+
+
+<p>
+PROV-DM, the PROV<span class="insert"> conceptual</span> data model, is a data model for provenance that describes
+the entities, people and activities involved in
+producing a piece of data or thing. 
+PROV-DM <span class="insert">distinguishes core structures, forming the essence of provenance descriptions, from
+extended structures catering for more advanced uses of provenance. 
+PROV-DM </span>is <span class="delete">structured</span><span class="insert">organized</span> in six components,<span class="insert"> respectively</span> dealing with: 
+(1) entities and activities, and the time at which they were created, used, or ended;
+(2) agents bearing responsibility for entities that were generated and activities that happened;
+(3) derivations of entities from entities;
+(4) properties to link entities that refer to the same thing;
+(5) <span class="insert">a notion of bundle, a mechanism to support provenance of provenance; and,
+(6) </span>collections forming a logical structure for its <span class="delete">members;
+(6) a simple annotation mechanism.</span><span class="insert">members.</span>
+</p>
+
+<p>To provide examples of the PROV data model, the PROV notation (PROV-N) is introduced: aimed at human consumption, PROV-N allows serializations of PROV
+instances to be created in a compact manner. PROV-N facilitates the
+mapping of the PROV data model to concrete syntax, and is used as the basis for a
+formal semantics of PROV.  The purpose of this document is to define the PROV-N notation.

+This document is part of the PROV family of specifications, a set of specifications defining various aspects that are necessary to achieve the vision of inter-operable
+interchange of provenance information in heterogeneous environments such as the Web.  The specifications are:
+<ul>
+<li> PROV-DM, the PROV data model for provenance;</li>
+<li> PROV-CONSTRAINTS, a set of constraints applying to the PROV data model;</li>
+<li> PROV-N, a notation for provenance aimed at human consumption  (this document);</li>
+<li> PROV-O, the PROV ontology, an OWL-RL ontology allowing the mapping of PROV to RDF;</li>
+<li> PROV-AQ, the mechanisms for accessing and querying provenance; </li>
+<li> PROV-PRIMER, a primer for the PROV data model;</li>
+<li> PROV-SEM, a formal semantics for the PROV data model;</li>
+<li> PROV-XML, an XML schema for the PROV data model.</li>
+</ul>
+<h4 id="how-to-read-the-prov-family-of-specifications">How to read the PROV Family of Specifications</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 OWL-RL ontology. For further details, PROV-DM and PROV-CONSTRAINTS specify the constraints applicable to the data model, and its interpretation. PROV-SEM provides a mathematical semantics.</li>
+<li>The XML community should focus on PROV-XML defining an XML schema for PROV. Further details can also be found in PROV-DM, PROV-CONSTRAINTS, and PROV-SEM.</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, PROV-N, PROV-XML offer examples of mapping to RDF, text, and XML, respectively.</li>
+</ul>
+
+
+
+<span class="delete">First Public Working Draft</span>
+ 
+<p>This <span class="delete">is the first public release of the PROV-N
+document. Following feedback, the Working Group has decided to
+reorganize the PROV-DM document substantially, separating the data model,
+from its constraints, and the notation used to illustrate it. The
+PROV-N release is synchronized with the release of the PROV-DM, PROV-O,
+PROV-PRIMER, and PROV-CONSTRAINTS documents.

+
+<p> Provenance is<span class="delete"> defined as</span> a record that describes the people,
+institutions, entities, and activities, involved in producing,
+influencing, or delivering a piece of data or a thing in the world.  Two
+companion specifications respectively define PROV-DM, a data model for
+provenance, allowing provenance descriptions to be expressed  [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>]  and a set of constraints that provenance descriptions are expected to satisfy   [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-CONSTRAINTS">PROV-CONSTRAINTS</a></cite>].

+<div id="purpose" class="section"> 
+<h3><span class="secno">1.1 </span>Purpose of this Document and target audience</h3>
+
+A key goal of PROV is the specification of a machine-processable data model for provenance. However, communicating provenance between humans is also important when teaching, illustrating, formalizing, and discussing provenance-related issues. 
+
+
+
+With these two requirements in mind, this document introduces PROV-N, a syntax notation designed to  write instances of the PROV data model according to the following design principles:
+<ul>
+<li>Technology independence. PROV-N provides a simple syntax that can be mapped to several technologies.
+
+</li><li>Human readability. PROV-N follows a functional syntax style that is meant to be easily human-readable so it can be used in illustrative examples, such as those presented in the PROV documents suite;
+
+</li><li>Formality. PROV-N is defined through a formal grammar amenable to be used with parser generators.
+
+ </li></ul>
+  
+PROV-N has several known uses:
+<ul>
+<li> It is the notation used in the examples found in  [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>], as well as in the definition of PROV constraints [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-CONSTRAINTS">PROV-CONSTRAINTS</a></cite>]; </li>
+<li>  It is a source language for the encoding of PROV data model instances into a variety of target languages, including amongst others  RDF [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-RDF">PROV-RDF</a></cite>] and XML [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-XML">PROV-XML</a></cite>]; </li>
+<li> It provides the basis for a formal semantics of the PROV data model  [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-SEM">PROV-SEM</a></cite>], in which an interpretation is given to each element of the PROV-N language.
+</li></ul>
+
+<p>This document introduces the PROV-N grammar along with examples of its usage.</p>
+<p>Its target audience is twofold:
+</p><ul>
+<li>Developers of provenance management applications, as well as implementors of new PROV data model encodings, and thus in particular of PROV-N parsers. These readers may be interested in the entire structure of the grammar, starting from the top level nonterminal <span class="delete">container</span> 
+<a class="grammarRef" href="#prod-bundle"><span class="insert">bundle</span></a>.</li>
+<li>Readers of the  [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-DM">PROV-DM</a></cite>] and of  [<cite><a class="bibref" rel="biblioentry" href="#bib-PROV-CONSTRAINTS">PROV-CONSTRAINTS</a></cite>] documents, who are interested in the details of the formal language underpinning the notation used in the examples and in the definition of the constraints. Those readers may find the  <a class="grammarRef" href="#prod-expression">expression</a> nonterminal a useful entry point into the grammar.</li>

