<h1>Exiv2 Tag Tables</h1>
<h2>XMP Media Management Schema</h2>
<p>The XMP Media Management Schema is primarily for use by digital asset management (DAM) systems.</p>
<p>The following XMP properties are "owned" by the DAM system and should be set by applications
under their direction; they should not be used by unmanaged files: xmpMM:ManagedFrom,
xmpMM:Manager, xmpMM:ManageTo, xmpMM:ManageUI, xmpMM:ManagerVariant.</p>
<p>The following properties are owned by the DAM system for managed files, but can also be
used by applications for unmanaged files: xmpMM:DerivedFrom, xmpMM:DocumentID,
xmpMM:RenditionClass, xmpMM:RenditionParams, xmpMM:VersionID, xmpMM:Versions.</p>
<p>The xmpMM:History property is always owned by the application.
<ul>
<li>Exiv2 keys are <b><code>Xmp.xmpMM.<Property></code></b>
<li>The schema namespace URI is <b><code>http://ns.adobe.com/xap/1.0/mm/</code></b></li>
<li>The preferred schema namespace prefix is <b><code>xmpMM</code></b></li>
</ul>

<tr class="OddRow">
<td>DerivedFrom</td>
<td>Derived From</td>
<td>ResourceRef</td>
<td>XmpText</td>
<td>Internal</td>
<td>A reference to the original document from which this one is derived. It is a minimal reference; missing components can be assumed to be unchanged. For example, a new version might only need to specify the instance ID and version number of the previous version, or a rendition might only need to specify the instance ID and rendition class of the original.</td>

<tr class="EvenRow">
<td>DocumentID</td>
<td>Document ID</td>
<td>URI</td>
<td>XmpText</td>

<td>The common identifier for all versions and renditions of a document. It should be based on a UUID; see Document and Instance IDs below.</td>

<td>History</td>
<td>seq ResourceEvent</td>
<td>XmpText</td>
<td>Internal</td>
<td>An ordered array of high-level user actions that resulted in this resource. It is intended to give human readers a general indication of the steps taken to make the changes from the previous version to this one. The list should be at an abstract level; it is not intended to be an exhaustive keystroke or other detailed history.</td>

<tr class="EvenRow">
<td>InstanceID</td>
<td>Instance ID</td>
<td>URI</td>
<td>XmpText</td>

<td>An identifier for a specific incarnation of a document, updated each time a file is saved. It should be based on a UUID; see Document and Instance IDs below.</td>
</tr>
<tr class="OddRow">
<td>ManagedFrom</td>
<td>Managed From</td>
<td>ResourceRef</td>
<td>XmpText</td>
<td>Internal</td>
<td>A reference to the document as it was prior to becoming managed. It is set when a managed document is introduced to an asset management system that does not currently own it. It may or may not include references to different management systems.</td>
</tr>
<tr class="EvenRow">
<td>Manager</td>
<td>Manager</td>
<td>AgentName</td>
<td>XmpText</td>
<td>Internal</td>
<td>The name of the asset management system that manages this resource. Along with xmpMM: ManagerVariant, it tells applications which asset management system to contact concerning this document.</td>
</tr>
<tr class="OddRow">
<td>ManageTo</td>
<td>Manage To</td>
<td>URI</td>
<td>XmpText</td>
<td>Internal</td>
<td>A URI identifying the managed resource to the asset management system; the presence of this property is the formal indication that this resource is managed. The form and content of this URI is private to the asset management system.</td>
</tr>
<tr class="EvenRow">
<td>ManageUI</td>
<td>Manage UI</td>
<td>URI</td>
<td>XmpText</td>
<td>Internal</td>
<td>A URI that can be used to access information about the managed resource through a web browser. It might require a custom browser plug-in.</td>
</tr>
<tr class="OddRow">
<td>ManagerVariant</td>
<td>Manager Variant</td>
<td>Text</td>
<td>XmpText</td>
<td>Internal</td>
<td>Specifies a particular variant of the asset management system. The format of this property is private to the specific asset management system.</td>
</tr>
<tr class="EvenRow">
<td>RenditionClass</td>
<td>Rendition Class</td>
<td>RenditionClass</td>
<td>XmpText</td>
<td>Internal</td>
<td>The rendition class name for this resource. This property should be absent or set to default for a document version that is not a derived rendition.</td>
</tr>
<tr class="OddRow">
<td>RenditionParams</td>
<td>Rendition Params</td>
<td>Text</td>
<td>XmpText</td>
<td>Internal</td>
<td>Can be used to provide additional rendition parameters that are too complex or verbose to encode in xmpMM: RenditionClass.</td>
</tr>
<tr class="EvenRow">
<td>VersionID</td>
<td>Version ID</td>
<td>Text</td>
<td>XmpText</td>
<td>Internal</td>
<td>The document version identifier for this resource. Each version of a document gets a new identifier, usually simply by incrementing integers 1, 2, 3 . . . and so on. Media management systems can have other conventions or support branching which requires a more complex scheme.</td>
</tr>
<tr class="OddRow">
<td>Versions</td>
<td>Versions</td>
<td>seq Version</td>
<td>XmpText</td>
<td>Internal</td>
<td>The version history associated with this resource. Entry [1] is the oldest known version for this document, entry [last()] is the most recent version. Typically, a media management system would fill in the version information in the metadata on check-in. It is not guaranteed that a complete history versions from the first to this one will be present in the xmpMM:Versions property. Interior version information can be compressed or eliminated and the version history can be truncated at some point.</td>
