This post (and this weblog) has a new home. WS-Reliability, the Latest Installment in WS-Everything OASIS just announced a TC for WS-Reliability. The specification is a reasonable 45 pages and has some real-world features like sequence numbering built into the specification. The thing to do is see if it's reasonable by roughing out an implementation, but at first glance, it looks like good old reliable messaging with SOAP-based semantics. It would probably be better to straighten out protocol (as opposed to data) issues first, since reliable messaging over unreliable protocols doesn't make a lot of sense.  It's still nice to have a simple and general specification to work with, and the ubiquity of HTTP is unassailable. 10:36:17 PM

This post (and this weblog) has a new home. Web Services (Short) Stack My response to a question from Simon St. Laurent on the xml-dev list provoked a couple of quotations by Kendall Clarke in an article on XML.com: I would qualify the presence of UDDI [in the web services stack] -- "free love" on the business internet is a long way off. Security doesn't begin to cover trust, and that's far more important for business transactions. The answer to the question "Is there a royalty-free specification of web services choreography that legitimately combines and acknowledges the established body of knowledge on long-running transaction models, business process semantics, and cross-domain implementation realities?" is "No." 12:44:15 PM

This post (and this weblog) has a new home. Never write another XMLFilter implementation... I just put the finishing touches on a short introduction (co-authored with Oliver Becker and Petr Cimprich) to the STX streaming XML processing language.  The STX language is similar to XSLT in syntax and satisfies many of the use cases for hand-coded SAX filters. The article will be published on-line, and I'll post a link once it's up. 12:12:21 AM
