*Summary*
--------
+ module com.sun.star.rdf
*Description*
-------------
there is a new API for handling RDF data:
/** RDF (Resource Description Framework) and metadata interfaces.
<p>
This module provides interfaces for storing and accessing metadata
in <a href="http://www.w3.org/RDF/";>Resource Description Framework</a>
format.
The API consists of two main parts: the RDF data model and the ODF
document integration.
</p>
<p>
The <a href="http://www.w3.org/TR/rdf-concepts/";>RDF data model</a>
describes graphs of statements.
The nodes in the graph are of type <type scope="rdf">XNode</type>,
which has several subtypes: <type scope="rdf">XResource</type>,
<type scope="rdf">XBlankNode</type>,
<type scope="rdf">XURI</type> and <type scope="rdf">XLiteral</type>.
Statements are then triples of nodes, and have type
<type scope="rdf">Statement</type>.
</p>
<p>
The main part of the RDF data model is the
<type scope="rdf">XRepository</type>, which consists of a set of
graphs.
The repository allows for importing/exporting graphs from/to files,
as well as querying the contents of the repository.
The type of the graphs is <type scope="rdf">XNamedGraph</type>.
</p>
<p>
Documents that support metadata implement the interfaces
<type scope="rdf">XRepositorySupplier</type> and
<type scope="rdf">XDocumentMetadataAccess</type>.
Furthermore, all elements of ODF documents that may have metadata
attached
implement the interface <type scope="rdf">XMetadatable</type>.
</p>
