W3C Releases Working Drafts of XML Schema Specification
Page 1 of 1
The World Wide Web Consortium (W3C) this week released the first public working drafts of the XML Schema specification, suitably called XML Schema Part 1: Structures, and XML Schema Part 2: Datatypes.
The W3C published these working drafts to ensure that the public can follow the XML Schema design work, so that the final result will be widely accepted and adopted.
XML Schema Part 1: Structures proposes the mechanisms for associating datatypes with XML element types and attributes, enabling XML software to do a manage dates, numbers, and other special forms of information. XML Schema Part 2: Datatypes proposes the methodology of describing the structure and constraining the contents of XML documents.
The Resource Description Framework (RDF) was created to integrate different types of Web-based metadata activities, such as content ratings, search engine data collection, and digital library collections. Schemas, on the other hand, will enable software to distinguish the data governed by industry-standard and vendor-specific schemas, and help applications know when it is OK to ignore information it doesn't understand, and when it should not do so.
