The development of the semantic web is the most exciting development underway of the web as a network. The next generation of the web, Web 3.0, is meant to signal the semantification of the web. Some useful links that help understand the semantic web better are:

• Semantic Web - The official WWW Consortium's overview of the semantic web
• Semantic Technologies at work - Examples of how semantic solutions work
• Linked Data - Using the web to connect data that wasn't previously linked
• Dublin Core Metadata Initiative - Development of interoperable metadata standards
