+This section provides an introduction to the PROV data model by
+overviewing a set of concepts underpinning provenance descriptions
+that a novice reader would write in a first instance.  In Sections 2.1
+to 2.4, these concepts are described in natural language and
+illustrated by small examples.  Since PROV-DM is a conceptual data
+model, Section 2.5 maps the concepts to various types and relations,
+which are illustrated graphically in
+a <a href="#prov-dm-overview">simplified UML diagram</a>.  Section 2.6
+then summarizes the PROV notation allowing instances of PROV-DM to be
+written down.
