The Semantic Web

As Tim Berners-Lee and others have described it, the Semantic Web creates a web of data that allows computers to find, extract, share, re-use information, and potentially even reason with it. Semantic content can be embedded in web pages, published from databases, and gathered into online repositories. Most important, semantic data itself contains “meta-information” so that other services are able to make sense of it. For example, the Semantic Web uses markup not only to indicate how something should be rendered, but also to express content (e.g. the authorship, title, and date of an article).

The Semantic Web is the next step in the evolution of the Internet.
