| * Commons RDF, a common library of RDF 1.1 concepts. |
| * <p> |
| * The core <a href="http://www.w3.org/TR/rdf11-concepts/">RDF 1.1 concepts</a> |
| * are represented by corresponding interfaces: |
| * <p> |
| * A {@link org.apache.commons.rdf.api.Graph} is a collection of |
| * {@link org.apache.commons.rdf.api.Triple}s, which have a <em>subject</em>, |
| * <em>predicate</em> and <em>object</em> 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}. |
| * <p> |
| * Implementations of this API should provide an |
| * {@link org.apache.commons.rdf.api.RDF} to facilitate creation of these |
| * objects. |
| * <p> |
| * 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)}). |
| * <p> |
| * {@link org.apache.commons.rdf.api.RDFSyntax} enumerates the W3C standard RDF |
| * 1.1 syntaxes and their media types. |
| * <p> |
| * For further documentation and contact details, see the |
| * <a href="http://commonsrdf.incubator.apache.org/">Commons RDF</a> web site. |
