Supported browsers for this release are Internet Explorer 7 and Firefox 2 & 3.This release is accompanied by several new and impressive demos in my humble opinion. These make use of the new functionalities that have been incorporated so far. Below are some important highlights.

Planning a Semantic Web site

junio 30, 2009

Rob Crowther (robert@crowther.info), Web developer, Freelance

Summary: 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. But these benefits don’t just magically appear. This article leads you through the aspects of both information architecture and general infrastructure you need in place to truly take advantage of this burgeoning opportunity.

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.
