Hello: Asit: Thank you very much for the pointer. I intend to attend today's teleconference, but I might fail to do so, so here are my views on PROS and CONS: PROS: Quote: from http://www.w3.org/2006/04/ws-policy-charter.html "Web Services Policy defines a flexible policy data model and an extensible grammar for expressing the capabilities, requirements and general characteristics of a Web service, and defines mechanisms for associating policies with Web service constructs. Web Services Policy is used to convey the conditions for an interaction between a Web service requester and a Web service provider." It would be good to have this related part in WS-Agreement described in a compatible way as that would make acceptance of WS-Agreement easier. CONS: 1)Adopting WS-Policy would mean that WS-Agreement would depend on a specification which still needs to be agreeed to. While the charter does say that "Therefore, this Working Group shall be schedule-driven and Web Services Policy shall remain compatible with and to the extent possible accommodate the use of these existing policy assertions. " Until the final draft is out, one may not know what will stay stable. The end date is 31 December 2007 which is a year and a half away. I think many people have been waiting for WS-Agreement spec to be completed and to have to really wait more might have negative effects. 2)Adopting WS-Policy would mean that there would be need to change the current implementations. I do not know how many implementations of WS-policy there are in the world but to have to modify the current imlplementation would have some negative issues (at least for the implementation people) for getting interoperability etc. 3)(This is a minor issue) Since this has a large impact, we might need another call of public comments. All in all I would suggest that for this version of the spec, we should stick to the current spec to be released and consider the modifications for the next version of the specification.
