The WebID should be a URI which when dereferenced returns a representation whose description uniquely identifies the Agent who is the controller of a public key. In our example the WebID refers to Bob. A WebID is usually a URL with a #tag, as the meaning of such a URL is defined in the document refered to by the WebID URL without the #tag .

Dereferencing the WebID should return the Profile Page in one of a number of formats. The Server must publish the document in at least the RDFa [RDFA-CORE] serialization format or in Turtle [TURTLE-TR]. The document may be published in a number of other RDF serialization formats, such as RDF/XML [RDF-PRIMER], or N3 [N3]. Any other serializations that intend to be used by the WebID Protocol must be transformable automatically and in a standard manner to an RDF Graph, using technologies such as GRDDL [GRDDL-PRIMER].

When de-referenced (or looked up) this kind of URI returns a document that uniquely describes its referent -- the denoted Agent. In our example, a WebID *denotes* Bob, it takes the form of an HTTP URL with a #tag or fragment identifier, and returns an RDF document that describes Bob.
