with Work Item #9: hierarchical resources. There are two proposals for consideration (Anne and Simon) which requires clarification. Bill will follow up with Simon. Meeting Adjourned.