+<h3><span class="secno">2.1 </span>Functional-style Syntax</h3>
+
+<p> PROV-N adopts a functional-style syntax consisting of a predicate name and an ordered list of terms.
+All PROV data model relations involve two primary elements, the <em>subject</em> and the <em>object</em>, in this order. Furthermore, some expressions also admit additional elements that further characterize it.
+</p><div class="anexample" id="example_1" data-count="1"><div class="anexampleTitle"><a class="internalDFN" href="#example_1"><span class="insert">Example 1</span></a></div>
+The following expression should be read as "<span class="name">e2</span> was derived from <span class="name">e1</span>". Here <span class="name">e2</span> is the subject, and  <span class="name">e1</span> is the object.

+<h3><span class="secno">2.2 </span>EBNF Grammar</h3>
+
+<p>The grammar is specified using the Extended  Backus-Naur Form (EBNF) notation.</p>
+<div class="grammar">
+  Each production rule (or <dfn id="dfn-production">production</dfn>, for short) in the grammar defines one non-terminal symbol <span class="nonterminal">E</span>, in the following form:<p></p>
+
+<span class="nonterminal">E</span>&nbsp;::= <em>term</em>
+
+<p>Within the term on the right-hand side of a rule, the following terms are used to match strings of one or more characters:
+</p><ul>
+<li> 
+<span class="nonterminal">E</span>: matches term satisfying rule for symbol E.
+</li>
+
+<li> 
+<span class="name">abc</span>: matches the literal string inside the single quotes.

+</li>
+
+<li> 
+<span class="plus"><em>term</em></span>: matches one or more occurrences of <em>term</em>.

+<span class="choice"><em>term</em> | <em>term</em></span>: matches one of the two <em>terms</em>.

+
+The grammar is centered on nonterminals for various types of <a class="grammarRef" href="#prod-expression">expression</a>.

+<div id="prov-n-optionals" class="section"> 
+<h3><span class="secno">2.3 </span>Optional terms in expressions</h3>
+
+Some terms in an expression may be optional. For example:
+
+<div class="anexample" id="example_3" data-count="3"><div class="anexampleTitle"><a class="internalDFN" href="#example_3"><span class="insert">Example 3</span></a></div>
+<pre class="codeexample">wasDerivedFrom(e2, e1, a, g2, u1)
+wasDerivedFrom(e2, e1)
+</pre>
+In a derivation expression, the activity, generation, and usage are optional terms. They are specified in the first derivation, but not in the second.
+</div>
+
+<div class="anexample" id="example_4" data-count="4"><div class="anexampleTitle"><a class="internalDFN" href="#example_4"><span class="insert">Example 4</span></a></div>
+<pre class="codeexample">activity(a2, 2011-11-16T16:00:00, 2011-11-16T16:00:01)
+activity(a1)
+</pre>
+The start and end times for Activity <span class="name">a1</span> are optional. They are specified in the first expression, but not in the second.
+</div>
+
+<p>The general rule for optionals is that, if <em>none</em> of the optionals are used in the expression, then they are simply omitted, resulting in a simpler expression as in the examples above.</p>
+However, it may be the case that only some of the optional terms are omitted. Because the position of the terms in the expression matters, an additional marker must be used to indicate that a particular term is not available. The symbol  <span class="name"><span class="delete">-</span><span class="insert">'-'</span></span> is used for this purpose.
+
+<div class="anexample" id="example_5" data-count="5"><div class="anexampleTitle"><a class="internalDFN" href="#example_5"><span class="insert">Example 5</span></a></div>
+<p>In the first expression below, all optionals are specified. However in the <span class="delete">second,</span><span class="insert">second and third,</span> only <span class="delete">the last </span>one <span class="insert">optional </span>is specified, forcing the use of the marker for the missing terms.<span class="delete"> In the last, no marker is necessary because all </span><span class="delete">remaining</span><span class="delete"> optionals after </span><span class="delete">a</span><span class="delete"> are missing.
+
+</span> 
+
+</p><pre class="codeexample">wasDerivedFrom(e2, e1, a, g2, u1)
+wasDerivedFrom(e2, e1, -, -, u1)
+wasDerivedFrom(e2, e1, <span class="delete">a)</span><span class="insert">a, -, -)</span>
+</pre>
+</div>
+Note that the more succinct form is just shorthand for a complete expression with all the markers specified:
+<div class="anexample" id="example_6" data-count="6"><div class="anexampleTitle"><a class="internalDFN" href="#example_6"><span class="insert">Example 6</span></a></div>

+
+<div id="prov-n-standard-terms" class="section"> 
+<h3><span class="secno">2.4 </span>Identifiers and attributes</h3>
+
+<p>Most expressions defined in the grammar include the use of two terms: an identifier <span class="insert">and a set of attribute-value pairs, delimited by square brackets. Identifiers are optional except </span>for <span class="delete">the predicate,</span><span class="insert">Entities, Activites,</span> and <span class="insert">Agents. Identifiers are always the first term in any expression. By convention, optional identifiers are separated using </span>a <span class="insert">semi-colon ';'. This makes it possible to completely omit an optional identifier with no ambiguity arising. Also, if the </span>set of attribute-value <span class="delete">pairs, delimited by square brackets.
