019/**
020 * Subclass of {@link RdfParser} for parsing N3 (Notation3) into POJOs.
021 *
022 * <p>
023 * Accepts RDF in Notation3 format and converts it to Java beans, maps, collections, and primitive
024 * types. Date/time literals are parsed via ISO 8601.
025 *
026 * <h5 class='figure'>Examples:</h5>
027 * <p class='bjava'>
028 *    <jc>// Parse N3 string into a bean.</jc>
029 *    String <jv>n3</jv> = ...;  <jc>// N3 content</jc>
030 *    Person <jv>person</jv> = N3Parser.<jsf>DEFAULT</jsf>.read(<jv>n3</jv>, Person.<jk>class</jk>);
031 * </p>
032 * <p class='bjava'>
033 *    <jc>// Or use the N3 marshaller for convenience.</jc>
034 *    Person <jv>person</jv> = N3.<jsf>DEFAULT</jsf>.read(<jv>n3</jv>, Person.<jk>class</jk>);
035 * </p>
036 * <p class='bjava'>
037 *    <jc>// Custom parser with swaps.</jc>
038 *    N3Parser <jv>p</jv> = N3Parser.create().swaps(DateSwap.<jk>class</jk>).build();
039 *    MyBean <jv>bean</jv> = <jv>p</jv>.read(<jv>n3</jv>, MyBean.<jk>class</jk>);
040 * </p>
041 *
042 * <h5 class='figure'>Example input (bean with name/age):</h5>
043 * <p class='bcode'>
044 *    @prefix j: &lt;...&gt; .
045 *    &lt;...&gt; a j:Person ; j:name "Alice" ; j:age 30 .
046 * </p>
047 *
048 * <h5 class='figure'>Complex (nested address + array):</h5>
049 * <p class='bcode'>
050 *    @prefix j: &lt;...&gt; .
051 *    &lt;...&gt; a j:Person ; j:name "Alice" ; j:age 30 ;
052 *       j:address &lt;.../address&gt; ; j:tags &lt;.../tags&gt; .
053 *    &lt;.../address&gt; a j:Address ; j:street "123 Main St" ;
054 *       j:city "Boston" ; j:state "MA" .
