ITRI SEMINAR Thursday 30th October at 12.00 "Separating presentation from structure: an introduction to XML and XSL" Henry S. Thompson Language Technology Group, HCRC University of Edinburgh XML (eXtensible Markup Language) is a draft standard of the W3C, the committee which oversees the World-Wide Web. It is intended to bridge the gap between HTML (fixed tag set, too presentation-oriented) and SGML (too complex, not presentation-oriented enough), and accordingly has been called SGML-Lite or HTML-Heavy. XSL (eXtensible Style Language) is a proposal for a W3C standard, intended to provide a mechanism for associating style information with arbitrary XML documents, so they can be rendered for screen or print delivery. I've been involved in drafting both of them, and in this talk I'll introduce both standards at a modest level of technical detail, and then suggest how I think their advent will impact on the business of computational linguistics.
