+<p>
+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. PROV-DM is the conceptual data model that forms a basis for the <abbr title="World Wide Web Consortium">W3C</abbr> provenance (PROV) family of specifications. It defines a concepts for expressing provenance information enabling interchange. This document introduces an XML schema for the PROV data model (PROV-DM), allowing instances of the PROV data model to be serialized in XML.

+For the purpose of this specification, <dfn id="dfn-provenance" class="internalDFN">provenance</dfn><sup><a class="internalDFN" href="#dfn-provenance"><span class="diamond"> ◊</span></a></sup> is defined as a record that describes the people, institutions, entities, and activities involved in producing, influencing, or delivering a piece of data or a thing.  In particular, the provenance of information is crucial in deciding whether information is to be trusted, how it should be integrated with other diverse information sources, and how to give credit to its originators when reusing it.  In an open and inclusive environment such as the Web, where users find information that is often contradictory or questionable, provenance can help those users to make trust judgements.
+</p>
+
+<p>
+The PROV data model, PROV-DM, presents a generic data model for provenance that allows domain and application specific representations of provenance to be translated into such a data model and <em>interchanged</em> between systems.  Thus, heterogeneous systems can export their native provenance into such a core data model, and applications that need to make sense of provenance can then import it,
+process it, and reason over it.</p>
+
+<p>
+The PROV data model distinguishes <em>core structures</em> from <em>extended structures</em>: core structures form the essence of provenance information, and are commonly found in various domain-specific vocabularies that deal with provenance or similar kinds of information [<cite><a class="bibref" href="#bib-Mappings">Mappings</a></cite>].  Extended structures enhance and refine core structures with more expressive capabilities to cater for more advanced uses of provenance.  The PROV data model, comprising both core and extended structures, is a domain-agnostic model, but with clear extensibility points allowing further domain-specific and application-specific extensions to be defined.
+</p>
+
+<p>
+The PROV data model has a modular design and is structured according to six components covering various facets of provenance:</p>
+<ul>
+<li> component 1: entities and activities, and the time at which they were created, used, or ended;
+</li><li> component 2: derivations of entities from others;
+</li><li> component 3: agents bearing responsibility for entities that were generated and activities that happened;
+</li><li> component 4: bundles, a mechanism to support provenance of provenance;
+</li><li> component 5: properties to link entities that refer to a same thing;
+</li><li> component 6: collections forming a logical structure for its members.
+</li></ul>
+
+<p>
+This specification goal is to provide a succinct definition of the XML form of PROV-DM, thus, we refer the reader to the PROV-DM to provide overall justification and context to the definitions presented here.

+<!--OddPage--><h2><span class="secno">2. </span>XML Schema Design</h2>
+
+<p>Several general design principles and patterns were used in the construction of the PROV XML Schema.</p>
+
+<section id="schema-modularization">
+<h3><span class="secno">2.1 </span>Schema Modularization</h3>
+<p>The PROV-XML schema have been modularized so that extension elements defined in Working Group Notes can be defined in separate schemas.  Elements corresponding to terms defined in the PROV-DM are defined in the <b>prov-core.xsd</b> schema and elements corresponding to terms defined in notes are defined in extension schemas (e.g. <b>prov-dictionary.xsd</b>, <b>prov-links.xsd</b>).  The default schema, <b>prov.xsd</b>, imports <b>prov-core.xsd</b> and all extension schemas developed by the Working Group.  With this modeling all PROV elements, even those defined in Notes, are defined from the default schema.  If the user wishes to leverage a schema that does not include extension elements the user can use schemaLocation to directly reference <b>prov-core.xsd</b>.</p>
+<p>The default schema - <b>prov.xsd</b></p>
+<pre>&lt;?xml version="1.0" encoding="utf-8"?&gt;
+&lt;xs:schema targetNamespace="http://www.w3.org/ns/prov#"
+           xmlns:xs="http://www.w3.org/2001/XMLSchema"
+           xmlns:prov="http://www.w3.org/ns/prov#"
+           elementFormDefault="qualified"
+           attributeFormDefault="unqualified"&gt;
+
+	&lt;xs:include schemaLocation="prov-core.xsd"/&gt;
+	&lt;xs:include schemaLocation="extensions/prov-dictionary.xsd"/&gt;
+	&lt;xs:include schemaLocation="extensions/prov-links.xsd"/&gt;
+
+&lt;/xs:schema&gt;
+</pre>
+<p>Extension schemas import the <b>prov-core.xsd</b> schema and make use of a substitution group on the <code>prov:internalElement</code> to add extension-defined elements to the list of valid PROV elements in a bundle or document.</p>
+<p>The <b>prov-links.xsd</b> extension schema.</p>
+<pre>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
+&lt;xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
+	targetNamespace="http://www.w3.org/ns/prov#" xmlns:prov="http://www.w3.org/ns/prov#"
+	elementFormDefault="qualified"&gt;
+	
+	&lt;xs:include schemaLocation="../prov-core.xsd" /&gt;
+	
+	&lt;xs:complexType name="Mention"&gt;
+		&lt;xs:sequence&gt;
+			&lt;xs:element name="specificEntity" type="prov:IDRef" /&gt;
+			&lt;xs:element name="generalEntity" type="prov:IDRef" /&gt;
+			&lt;xs:element name="bundle" type="prov:IDRef" /&gt;
+		&lt;/xs:sequence&gt;
+	&lt;/xs:complexType&gt;
+	
+	&lt;xs:element name="mentionOf" type="prov:Mention" substitutionGroup="prov:internalElement" /&gt;
+	
+&lt;/xs:schema&gt;
+</pre>
+<p>All schemas developed by the PROV WG utilize the PROV namespace.</p>

