Introduction to the Semantic Web

Ivan Herman, W3C Head of Offices
Edinburgh, 7 April, 2004

Slides of the presentation given at the Visualisation Ontology Workshop, organized by the National e-Science Centre, on the 7th of April, 2004, in Edinburgh, United Kingdom.

If your browser is enabled for SVG, I advise you to view the slideset in SVG. You may want to check the SVG Implementations page for more details on players and on the latest versions. Otherwise, you can use the links to the HTML slides below, but you will loose, for example, some scaling and animation effects. Besides, the slides look much nicer in SVG...

Note: if you want to use Adobe’s SVG plugin, you must use the latest, ASV6 version for these slides.
