W3C Working Group Note 28 August 2008 This version: http://www.w3.org/TR/2008/NOTE-swbp-vocab-pub-20080828/
Elias Torres, a senior software engineer at IBM and a member of several W3C working groups, gives us an overview of the Semantic Web and how RDF and SPARQL are set to become the tools of choice when extracting data from the World Wide Web. In an interview, hosted by Phil Windley, Torres discusses what has happened to this technology in the past, where it is hopefully going in the near future, and what you can do today to take advantage of it. Resource Description Framework (RDF) is a language specification for representing information about resources on the Web. Often referred to as "the triples," RDF relates data objects to one another using a three part syntax of subject, predicate, and object. For example, a car's paint color could be represented as Vehicle.Color.Red.
Up to Design Issues This note is an attempt to answer the question, "Why should I use RDF - why not just XML?". This has been a question which has been around ever since RDF started.
