	Resource Description Framework
RDF

    (RDF) A specification
   being developed in 2000 by the W3C as a foundation for
   processing meta-data regarding resources on the Internet,
   including the World-Wide Web.

   Resource Description Framework data consists of resources
   (nodes), and property/value pairs describing the resource.
   A node is any object which can be pointed to by a URI,
   properties are attributes of the node, and values can be
   either atomic values for the attribute, or other nodes.  For
   example, information about a particular web page (a node),
   might include the property "Author".  The value for the Author
   property could be either a string giving the name of the
   author, or a link to a resource describing the author.

   Resource Description Framework only specifies a mechanism for
   encoding and transferring meta-data.  It does not specify what
   that meta-data should, or can be.  RDF does not, for example,
   define an "Author" attribute.  Sets of properties are defined
   within RDF Vocabularies (or Schemas).  Anynone can create an
   RDF schema, describing a specialized set of properties, by
   creating a resource, referenced by the Schema URI, which
   provides a human- and machine-understandable definition of the
   schema's properties.  The description of a node may include
   properties defined in different schemas.  The properties
   within a resource description are associated with a certain
   schema definition using the XML namespace mechanism.
   Schemas currently being developed include a content screening
   system modeled after PICS, and a bibliographic vocabulary,
   such as the Dublin Core Initiative.
