 <p>This section introduces provenance concepts with informal explanations and illustrative
 examples. PROV distinguishes  <em>core structures</em>, forming the essence of  provenance, from <em>extended structures</em> catering for more specific uses of provenance.  Core and extended structures are respectively presented in <a href="#core-structures">Section 2.1</a> and <a href="#section-extended-structures">Section 2.2</a>. Furthermore, the PROV data model is organized according to components, which form thematic groupings of concepts (see <a href="#section-overview-components">Section 2.3</a>). A <em>provenance description</em> is an instance of  a core and extended provenance structure described below.

The purpose of this section is to put these concepts into practice in order to express the provenance of some document published on the Web.  
 With this realistic example, PROV concepts are  composed together,  and a graphical illustration shows a provenance description forming a directed graph, rooted at the entity we want to explain the provenance of, and pointing to the entities, activities, and agents it depended on. This example also shows that, sometimes, multiple provenance descriptions about the same entity can co-exist, which then justifies the need for provenance of provenance.</p>
