Definition
- “The Semantic Web is a project that intends to create a universal medium for information exchange by putting documents with computer-processable meaning (semantics) on the World Wide Web.” Wikipedia: Semantic Web
Technology
- XML
- RDF
- OWL an W3C standard built on top of RDF
- Semantic web applications built on top of RDF, e.g. FOAF
Alternatively, there initiative outside the W3C, like:
The relation to Web 2.0
Web 2.0 does incorporate some "semantics" but globally speaking it is much inspired by making it as simple as possible. E.g.
- Simple RSS (0.91, 2.0) instead of RSS 1.0 that was based on RDF
- Folksonomies instead of formal taxnomies metadata based on RDF semantics
- People-driven aggregation of knowledge (e.g. via syndication of the blogsphere) instead of smarter search engines. An exception are some of the best citation indexes that use both approaches.
Some examples
- FOAF ("Friends of a friend") is an RDF-based social software for social networks.
- Semantic Media Wiki] (At some DSchneider will make a test with this within this wiki)
