The Semantic Web brings with it the opportunities for users to get
smarter search results, and for site owners to get more targeted
traffic as users find what they really want. This article discusses
what you need to know to make your Web site part of the Semantic Web.
It starts with a discussion of the problems the Semantic Web tries to
solve and then moves to the technologies involved, such as Resource
Description Framework (RDF), Web Ontology Language (OWL), and SPARQL
Protocol and RDF Query Language (SPARQL). You'll see how the Semantic
Web is layered on top of the existing Web. It then covers some issues
that you want to know about when you plan a new Web site and also
gives specific examples of how to use technologies like RDFa and
Microformats to enable your existing Web site to become a part of the
Semantic Web. Although the promise of Tim Berners-Lee's Semantic Web
is yet to be fully realized, the years of thinking and research that
have gone into it are starting to bear fruit in terms of solutions to
practical problems that people face today. The strong collaboration
trends in Web 2.0 will only lead to more requirements for structured
and semantically encoded data being available on the Web. With some
planning, you can be in position to take advantage of the Semantic Web
tools which help meet that need.
