Meeting Web Services Addressing WG Teleconference

Last Call issue

<plh> Consolidated list of Alternatives A thru D to resolve WS ADDR LC comment

TomR: Major point is to make all of the assertions requirements
... The first two are probably non-starters
... I do not want to spend time on alternative a since it has problems
... Alternative b is just like a and has similiar problems.
... Alternative c can be made to work, but I think that its use-case is fairly small.
... Alternative d is my preference.
... These proposals pertain to the response message and can handle mixed alternatives since it pertains to a single exchange

Katy: I think that we have been over this ground before, I think that we established a need.

TomR: I think that you need to come up with a use case when a server needs to specify a delayed response.

Katy: The case is a server behind a firewall

TomR: How would it get the request in the first case?
... Is that use case strong enough to support this alternative?

MarcG: We have not talked about informational items expressed as parameters.

TomR: I guess parameters can be alternative e

Gil: Features should be weighed against their usefulness and necessity

David: In terms of use cases, Anish mentioned one where a service might take a long time to develop a response.

Gil: Parameters are low cost, but the default intersection algorithm will not deal with them.

TomR: Parameters will be passed to you.

Chris: Although I am in favor of E, one must be aware of the cost.
... The cost is the need to understand the interpretation of the parameters.
... on the other hand, dealing with all of the combinatorial mechanics, one might end up with a ridiculously complex think

MarcG: I do not think that we need to define the logic, it might be good enough to convey the information

Gil: I support alternative e and to break down the parameters to fine granularity

TomR: Do we need the complexity, isn't it enough to express what the server supports, after all, the client picks.

Bob: Are there any objections to alternative e?

Gil: if it just says "addressing" and there are no parameters, what does it mean?

<scribe> ACTION: TomR to craft some new language utilizing policy parameters by tomorrow [recorded in http://www.w3.org/2007/03/05-ws-addr-minutes.html#action01]

WS-Naming

plh: WS-Naming claims to profile ws-addressing, but violates ws-addressing

Next meeting to be March 19
