Microsoft, ArborText, DataChannel and Inso Submit XML-Data Specification to W3C
REDMOND, Wash., Jan. 27, 1998 — Microsoft Corp., ArborText Inc., DataChannel Inc. and Inso Corp. today announced that the World Wide Web Consortium (W3C) has acknowledged their submission of an Extensible Markup Language (XML) data proposal. The XML-Data specification outlines richer capabilities for developers to describe and validate data, making XML even better for integrating data from multiple, disparate sources and building three-tiered Web-enabled applications. The specification is available at http://msdn.microsoft.com/xml/ and (http://www.w3.org/TR/1998/NOTE-XML-data-0105/) .
XML-Data extends the current XML specification in process at the W3C. New features of the XML-Data specification include the following:
An XML-based syntax for schemas. Schemas define the rules of an XML document, including element names, which elements can appear in combination, and which attributes are available for each element. Schemas provide an improved method of making XML-based data self-describing to applications that do not already contain built-in descriptions of the data.
A model for extending XML elements. XML-Data provides a mechanism by which developers can further specify characteristics about particular elements. This allows developers to augment schemas with additional information such as data types, inheritance, validation and presentation rules.
“XML, since its inception, has provided extraordinary promise for information sharing across the Web,” said Adam Bosworth, general manager of the server applications division at Microsoft. “XML-Data will make it possible for XML to realize this promise and will lead to the widespread sharing of information everywhere.”
“DataChannel is pleased to work with Microsoft, Inso and ArborText on the submission of the XML-Data spec to the W3C,” said Tim Gelinas, vice president of engineering at DataChannel. “XML-Data will foster the development of new and revolutionary applications for the exchange of data between Web-based applications.”
XML-Data Makes XML Even More Extensible and Powerful
With the XML-based syntax for schemas outlined in the XML-Data specification, data is more self-describing. For example, a general purpose inventory-tracking application can extract information from a purchase order and find details about the record’s structure in the purchase order’s schema, without having been written specifically for purchase order processing.
In addition, with XML-Data, developers now have a model to define data types, providing information about the storage format. This allows developers to more precisely describe data for exchange between applications. XML-Data contains a large built-in set of data types, covering all popular database and programming language types, and it permits developers to define new types. For instance, the XML-Data schema could specify that the data contained between <price> tags is a number and the data contained between < birth date> tags is a date.
“XML brings to the Web an ability to model text and data more accurately and usefully than before,” said Paul Grosso, vice president of research at ArborText. “We’re excited about XML-Data because it offers strong data-typing abilities, which can increase XML’s ability to capture the rich schematic information that databases can work with today.”
With XML-Data, developers can also specify element-type inheritance, similar to that found in object-oriented programming languages. Using inheritance, a bookstore, for instance, could start with a standard electronic commerce purchase order schema, then tailor it to form a bookstore purchase order schema.
“XML gives unprecedented power and ease to authors of structured data,” said Steven J. DeRose, chief scientist at Inso and a member of the XML Committee. “XML-Data promises to make the task of exchanging information about new XML tags far easier to manage in a diverse, worldwide environment.”
