Suitability of RDF - RDF

The Resource Description Framework

The Resource Description Framework (RDF) is a collection of W3C specifications that serves as a data model for metadata of web resources. RDF introduces the notion of triples of the form (s,p,o) where s is the "subject", that is the resource on the web being described, p stands for a well defined property and o is an object that can be either a web resource or a literal value. Both the subject s and the property p are web resources identified by their URI. Here is an example of a triple:

( <http://www.youtube.com/watch?v=M_bvT-DGcWw>, <http://music.org/#band>, <http://music.org/#pinkfloyd> )

Resources are identified by a URI which need not be a URL (web address). The term "Web Resources" refers to information that can be found on the web, including but not restricted to web pages. RDF exists in various equivalent representations: RDF/XML which is XML-formatted, RDF/Turtle, N-Triples and other.
