Subject: Credentials Collector and WS-Trust...
I had an action item to draft something for Maryann to take to the authors of WS-Trust. Here it is; comments and refinements welcome.
The Credentials Collector (CC) work within the OASIS Security Services Technical Committee (SS TC) is currently targeted toward inclusion in SAML 2.0, which is scheduled for Committee Specification by the end of 2003. There is interest within the SS TC in making use of the WS-Trust specification for some of this work (e.g., in profiling WS-Trust for SAML CC environments).
There is a preference, if possible, to incorporate portions of the WS-Trust schema "by reference"; that is, to simply refer to schema elements defined in another standard. In order to do this and still meet the SS TC time frame of the end of 2003, it would be necessary for WS-Trust to be a recognized work product of an international, formal, and open standards body by July 1, 2003. The question to the WS-Trust authors, then, is this: "Does this time frame align with your intentions and expectations for the WS-Trust specification?"
If WS-Trust is not expected to be within a standards organization by this time, then the SS TC would be willing to incorporate portions of the WS-Trust schema "by value"; that is, to copy relevant schema elements into an SS TC specification under a SAML-defined name space. For this alternative scenario, the question to the WS-Trust authors is this: "Would you be willing to officially submit the WS-Trust specification to the SS TC for this purpose, under the official OASIS rules regarding submissions to Technical Committees?"
A response from the WS-Trust authors as soon as possible would be greatly appreciated. The SS TC plans to determine our course of action on this topic on the next TC conference call (April 1, 2003).
