Matters

<savas:weblog/>: "We are finally ready to request the community's feedback on our latest work, the SOAP Service Description Language, or SSDL. Jim and I collaborated with a small team of people to produce a description language for Web Services that we think is exciting since it encourages us to reason in terms of messages, rather than 'operations', 'interfaces', and 'inheritance', when writing contracts.
The SSDL core specification defines the format of a contract document and mechanisms for Protocol Frameworks to reference the declared messages. Protocol frameworks are used to correlate the messages into simple MEPs or complex protocols. We have made available four such protocol frameworks: MEP, CSP, Rules, and SC). There are also an SSDL high-level overview document and a whitepaper available."
