On January 5, 1998, a new (revised) submission on XML-Data was presented to the W3C by Microsoft, ArborText, DataChannel, and Inso. Reference: W3C Note 05 Jan 1998. Authors: Andrew Layman, Edward Jung, Eve Maler, Henry S. Thompson, Jean Paoli, John Tigue, Norbert H. Mikula, and Steve DeRose. According to the introduction, XML-Data "describes an XML vocabulary for schemas, that is, for defining and documenting object classes. It can be used for classes which as strictly syntactic (for example, XML) or those which indicate concepts and relations among concepts (as used in relational databases, KR graphs and RDF). The former are called 'syntactic schemas;' the latter 'conceptual schemas.' The text of this NOTE thus "provides a specification (XML-Data) for describing and exchanging structured and networked data on the Web. Such exchange is facilitated by schemas defining the characteristics of classes of objects. The objects can be syntactic constructs such as are used in XML instances, or may be more abstract such as are found in databases, information models or directed, labeled graphs. This paper describes an XML vocabulary for schemas. One immediate implication of these ideas is a substantive part of the functionalities of XML document types can now be described using the XML instance syntax itself, rather than DTD syntax. We expect XML-Data to be useful for a wide range of applications, such as describing database transfers or remotely-located Web resources."
