Changes in WS-Policy Proposed Recommendation Drafts

A list of changes since the Candidate Recommendation drafts is at http://asir.selvasingh.com/blog/changes-in-ws-policy-pr.html.

WS-Policy is W3C Proposed Recommendation!

On July 6th, the W3C published the Web Services Policy specifications (Framework and Attachment) as Proposed Recommendations. Web Services Policy is a metadata language that extends the foundation on which to build interoperable Web services. There is a strong community of active members in the W3C WS-Policy Working Group. Ten companies participated in the interop testing during the W3C implementation gathering phase. Windows Communication Foundation enables features such as security, reliability, transaction and message optimization using the Web Services Policy language.

Check out Updated WS-MetadataExchange Specification

WS-MetadataExchange has been republished based on community feedback. Updates include the use of the WS-Transfer Get operation for the retrieval of metadata and the description of how to push metadata to consumers using WS-Addressing Endpoint References.

At Microsoft, I am a technical diplomat and responsible for standardizing and building industry momentum around WS-* metadata specifications such as WS-MetadataExchange and WS-Policy. For this publication, I had the pleasure of working with specification authors from BEA, IBM, CA, Microsoft, SAP, Sun and webMethods.

Check out 'Understanding Web Services Policy' Paper

This morning, Microsoft published the 'Understanding Web Services Policy' white paper, which I co-authored with Dan Roth.

Understanding Web Services Policy is an introductory description of the Web Services Policy language. This document describes the policy language features using numerous examples. This document is:

• for product decision makers who need to know the features of the language and how policy automates Web service interactions,
• for policy expression authors who need to understand the syntax of the language and understand how to build consistent policy expressions,
• for policy implementers whose software modules read and write policy expressions and
• for policy assertion authors who need to know the features of the language and understand the requirements for describing policy assertions.

For this white paper, I had the pleasure of working with Paul Cotton, Colleen Evans, Kirill Gavrylyuk, Martin Gudgin, Ram Jeyaraman, Andrew Layman, Jonathan Marsh, Jeffrey Schlimmer, Daniel Roth,  Jorgen Thelin  and Kyle Young. Writing this paper was satisfying and a great learning experience.

W3C Creates WS-Policy WG

Last Thursday, W3C created a Working Group to refine the WS-Policy and WS-PolicyAttachment submission and produce W3C Recommendations for Web services Policy. Paul Cotton (Microsoft) and Chris Ferris (IBM) are the co-chairs for this WG.

I will represent Microsoft in this Working Group. I am looking forward to this Working Group and working with Paul, Chris and other participants. W3C member companies may join this Working Group by filling up the participation form.

Industry Demonstrates WS-Policy Interop

WS-Policy Interop Workshop was a resounding success!

Authors of the Web Services Policy specifications hosted a three day interop workshop from April 25th to 27th. This meeting was hosted by SAP at their Walldorf campus in Germany. The interop workshop was an open forum for Web Services Policy implementors to test round 3 security policy interop scenarios, run round 1 and 2 unit test cases and offer feedback.

There were 15 participants representing 7 compaines at the workshop: BEA Systems, IBM, Layer 7 Technologies, Microsoft, SAP, Sun and WSO2.
