The PROV-DM release is synchronized with the release of the PROV-O, PROV-PRIMER, PROV-N, <span class="insert">and </span>PROV-DM-CONSTRAINTS documents. We are now <span class="delete">making clear what</span><span class="insert">clarifying</span> the entry path to the PROV family of <span class="delete">specifications is.</span><span class="insert">specifications.</span></p>

+<p>The attribute <dfn title="dfn-value"><span class="name">prov:value</span></dfn> provides a <a title="value">Value</a> associated with an entity.</p>
+
+
+<p>The attribute <span class="name">prov:value</span> is an OPTIONAL attribute of entity. The value associated with the attribute <span class="name">prov:value</span> MUST be a PROV-DM <a title="value">Value</a>. The attribute <span class="name">prov:value</span> MAY occur at most once in a set of attribute-value pairs.</p>

+<div class="anexample">
+<p>The following example illustrates the provenance of the number <span class="name">4</span> obtained by an activity that computed the length of an input string <span class="name">"abcd"</span>.
+The input and the output are expressed as entities <span class="name">ex:in</span> and <span class="name">ex:out</span>, respectively. They each have a <span class="name">prov:value</span> attribute associated with the corresponding value.
