clipped from: www.xml.com The major center of Semantic Web-related development thus far has been in the area of RDF. The creation of semantically-richer documents is a relatively easy task, so most of the effort has been concentrated on accumulating the data, storing it and querying it. RDF/XML provides a useful intermediate syntax which, when combined with tools like XSLT, allows multiple data sources to be combined.
Further details on RDF tools and applications can be obtained from the W3C's RDF home page, and the RDF category of XMLhack. In this section I will concentrate on introducing tools useful for making a relatively speedy start with Semantic Web development.
