Ken Holman and Eric van der Vlist have set up a web site to support the ISO SC34/WG1 work on the Document Schema Definition Language (DSDL). DSDL [ISO/IEC 19757] is a relatively new project under International Organization for Standardization/International Electrotechnical Committee, Joint Technical Committee 1, Subcommittee 34, Working Group 1. The project objective is "to create a framework within which multiple validation tasks of different types can be applied to an XML document in order to achieve more complete validation results than just the application of a single technology." DSDL is to be a "multipart International Standard defining a modular set of specifications for describing the document structures, data types, and data relationships in structured information resources. Two kinds of integrated specifications are included: specifications for describing aspects of validity of a document, and rules for combining and packaging a collection of processes applicable to the task of validating a document. This integration makes DSDL applicable to both business and publishing applications of structured information resources." Much of the DSDL work is expected to be conducted via email. In addition to the moderated members-only mailing list, an open unmoderated list dsdl-comment@dsdl.org has been set up for public contributions.
