RDF is Designed to be Read by Computers

RDF was designed to provide a common way to describe information so it can be read and understood by computer applications.

RDF descriptions are not designed to be displayed on the web.


RDF is Written in XML

RDF documents are written in XML. The XML language used by RDF is called RDF/XML.

By using XML, RDF information can easily be exchanged between different types of computers using different types of operating systems and application languages.

The RDF language is a part of the W3C’s Semantic Web Activity. W3C’s “Semantic Web Vision” is a future where:

  • Web information has exact meaning
  • Web information can be understood and processed by computers
  • Computers can integrate information from the web
