Hi Bobby,

Ok, in a nutshell, you need to start to expose the data you have on a site (which is currently marked up in HTML presumably) as RDF. This may take the form of RDF/XML descriptions published alongside regular HTML pages (as is the case with e.g. [1]), or of RDF descriptions embedded within HTML pages, using a syntax such as RDFa [2] or eRDF [3][4].

Which of these approaches suits you best will depend on the context - both have their pros and cons. I tend to favour the former, but that's just my preference.

If you publish data in RDF you should also make sure you link to other RDF data on the Web. What's a Web without links, right? [5] sets out how to go about doing this, and has lots of general information about and recipes demonstrating how to publish RDF data on the Web. Appendix B [6] might be a good place to start, as it works through a simple example with reference to other parts of the document for more details.

Probably yes, and also we can expect to see (in fact are already seeing) new search engines designed specifically for the Semantic Web, e.g. [7].

HTH,

Tom.
