<p>A key goal of <span class="delete">PROV-DM</span><span class="insert">PROV</span> is the specification of a machine-processable data model for provenance so that applications can retrieve provenance and reason about it. As such, representations of <span class="delete">PROV-DM</span><span class="insert">PROV</span> are available in RDF and XML.

<p>However, it is important to provide instances of provenance for human consumption, as in this document or elsewhere.

In this example, it happens that all entities were already Web resources, with readily available URIs, which we used. We note that some of the resources are public, whereas others have restricted access: provenance statements only make use of their identifiers.

<p>No new mechanism is required to support this requirement. PROV-DM makes the assumption that provenance statements have been bundled up, and named, by some mechanism outside the scope of PROV-DM. For instance, in this case, provenance statements were put in a file and exposed on the Web, respectively at <a href="examples/w3c-publication1.pn">ex:w3c-publication1.pn</a> and <a href="examples/w3c-publication3.pn">ex:w3c-publication3.pn</a>. To express their respective provenance, these resources must be seen as entities, and all the constructs of PROV-DM are now available to characterize their provenance. In the example below, <span class="name">ex:w3c-publication1.pn</span> is attributed to the agent <span class="name">w3:Consortium</span>, whereas <span class="name">ex:w3c-publication3.pn</span> to <span class="name">ex:Simon</span>.
