019/**
020 * Subclass of {@link RdfParser} for parsing RDF/JSON into POJOs.
021 *
022 * <p>
023 * Accepts RDF in JSON notation and converts it to Java beans, maps, collections, and primitive types.
024 * Date/time literals are parsed via ISO 8601.
025 *
026 * <h5 class='figure'>Examples:</h5>
027 * <p class='bjava'>
028 *    <jc>// Parse RDF/JSON string into a bean.</jc>
029 *    String <jv>rdfJson</jv> = ...;  <jc>// RDF/JSON content</jc>
030 *    Person <jv>person</jv> = RdfJsonParser.<jsf>DEFAULT</jsf>.read(<jv>rdfJson</jv>, Person.<jk>class</jk>);
031 * </p>
032 * <p class='bjava'>
033 *    <jc>// Or use the RdfJson marshaller for convenience.</jc>
034 *    Person <jv>person</jv> = RdfJson.<jsm>to</jsm>(<jv>rdfJson</jv>, Person.<jk>class</jk>);
035 * </p>
036 * <p class='bjava'>
037 *    <jc>// Parse into a list of beans.</jc>
038 *    List&lt;Person&gt; <jv>people</jv> = RdfJsonParser.<jsf>DEFAULT</jsf>.read(<jv>rdfJson</jv>, List.<jk>class</jk>, Person.<jk>class</jk>);
039 * </p>
040 * <p class='bjava'>
041 *    <jc>// Custom parser with swaps.</jc>
042 *    RdfJsonParser <jv>p</jv> = RdfJsonParser.create().swaps(DateSwap.<jk>class</jk>).build();
043 *    MyBean <jv>bean</jv> = <jv>p</jv>.read(<jv>rdfJson</jv>, MyBean.<jk>class</jk>);
044 * </p>