+
+<section id="design-pattern">
+<h3><span class="secno">2.2 </span><i>Salami Slice</i> Design Pattern</h3>
+<p>The general design pattern for the XML schema has been called <i>Salami Slice Design</i> (cite?).  With this design, the individual components are each defined at the top level as separate elements with distinct types.  This allows the types to be easily reusable for domain specific extensions.</p>
+<p>The <code>prov:document</code> element has been defined to act as a convenient root element for a PROV-XML document, but it's use as the root element is not required.  The schema follows the Salami Slice pattern to ensure PROV XML elements can be integrated with mixed-schema XML documents which require a different document root.</p>
+</section> <!-- end design-pattern -->
+
+<section id="elements-vs-attributes">
+<h3><span class="secno">2.3 </span>Elements vs. Attributes</h3>
+
+<p>The general PROV-N syntax patterns for expressing provenance
+concepts are:
+</p>
+
+<pre class="codeexample">thing(id, elem1, elem2, ..., [attr1=val1, attr2=val2])
+concept(id; elem1, elem2, ... [attr1=val2, attr2=val2])
+</pre>
+
+<p>In both cases (required id or optional id), the PROV-N id is treated as an XML attribute (<code>prov:id</code>), the PROV-N "elements" are treated as XML elements, always with the same required order (position) as the PROV-DM/PROV-N description, and optional PROV-N "attributes", if allowed, always follow and are also represented by XML elements.  As in PROV-N, the attributes can be specified multiple times, but unlike PROV-N the attributes have a fixed (alphabetical) order.  The PROV-N "attribute" elements are always defined at the end of the encompassing sequence after all PROV-N "elements".  Elements defined in namespaces other than the PROV namespace may be included in a element after all PROV elements.</p>
+
+<p>Wherever an "id" is referenced from a later concept, the id is
+referenced as a prov:ref attribute of the element within the concept.
+</p>
+
+<p>This transformation technique yields a general XML pattern:
+</p>
+
+<pre class="codeexample">&lt;prov:thing prov:id="id"&gt;
+  &lt;prov:elem1 /&gt;
+  &lt;prov:elem2 /&gt;
+  ...
+  &lt;ex:attr1&gt;val1&lt;/ex:attr1&gt;
+  &lt;ex:attr2&gt;val2&lt;/ex:attr2&gt;
+  ...
+&lt;/prov:thing&gt;
+</pre>
+<p>Most of the concepts described below follow this general pattern.</p>
+</section> <!-- end elements-vs-attributes -->
+
+<section id="type-conventions">
+<h3><span class="secno">2.4 </span>Type Conventions</h3>
+<p>The PROV-DM states that type information is described using a the prov:type PROV attribute with and may occur multiple times for a given entity, activity, agent, or relation.</p>
+<p>PROV-XML uses the element <code>prov:type</code> to represent the prov:type PROV attribute.  This element can be use to represent both PROV and non-PROV type information.  The following examples shows type information encoded using the <code>prov:type</code> element.</p>
+<div class="example"><div class="example-title"><span>Example 1</span>: type information using prov:type PROV attribute</div><pre class="example" ignore="">&lt;prov:document
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xmlns:prov="http://www.w3.org/ns/prov#"
+    xmlns:ex="http://example.com/ns/ex#"
+    xmlns:tr="http://example.com/ns/tr#"&gt;
+
+  &lt;prov:entity prov:id="tr:WD-prov-dm-20111215"&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;prov:Plan&lt;/prov:type&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;ex:Workflow&lt;/prov:type&gt;
+  &lt;/prov:entity&gt;
+
+&lt;/prov:document&gt;</pre></div>
+<p>PROV-XML defines complexTypes to match the PROV defined type values.  These types provide a more native XML representation of PROV types.  The following example is considered equivalent to the previous example because the element <code>prov:plan</code> has type <code>prov:Plan</code>.</p>
+<div class="example"><div class="example-title"><span>Example 2</span>: type information using schema defined types</div><pre class="example" ignore="">&lt;prov:document
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xmlns:prov="http://www.w3.org/ns/prov#"
+    xmlns:ex="http://example.com/ns/ex#"
+    xmlns:tr="http://example.com/ns/tr#"&gt;
+
+  &lt;prov:plan prov:id="tr:WD-prov-dm-20111215"&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;ex:Workflow&lt;/prov:type&gt;
+  &lt;/prov:plan&gt;
+
+&lt;/prov:document&gt;</pre></div>
+<p>Because the <code>prov:Plan</code> complexType is defined as an extension of the complexType <code>prov:Entity</code>, the following example using <code>xsi:type</code> is valid and considered equivalent to the two previous examples. The attribute <code>xsi:type</code> tells an XML parser the complexType of the element.  The value of <code>xsi:type</code> must be a complexType derived from the default element type.</p>
+<div class="example"><div class="example-title"><span>Example 3</span>: type information using xsi:type</div><pre class="example" ignore="">&lt;prov:document
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xmlns:prov="http://www.w3.org/ns/prov#"
+    xmlns:ex="http://example.com/ns/ex#"
+    xmlns:tr="http://example.com/ns/tr#"&gt;
+
+  &lt;prov:entity prov:id="tr:WD-prov-dm-20111215" xsi:type="prov:Plan"&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;ex:Workflow&lt;/prov:type&gt;
+  &lt;/prov:entity&gt;
+
+&lt;/prov:document&gt;</pre></div>
+
+<p>The <code>prov:type</code> element is the only mechanism to explicitly declare multiple types for an instance or declare types that are not derived from the default element type. The <code>prov:type</code> element can be used in conjunction with schema-defined PROV types (see examples 2 and 3).</p>

