obsolete_date_created true SEPIO creates a relation separate from existing PAV and PROV relations (e.g. pav:createdOn) which are too specific about whether a relation refers to the date on which the abstract information content was created, or when it was serialized and documented as a concrete digital artifact or resource with a particular format. Consider: 1. http://purl.org/dc/terms/created 2. http://purl.org/pav/createdOn ! Created on Def: The date of creation of the resource representation. The agents responsible can be indicated with pav:createdBy. This property is normally used in a functional way, indicating the time of creation, although PAV does not formally restrict this. pav:lastUpdateOn can be used to indicate minor updates that did not affect the creating date. 3. prov:generatedAtTime: The time at which an entity was completely created and is available for use. created_on
