<p>Provenance records may be offered by several <a class="internalDFN">provider</a>s other than that of the original resource publisher, each with different concerns, and presenting provenance at different locations. It is possible that these different providers may present contradictory provenance.

+ <p class="note">
+ The mechanisms used with HTTP and HTML/RDF are slightly inconsistent in their approach to specifying <code><cite>target-URI</cite></code> values. In HTTP <code>Link:</code> headers, an optional <code>anchor=</code> parameter may be supplied for each such header. In HTML and RDF, separate <code>#has_anchor</code> relations are defined. It was felt that avoiding reinvention of existing mechanisms was more important than being completely consistent. If anchors are processed as described in <a href="#interpreting-provenance-records" class="sectionRef"></a> (3rd paragraph), observable behaviour across all approaches should be consistent.

<h2>Resource accessed by HTTP</h2>

- For a resource accessible using HTTP, a provenance record may be indicated using an HTTP <code>Link</code> header field, as defined by <a href="http://tools.ietf.org/html/rfc5988#section-5" class="externalRef">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).
