Abstract:In the historical development of markup languages, few innovations
have been more important than the introduction of the notion of
document grammars for constraining documents and defining document
types. Both SGML (ISO 8870) and XML 1.0 define a specialized
notation (the DTD) for defining document grammars; more recently a
number of alternative languages have been proposed.
The W3C XML Schema language replicates the essential functionality
of DTDs, and adds a number of features: the use of XML instance
syntax rather than an ad hoc notation, clear relationships between
schemas and namespaces, a systematic distinction between element
types and data types, and a single-inheritance form of type
derivation.
In this talk, Michael Sperberg-McQueen, who serves as co-chair of
the W3C XML Schema Working Group, will discuss the fundamental
design issues of schema languages, and the choices made by the W3C
group in defining XML Schema.
Biography:Michael Sperberg-McQueen is the W3C Architecture Domain Leader. He
serves as co-chair (with Dave Hollander) of the XML Schema Working
Group, which is part of the W3C XML Activity, and of the XML
Coordination Group. Before the XML Schema work started, he served as
co-editor (with Tim Bray and Jean Paoli) of the first edition of the
W3C Recommendation XML 1.0. He works full-time for W3C from his home
in Española, New Mexico. From 1988 to 2001, Michael served as editor
in chief of the Text Encoding Initiative, an international
cooperative project to develop and disseminate guidelines for the
encoding and interchange of electronic texts for research
purposes. He also serves as co-coordinator of the Model Editions
Partnership, a project to apply the TEI guidelines to the creation
of electronic historical documentary editions. Michael holds a
Ph.D. in comparative literature from Stanford University.
