• Policy Primer Finalized

  After six weeks of comments and editing the primer on WS-Policy 1.5 that I mentioned earlier has been published by the working group. The primer is an explanation of how to use policy with web services along with best practice guidelines for policy authors. These are published as two separate documents on the W3C web site: Web Services Policy 1.5 - Primer Web Services Policy 1.5 - Guidelines for Policy Assertion Authors I'd recommend reading these if you are writing policy expressions by hand, writing software that deals with policy expressions, or defining your own policy assertions for other people to use.

You can get both of these documents from the W3C web site: Web Services Policy 1.5 - Primer Web Services Policy 1.5 - Guidelines for Policy Assertion Authors Copies of the standard itself are linked from the earlier announcement I made .

• WS-Addressing Metadata and WS-Policy Completed

  Two new standards were published yesterday by W3C that cover various aspects of web service metadata. WS-Policy is one of the family of general mechanisms used to describe service requirements and capabilities. Policy attachments supplement the general mechanism to describe how policy is specifically tied to a service description language, such as WSDL. Finally, WS-Addressing Metadata explains how addressing concepts should appear in WSDL, how WSDL should appear in addresses, and how addressing is described through policy. Look for these standards to be supported in the upcoming Orcas release. You can get all of these specifications at the W3C site.
