NAME
       RDFStore::Resource - An RDF Resource Node implementation

SYNOPSIS
	       use RDFStore::Resource;
	       my $resource = new RDFStore::Resource("http://pen.jrc.it/index.html");
	       my $resource1 = new RDFStore::Resource("http://pen.jrc.it/","index.html");

	       print $resource->toString." is ";
	       print "not"
		       unless $resource->equals($resource1);
	       print " equal to	".$resource1->toString."\n";

	       # or from URI object
	       use URI;
	       $resource = new RDFStore::Resource("http://www.w3.org/1999/02/22-rdf-syntax-ns#","Description");
	       $resource1 = new	RDFStore::Resource( new	URI("http://www.w3.org/1999/02/22-rdf-syntax-ns#Description") );

	       print $resource->toString." is ";
	       print "not"
		       unless $resource->equals($resource1);
	       print " equal to	".$resource1->toString."\n";

	       my $resource = new RDFStore::Resource([ a,{ d =>	'value'}, [ 1,2,3] ]);

	       print $resource->toString." is ";
	       print "not"
		       unless($resource->isbNode);
	       print " anonymous\n";

DESCRIPTION
       An RDF Resource Node implementation which support the so	called
       anonymous-resources or bNodes (blankNodes)

METHODS
       new ( LOCALNAME_NAMESPACE [, LOCALNAME ]	)
	   This	is a class method, the constructor for RDFStore::Resource. In
	   case	the method is called with a single perl	scalar as parameter a
	   new RDF Resource is created with the	string passed as indentifier
	   (LOCALNAME);	a fully	qualified RDF resource can be constructed by
	   invoching the constructor with two paramters	where the former is
	   the NAMESPACE and the latter	is the LOCALNAME. By RDF definition we
	   assume that LOCALNAME can not be undefined. If LOCALNAME is a perl
	   reference the new Resource is flagged as anonymous-resource or
	   bNode :)

	   bNodes can be created either	passing	a perl reference to the
	   constructor or by using the RDFStore::NodeFactory(3)	createbNode()
	   or createAnonymousResource()	methods; the latter is actually
	   setting the RDFStore::Resource internal bNode flag.

       isAnonymous
	   Return true if the RDF Resource is anonymous	or is a	bNode

       isbNode
	   Return true if the RDF Resource is anonymous	or is a	bNode

       getURI
	   Return the URI identifing the RDF Resource; an undefined values i
	   returned if the node	is blank or anonymous.

       getNamespace
	   Return the Namespace	identifier of the Resource

       getLocalName
	   Return the LocalName	identifier of the Resource; if the Resource is
	   anonymous (bNode) the Storable(3) representation of the label is
	   returned instead. This will allow to	distinguish bNodes between
	   normal resources and	give them a kind of unique identity. NOTE See
	   RDFStore::Model(3) to see how actually bNodes are being stored and
	   retrieved in	RDFStore(3).

       getLabel
	   Return the URI identifing the RDF Resource.

       equals
	   Compare two RDF Resources either textual

       getNodeID
	   Return the rdf:nodeID if the	Resource is anonymous (bNode).

       getbNode
	   Return the bNode conent.
