/**
* Commons RDF, a common library of RDF 1.1 concepts.
*
* The core RDF 1.1 concepts
* are represented by corresponding interfaces:
*
* A {@link org.apache.commons.rdf.api.Graph} is a collection of
* {@link org.apache.commons.rdf.api.Triple}s,
* which have a subject, predicate and object of
* {@link org.apache.commons.rdf.api.RDFTerm}s.
* The three types of RDF terms are {@link org.apache.commons.rdf.api.IRI},
* {@link org.apache.commons.rdf.api.Literal} and
* {@link org.apache.commons.rdf.api.BlankNode}.
*
* Implementations of this API should provide an
* {@link org.apache.commons.rdf.api.RDFTermFactory} to facilitate
* creation of these objects.
*
* All the {@link org.apache.commons.rdf.api.RDFTerm} objects are immutable,
* while a {@link org.apache.commons.rdf.api.Graph}
* MAY be mutable (e.g. support methods like
* {@link org.apache.commons.rdf.api.Graph#add(Triple)}).
*
* {@link org.apache.commons.rdf.api.RDFSyntax} enumerates the
* W3C standard RDF 1.1 syntaxes and their media types.
*
* For further documentation and contact details, see the
* Commons RDF
* web site.
