       The <strong>third</strong> category allows further description of Entities. The property <a href="#value" class="qname">prov:value</a> holds a literal value for the Entity. For example, the <span class="repeated">prov:value</span> of a quote could be a string of the sentences stated, or the <span class="repeated">prov:value</span> of an Entity involved in a numeric calculation could be the xsd:integer four.
 		 The property <a href="#atLocation" class="qname">prov:atLocation</a> can be used to describe the <a href="#Location" class="qname">prov:Location</a> of any

       The properties used to describe instances of <span class="repeated">prov:Location</span> are outside the scope of PROV-O;

       Similarly to how Activities have start and end times, an Entity may be bound by points in time for which it was generated or is no longer usable. 
 The properties <a href="#generatedAtTime" class="qname">prov:generatedAtTime</a> and <a href="#invalidatedAtTime" class="qname">prov:invalidatedAtTime</a> can be used to bound the starting and ending moments of an Entity's existence. The Activities that led to the generation or invalidation of an Entity can be provided using <span class="repeated">prov:wasGeneratedBy</span> and <a href="#wasInvalidatedBy" class="qname">prov:wasInvalidatedBy</a>, respectively. 
 <a href="#generated" class="qname">prov:generated</a> and <a href="#invalidated" class="qname">prov:invalidated</a> are the inverses of <span class="repeated">prov:wasGeneratedBy</span> and <span class="repeated">prov:wasInvalidatedBy</span>, respectively, and are defined to facilitate Activity-centric in addition to Entity-centric modeling.
