RDF is the language for describing resources and contents in the semantic web. In the semantic web RDF is used to describe resources on the web. Resources are addressed by a unique URI. A URI looks like a normal Internet URL.

Look at the following fragment of a RDF file:

The semantic web describes relations between concepts. For example:

A isPartOf B
B hasType C
C isMemberOf D

Also properties of concepts can be described:

A hasAge X
B hasSize X
C has Length X

Where in this case X could be of type Integer.
