 An nsIRDFResource is an object that has unique identity in the 
 RDF data model. The object's identity is determined by its URI.
[scriptable, uuid(fb9686a7-719a-49dc-9107-10dea5739341)]
interface nsIRDFResource : nsIRDFNode

Attributes

 The single-byte string value of the resource.
 @note THIS IS OBSOLETE. C++ should use GetValueConst and script
       should use .valueUTF8
readonly attribute string Value 
 The UTF-8 URI of the resource.
readonly attribute AUTF8String ValueUTF8

Methods

 Determine if the resource has the given URI.
boolean EqualsString(in string aURI) 
 Retrieve the "delegate" object for this resource. A resource
 may have several delegate objects, each of whose lifetimes is
 bound to the life of the resource object.

 This method will return the delegate for the given key after
 QueryInterface()-ing it to the requested IID.

 If no delegate exists for the specified key, this method will
 attempt to create one using the component manager. Specifically,
 it will combine aKey with the resource's URI scheme to produce
 a ContractID as follows:

   component:/rdf/delegate-factory/[key]/[scheme]

 This ContractID will be used to locate a factory using the
 FindFactory() method of nsIComponentManager. If the nsIFactory
 exists, it will be used to create a "delegate factory"; that
 is, an object that supports nsIRDFDelegateFactory. The delegate
 factory will be used to construct the delegate object.
void GetDelegate(in string aKey, in nsIIDRef aIID, [iid_is(aIID), retval] out nsQIResult aResult) 
 An unscriptable version used to avoid a string copy. Meant
 for use as a performance optimization. The string is encoded
 in UTF-8.
[noscript] void GetValueConst([shared] out string aConstValue) 
 This method is called by the nsIRDFService after constructing
 a resource object to initialize it's URI. You would not normally
 call this method directly
void Init(in string uri) 
 Force a delegate to be "unbound" from the resource.

 Normally, a delegate object's lifetime will be identical to
 that of the resource to which it is bound; this method allows a
 delegate to unlink itself from an RDF resource prematurely.
void ReleaseDelegate(in string aKey)
