As far as WXS' entrenchment in web service-related work, I now try to avoid it when I can. In the software I work on (a repository for "digital objects"), we initially defined one of the APIs using WSDL, bound with SOAP via HTTP, with WXS for data typing. A desire for strong typing and a percieved future pervasiveness of WXS were the strong factors. I now consider WXS to be a huge amount of overhead for our needs, and as much as the tools say they support it, it's hard to find any WXS-savvy software that doesn't include the phrase "supports a subset of ...". The result is that for myriad of insane types you can *define* in WXS, you really have to keep it as basic as possible to ensure that people can use them with their tools, much less make sense of them. Without saying anything specific about RELAX NG, I can say that people doing WS-Stuff are interested in a simpler, more practical alternative to WXS for typing. - Chris -----Original Message----- From: Simon St.Laurent [mailto:simonstl@s...] Sent: Monday, December 01, 2003 10:48 AM To: xml-dev@l...

Does anyone strongly agree or disagree with this? I'm not sure I buy it, except maybe to the extent that data heads stay far enough away from the markup that they choose tech based on what tools are most immediately available, and WXS had a head start there. For people who need to create generic environments but still insist on determinism, WXS probably has an edge. Otherwise, I don't think the generalization holds. I'm working with a group of librarians on metadata representation, all of which feels like relational database information expressed as XML, and RELAX NG was extremely helpful to getting the project started. (I'm speaking on RELAX NG to Cornell librarians on January 16 - if anyone's going to be in the Ithaca area, let me know.) I'm also fascinated by the apparent fact that RELAX NG is far more capable of describing RDF's syntactic possibilities than is W3C XML Schema. I tend to regard RDF as an uber-data project, even though its users frequently have at least familiarity with documents. I suspect there's room for a lot more experiments with RDF and XML, and hope such experiments might in the end obviate most of the need for RDF/XML per se. Even where WXS is used, I marvel at how it just doesn't quite fit. The interactions between Microsoft Excel 2003's native types and W3C XML Schema importation are complex and fascinating. Microsoft Access 2003 provides extra type information on the declarations of schemas it exports rather than rely on WXS types. I don't think any dust has settled in the schema space yet. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
