Semantic Web

"If HTML and the Web made all the online documents look like one huge book, RDF, schema, and inference languages will make all the data in the world look like one huge database"
Tim Berners-Lee, Weaving the Web, 1999

Our guest speaker last speak gave us further insight on Semantic Web. The most interesting part of the presentation to me was popular choices for schemas that include:

-FOAF
-Creative Commons: (Embeds RDF in mbps)
-Music Brainz
-DC: Dublin Care
-RDF

Schemas are sometimes called vocabularies, and there are many many schemas!
We also discussed OWL and SPARQL.

SPARQL, is a query language and data access protocol for the Semantic Web. SPARQL is defined in terms of the W3C's RDF data model and will work for any data source that can be mapped into RDF.

OWL:• OWL stands for Web Ontology Language
• OWL is built on top of RDF
• OWL is for processing information on the web
• OWL was designed to be interpreted by computers
• OWL was not designed for being read by people
• OWL is written in XML
• OWL has three sublanguages
• OWL is a W3C standard

OWL is a part of the "Semantic Web Vision" - a future where:
• Web information has exact meaning
• Web information can be processed by computers
• Computers can integrate information from the web
