Pre-defined URIS and Nodes in the RDF namespaces.

<para>
This module presents RDF concepts from either the RDF namespace
<ulink url="http://www.w3.org/1999/02/22-rdf-syntax-ns#">http://www.w3.org/1999/02/22-rdf-syntax-ns#</ulink>
or the RDF Schema namespace
<ulink url="http://www.w3.org/2000/01/rdf-schema#">http://www.w3.org/2000/01/rdf-schema#</ulink>
</para>

<para>
This list includes both syntax terms such as
<literal>rdf:li</literal> as well as model concepts (RDF
properties or classes) such as <literal>rdf:Seq</literal>
</para>

<para>
These are used in code using two lists of macros to get fast
pointers to #librdf_node or #librdf_uri objects for the concept.
These should be copied with the appropriate #librdf_node
or #librdf_uri class copy constructors before use.
</para>

<example>
<title>Using macros to get a node and URI for an RDF concept</title>
<programlisting>
  #include &lt;redland.h&gt;
  ...

  librdf_node* n=librdf_new_node_from_node(LIBRDF_MS_value);

  librdf_uri* u=librdf_new_uri_from_uri(LIBRDF_MS_value_URI);