+<p>The sixth component of PROV-DM is concerned with the notion of collections. 
+A collection is an entity that has some members. The members are themselves entities, and therefore their provenance can be expressed. Some applications need to be able to express the provenance of the collection  itself: e.g. who maintains the collection (attribution), which members it contains as it evolves, and how it was assembled. The purpose of Component 6 is to define the types and relations that are useful to express the provenance of collections.  </p>

+	<dd>PROV-XML is an XML language for describing the provenance of things; applications may evaluate given data to dereference URIs, invoking the security considerations of the scheme for that URI. Note in particular, the privacy issues in [<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10 for HTTP URIs. Data obtained from an inaccurate or malicious data source may lead to inaccurate or misleading conclusions, as well as the dereferencing of unintended URIs. Care must be taken to align the trust in consulted resources with the sensitivity of the intended use of the data.</dd>
+	<dd>PROV-XML can express data which is presented to the user, for example, by means of label attributes. Application rendering strings retrieved from untrusted PROV-N documents must ensure that malignant strings may not be used to mislead the reader. The security considerations in the media type registration for XML ([<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10) provide additional guidance around the expression of arbitrary data and markup.</dd>
+	<dd>PROV-XML is a language for describing the provenance of things, and therefore a PROV-XML document is metadata for other resources.  Untrusted PROV-XML documents may mislead its consumers by indicating that a third-party resource has a reputable lineage, when it has not. Provenance of PROV-XML document should be sought. </dd>
+	<dd>PROV-XML uses QNames mappable to IRIs as term identifiers. Applications interpreting data expressed in PROV-XML should address the security issues of

