         If <a class="internalDFN">provenance information</a> is a resource that can be accessed using web retrieval, one needs to know its <a class="internalDFN">provenance-URI</a> to dereference.  If this is known in advance, there is nothing more to specify.  If a provenance-URI is not known then a mechanism to discover one must be based on information that is available to the would-be accessor. Likewise, provenance information may be exposed by a service, in which case, the <a class="internalDFN">service-URI</a> needs to be known.

           For a resource accessible using HTTP, provenance information may be indicated using an HTTP <code>Link</code> header field, as defined by <a href="http://tools.ietf.org/html/rfc5988">Web Linking (RFC 5988)</a> [[LINK-REL]].  The <code>Link</code> header field is included in the HTTP response to a GET or HEAD operation (other HTTP operations are not excluded, but are not considered here).

           For a document presented as HTML or XHTML, without regard for how it has been obtained, provenance information may be associated with a resource by adding a <code>&lt;link&gt;</code> element to the HTML <code>&lt;head&gt;</code> section.
