RDF and Topic Maps

A small document published by KTWeb reports that: "As early as October 2000, Gartner Group experts predicted that “50 percent of portal and search engine providers would be using technologies on a Topic Map basis in the next three years”. More recent forecasts have been less enthusiastic, but still consider Topic Maps as having a high probability to become a “mainstream technology” by 2003; whereas METAGroup estimations see the technology significantly hitting the market by 2005-2007, with a potential over $1 billion." Topic Map Constraint Language is something that I hadn't seen before being analogous to OWL and RDF Schema. It's good to see another Australian organisation looking at RDF and Topic Maps too.