+  	<dd>Multiple IRIs may have the same appearance. Characters in different scripts may look similar (a Cyrillic "о" may appear similar to a Latin "o"). A character followed by combining characters may have the same visual representation as another character (LATIN SMALL LETTER E followed by COMBINING ACUTE ACCENT has the same visual representation as LATIN SMALL LETTER E WITH ACUTE).  Any person or application that is writing or interpreting data in PROV-N must take care to use the IRI that matches the intended semantics, and avoid IRIs that make look similar. Further information about matching of similar characters can be found in <a class="inform" href="http://www.unicode.org/reports/tr36/">Unicode Security Considerations</a> [<cite><a class="bibref" href="#bib-UNISEC">UNISEC</a></cite>] and <a class="norm" href="http://www.ietf.org/rfc/rfc3987.txt">Internationalized Resource Identifiers (IRIs)</a> [<cite><a class="bibref" href="#bib-RFC3987">RFC3987</a></cite>] Section 8.</dd>

Workgroup Notes provide extension schemas to define their Note-introduced PROV elements.

+<p>
+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. PROV-DM is the conceptual data model that forms a basis for the <abbr title="World Wide Web Consortium">W3C</abbr> provenance (PROV) family of specifications. It defines a concepts for expressing provenance information enabling interchange. This document introduces an XML schema for the PROV data model (PROV-DM), allowing instances of the PROV data model to be serialized in XML.

+For the purpose of this specification, <dfn id="dfn-provenance" class="internalDFN">provenance</dfn><sup><a class="internalDFN" href="#dfn-provenance"><span class="diamond"><span class="insert"> ◊</span></span></a></sup> is defined as a record that describes the people, institutions, entities, and activities involved in producing, influencing, or delivering a piece of data or a thing.  In particular, the provenance of information is crucial in deciding whether information is to be trusted, how it should be integrated with other diverse information sources, and how to give credit to its originators when reusing it.  In an open and inclusive environment such as the Web, where users find information that is often contradictory or questionable, provenance can help those users to make trust judgements.
+</p>
+
+<p>
+The PROV data model, PROV-DM, presents a generic data model for provenance that allows domain and application specific representations of provenance to be translated into such a data model and <em>interchanged</em> between systems.  Thus, heterogeneous systems can export their native provenance into such a core data model, and applications that need to make sense of provenance can then import it,
+process it, and reason over it.</p>
+
+<p>
+The PROV data model distinguishes <em>core structures</em> from <em>extended structures</em>: core structures form the essence of provenance information, and are commonly found in various domain-specific vocabularies that deal with provenance or similar kinds of information [<cite><a class="bibref" href="#bib-Mappings">Mappings</a></cite>].  Extended structures enhance and refine core structures with more expressive capabilities to cater for more advanced uses of provenance.  The PROV data model, comprising both core and extended structures, is a domain-agnostic model, but with clear extensibility points allowing further domain-specific and application-specific extensions to be defined.
+</p>
+
+<p>
+The PROV data model has a modular design and is structured according to six components covering various facets of provenance:</p>
+<ul>
+<li> component 1: entities and activities, and the time at which they were created, used, or ended;
+</li><li> component 2: derivations of entities from others;
+</li><li> component 3: agents bearing responsibility for entities that were generated and activities that happened;
+</li><li> component 4: bundles, a mechanism to support provenance of provenance;
+</li><li> component 5: properties to link entities that refer to a same thing;
+</li><li> component 6: collections forming a logical structure for its members.
+</li></ul>
+
+<p>
+This specification goal is to provide a succinct definition of the XML form of PROV-DM, thus, we refer the reader to the PROV-DM to provide overall justification and context to the definitions presented here.

