The W3C has posted the minutes for the workshop a couple of weeks ago, which have links to the presentations http://www.w3.org/2005/06/21-xsd-user-minutes.html and http://www.w3.org/2005/06/22-xsd-user-minutes.html The experience reports submitted in advance are at http://www.w3.org/2005/05/25-schema/all.zip I was not there, but my understanding from discussions with participants and a quick scan of the minutes is: - XSD has numerous flaws but after 4 years we are starting to get consistent implementations and real interoperability at the XML document level. - The big user problems are with schema - object mapping rather than XSD per se. Somebody (W3C, WS-I, domain-specific organizations?) should address these with best practices documents. - Many would like to see an XSD Lite that hits the 80/20 point, unfortunately everyone seems to use a different 20% of the spec and all features have *some* entrenched users. - A profile that would map cleanly onto Java / .NET / C++ data types might be feasible and useful - Schema versioning/evolution is a very hard problem ... - Popular ideas on the way forward include a) a community wiki to supplement the Primer as the source for understandable but authoritative tutorials on XSD; b) a best pratices Note on versioning; c) renewed focus on the test suite by W3C and test-driven development by implementers; d) a focus on errata by the WG. The IRC minutes end a bit abruptly just before UTC midnight, and the link in the agenda to Summary of Action Items is broken, so there might be a mechanical problem here? The topic discussed at the end was whether to go forward with XSD 1.1 or not; my sources tell me that there was little interest in 1.1 and much interest in getting the Schema WG to refocus on clarifications / tests / errrata. I hope people who were there or who have read the minutes chime in with their perceptions, clarifications, and corrections to this summary.
