<h4 id="fourth-public-working-draft">Fourth Public Working Draft</h4>
<p>This is the fourth public release of the PROV-DM document. Following feedback, the Working Group has decided to reorganize this document substantially, separating the data model from its contraints and the notation used to illustrate it. The PROV-DM release is synchronized with the release of the PROV-O, PROV-PRIMER, PROV-N, and PROV-CONSTRAINTS documents. We are now clarifying the entry path to the PROV family of specifications.</p>