+<p><span class="insert">The PROV-XML schema have been modularized so that extension elements defined in Working Group Notes can be defined in separate schemas.  Elements corresponding to terms defined in the PROV-DM are defined in the </span><b><span class="insert">prov-core.xsd</span></b><span class="insert"> schema and elements corresponding to terms defined in notes are defined in extension schemas (e.g. </span><b><span class="insert">prov-dictionary.xsd</span></b><span class="insert">, </span><b><span class="insert">prov-links.xsd</span></b><span class="insert">).  The default schema, </span><b><span class="insert">prov.xsd</span></b><span class="insert">, imports </span><b><span class="insert">prov-core.xsd</span></b><span class="insert"> and all extension schemas developed by the Working Group.  With this modeling all PROV elements, even those defined in Notes, are defined from the default schema.  If the user wishes to leverage a schema that does not include extension elements the user can use schemaLocation to directly reference </span><b><span class="insert">prov-core.xsd</span></b><span class="insert">.</span></p>

+<h3><span class="secno"><span class="insert">2.2 </span></span><i>Salami Slice</i> Design Pattern</h3>
+
+
+<p>The general design pattern for the XML schema has been
+ called <i>Salami Slice Design</i> (cite?).  With this design, the
+ individual components are each defined at the top level as separate
+ elements with distinct types.  This allows the types to be easily
+ reusable for domain specific extensions.
+</p>
+
+
+<p><span class="insert">The </span><code><span class="insert">prov:document</span></code><span class="insert"> element has been defined to act as a convenient root element for a PROV-XML document, but it's use as the root element is not required.  The schema follows the Salami Slice pattern to ensure PROV XML elements can be integrated with mixed-schema XML documents which require a different document root.</span></p>
+</section> 
+
+<section id="elements-vs-attributes">
+<h3><span class="secno"><span class="insert">2.3 </span></span>Elements vs. Attributes</h3>
+
+<p>The general PROV-N syntax patterns for expressing provenance
+concepts are:
+</p>
+
+<pre class="codeexample">thing(id, elem1, elem2, ..., [attr1=val1, attr2=val2])
+concept(id; elem1, elem2, ... [attr1=val2, attr2=val2])
+</pre>
+
+<p>In both cases (required id or optional id), the PROV-N id is
+ treated as an XML <span class="delete">attribute,</span><span class="insert">attribute (</span><code><span class="insert">prov:id</span></code><span class="insert">),</span> the PROV-N <span class="delete">&quot;elements&quot;</span><span class="insert">"elements"</span> are treated as XML
+ elements, always with the same required order (position) as the
+ PROV-DM/PROV-N description, and optional PROV-N <span class="delete">&quot;attributes&quot;,</span><span class="insert">"attributes",</span> if
+ allowed, always follow and are also represented by XML elements.  As
+ in PROV-N, the attributes can be specified multiple times, <span class="delete">and</span><span class="insert">but unlike PROV-N the attributes have a fixed (alphabetical) order.  The PROV-N "attribute" elements are always defined at the end of the encompassing sequence after all PROV-N "elements".  Elements defined</span> in <span class="delete">any
+order, as long as they are</span><span class="insert">namespaces other than the PROV namespace may be included in a element after</span> all <span class="delete">at the end of the encompassing element.
+</span><span class="insert">PROV elements.</span></p>
+
+<p>Wherever an <span class="delete">&quot;id&quot;</span><span class="insert">"id"</span> is referenced from a later concept, the id is
+referenced as a prov:ref attribute of the element within the concept.
+</p>
+
+<p>This transformation technique yields a general XML pattern:
+</p>
+
+<pre class="codeexample">&lt;prov:thing <span class="delete">prov:id=&quot;id&quot;&gt;</span><span class="insert">prov:id="id"&gt;</span>
+  &lt;prov:elem1 /&gt;
+  &lt;prov:elem2 /&gt;
+  ...
+  <span class="delete">&lt;prov:attr1&gt;val1&lt;/prov:attr1&gt;
+  &lt;prov:attr2&gt;val2&lt;/prov:attr2&gt;</span><span class="insert">&lt;ex:attr1&gt;val1&lt;/ex:attr1&gt;
+  &lt;ex:attr2&gt;val2&lt;/ex:attr2&gt;</span>
+  ...
+&lt;/prov:thing&gt;
+</pre>
+
+
+<p>Most of the concepts described below follow this general pattern.

+<h3><span class="secno">3.6 </span>Component 6: Collections</h3>
+<p>The sixth component of PROV-DM is concerned with the notion of collections. 
+A collection is an entity that has some members. The members are themselves entities, and therefore their provenance can be expressed. Some applications need to be able to express the provenance of the collection  itself: e.g. who maintains the collection (attribution), which members it contains as it evolves, and how it was assembled. The purpose of Component 6 is to define the types and relations that are useful to express the provenance of collections.  </p>
