+This document provides a non-normative overview of the PROV Family of Documents and provides a roadmap to using these these documents.
Provenance is information about entities, activities, and people involved in producing a piece of data or thing, which can be used
-to form assessments about its quality, reliability or trustworthiness. The goal of PROV is to enable the wide publication and interchange of provenance on the Web and other information systems. PROV enables one to represent and interchange provenance information using widely available formats such as RDF and XML. In addition, it provides specifications for accessing provenance information and validating it.
+to form assessments about its quality, reliability or trustworthiness. The goal of PROV is to enable the wide publication and interchange of provenance on the Web and other information systems. PROV enables one to represent and interchange provenance information using widely available formats such as RDF and XML. In addition, it provides definitions for accessing provenance information, validating it, and mapping to Dublin Core.
+
+<p>
+Below is the organization of PROV. At its core is a conceptual data model, which defines a common vocabulary used to describe provenance. This instantiated by various serializations. These serializations are what are used by implementations to interchange provenance. To help developers and user create valid provenance, a set of constraints are defined, which can be used to create provenance validators. Finally, to further support the interchange of provenance, additional definitions are provided defining protocols for locating and accessing provenance as well as defining how to interoperate with the widely used Dublin Core vocabulary.

<h2>Roadmap</h2>
+PROV consists of 10 documents (including this one) . In order to use PROV, one need not be familiar with all of these documents. Indeed, PROV was specifically designed so that simple usage would always be compatible with more advanced usage scenarios. To help navigate PROV, each document is broadly classified as being intended for a specific audience.
+
+<ol>
+<li> Users - this audience wants to understand PROV and use applications that support PROV.
+<li> Developers - this audience wants to develop or build applications that create and consume provenance using PROV.
+<li> Advanced - this audience aims to create validators, new PROV serializations, or other advanced provenance systems.

+<h2>Additional Information</h2>
+In addition, to these specifications, the PROV FAQ page addresses common questions as well as sets PROV in a broader context. This page is continually updated. Working group members have also given several tutorials about PROV including hands-on exercises, these may be a useful place to start. In addition, one can find a variety of blog posts and web pages on PROV - a short list can be found here.
-</ul>
-<h4>How to read the PROV Family of Documentation</h4>
-<ul>
-<li>The primer is the entry point to PROV offering an introduction to the provenance model.</li>
-<li>The Linked Data and Semantic Web community should focus on PROV-O defining PROV classes and properties specified in an OWL2 ontology. For further details, PROV-DM and PROV-CONSTRAINTS specify the constraints applicable to the data model, and its interpretation. </li>
-<li>Developers seeking to retrieve or publish provenance should focus on PROV-AQ.</li>
-<li>Readers seeking to implement other PROV serializations
-should focus on PROV-DM and PROV-CONSTRAINTS. PROV-O and PROV-N offer examples of mapping to RDF and text, respectively.</li>
-</ul>
+Finally, the simplest way to use PROV is through one of the many applications that support it.
