RDF (Resource Description Framework) and metadata interfaces.
This module provides interfaces for storing and accessing metadata in Resource Description Framework format. The API consists of two main parts: the RDF data model and the ODF document integration.
The RDF data model describes graphs of statements. The nodes in the graph are of type rdf::XNode, which has several subtypes: rdf::XResource, rdf::XBlankNode, rdf::XURI and rdf::XLiteral. Statements are then triples of nodes, and have type rdf::Statement.
The main part of the RDF data model is the rdf::XRepository, 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 rdf::XNamedGraph.
Documents that support metadata implement the interfaces rdf::XRepositorySupplier and rdf::XDocumentMetadataAccess. Furthermore, all elements of ODF documents that may have metadata attached implement the interface rdf::XMetadatable.
