Chair exhorts everyone to get cracking on the policy use cases.
New issues:
None.
Agenda items:
Which version of WS-Addressing?
Version skew if WSDM references WSA both directly and indirectly
(through WSN). WSN refers to 2003 version, not member submission
version. Steve suggests amending issue 2.15 to include WSRF issue 43
as well as WSRF 30 in the resolution. Net effect is to change URI,
normative reference. Will make resolution of 2.15 easier, bring us up
to date with WSRF and WSDM. No reason to stay at 2003.
No objections.
Anish: What if there is a new submission from WSA working group?
Steve: We warn that WSA is subject to change, we will take new
submission into account.
Remaining item from 13-0.1a review (topic faults)
Need to fix copy-paste error, split fault into "unsupported" and
"ambiguous" (getCurrentMessage only) (dmh has pen :-)
Steve's proposed resolution of 2.1 (common filter mechanism)
Puts topic, selector, precondition in <filter> element, allows
for {any}. Any number of any element allowed. Semantics of repeated
elements, order: Order and timing determined by NP. "And" implied?
Some concern about underspecification of order of evaluation. Need to
run up some use cases, clarify issues.
Peter: There shouldn't be any reason for side-effecting in filters.
(someone): Not a filter doesn't commute with selector.
PN: which is why it's not a filter.
AI: dmh: take cut at issues (commutativity, side-effects). Would like
to find overarching statement of semantics (e.g., order MUST not
matter) in order to short-circuit detailed issues.
Peter: Empty filter vs. no filter element at all? Sgg: Filter should
be optional, if present must have content. Fix XSD? (sgg)
Sgg: Collapse topic, selector, precondition ResourceProperty to filter
property (TODO).
Sanjay: Not consistent with F2F minutes? Sgg: Consistent with minutes
of proposed resolution (not Steve's earlier proposal in minutes).
SubscriptionManager interface (2.23)
(should be in section 5, headings in doc are hosed)
Basic ops are renew, unsubscribe. Pause/resume etc. are extensions.
Peter: BaseN does not support WSRP, so can't query termination time.
dmh: Should termination time be in core (since scheduled termination is
optional)?
pn, sgg: Consensus is that termination time is core.
dmh: hmm . . .
tom mcguire: 1.2.1 says WSRL methods needed if you implement RL.
(RECCOMENDED)
pn: 3 kinds of SM: Base, extended with WSRP, extended w/WSRP and WSRL
dmh: renew is always there
sgg: yes (but may fault)
tom: set termination time == renew, unsubscribe == destroy?
sgg: yes, need to clarify
pn: No way to find out expiration time except extended w/WSRL.
sgg, dmh: Include get expiration time in base (since renew, termination
time) are in base.
tom(?): Resulting base doesn't look any lighter than extended
sanjay: Base is independent of WSRF. Base should not use WSRF
terminology.
dmh: GC considerations: Base should not take a position, so should not
mention scheduled termination.
sanjay: Scheduled term is in base because it makes base self-contained.
pn: Sheduled term is also effectively optional in base.
dmh: Just so.
Anything else?
dmh: Minutes?
Minutes approved.
