+ PROV-DM is a domain-agnostic model, but with clear extensibility points allowing further domain-specific and
+application-specific extensions to be defined.
+The PROV data model is structued according to six components covering various aspects of provenance:
+<ol>
+<li> component 1: entities and activities, and the time at which they were created, used, or ended;
+<li> component 2: agents bearing responsibility for entities that were generated and actities that happened;
+<li> component 3: derivations between entities;
+<li> component 4: properties to link entities that refer to a same thing;
+<li> component 5: collections of entities, whose provenance can itself be tracked;
+<li> component 6: a simple annotation mechanism.
+</ol>
+</p>
<p>This specification intentionally presents the key concepts of the PROV Data Model, without drilling down into all its subtleties. Using these key concepts, it becomes possible to write useful provenance assertions very quickly, and publish or embed them along side the data they relate to. </p>
-<p>However, if data changes, then it is challenging to express its provenance precisely, like it would be for any other form of metadata. To address this challenge, a <em>refinement</em> is proposed to enrich simple provenance, with extra-descriptions that help qualify the specific subject of provenance and provenance itself, with attributes and interval, intended to satisfy a comprehensive set of constraints. These aspects are covered in the companion specification [[PROV-DM-CONSTRAINTS]].
