"So what is the difference?
Documents: XML is a system for defining, validating, and
sharing document formats. XML uses tags to
distinguish document structures, and attributes to
encode extra document information. XML will look very
familiar to those who know about SGML and HTML.
(XML FAQ)
Links: RDF is based on the idea of identifying things
using Web identifiers (called Uniform Resource
Identifiers, or URIs), and describing resources in terms
of simple properties and property values. This enables
RDF to represent simple statements about resources as
a graph of nodes and arcs representing the resources,
and their properties and values.(RDF Primer)"
