35   * creating and returning RDFReader's, it also provides methods
36   * for creating a reader, invoking a read method on it and then
37   * shuting it down.</p>
38   *
39   * <p>The factory will create an appropriate reader for the particular
40   *   serialization language being read.  Predefined languages include:</p>
41   * <ul>
42   * <li>RDF/XML - default</li>
43   * <li>RDF/XML-ABBREV</li>
44   * <li>N-TRIPLE</li>
45   * <li>N3</li>
46   * </ul>
47   *<p>System wide defaults for classes to use as readers for these languages
48   *are defined.  These defaults may be overwridden by setting a system property
49   *with a name of the form com.hp.hpl.jena.readers.<lang> to the class
50   *name.</p>
