<h1 id="overview">Overview</h1>
<h2 id="introduction">Introduction</h2>
<p>This ontology extends NIE (Nepomuk Information Element ontology) and NFO (Nepomuk File Ontology) into the domains of multimedia, including Images, Videos, Music and Radio, and includes a couple of properties to support uPnP sharing.</p>
<p>This ontology replaces/complements NID3 and NEXIF. Those ontologies are a direct map of the respective metadata standards, which makes very difficult to map cleanly other standards (like gstreamer metadata, mp4, ogg, and so on). Besides, those ontologies contain a lot of very low level technical information that is useless to the average user of the desktop.</p>
<p>Our approach in NMM is to keep the minimum properties that make sense for the user, and are present in all (or almost all) specific metadata formats. A profesional photographer (or musician) who needs more fine-grained details for its documents, is free to add also nID3 information or other extensions to the ontology.</p>
<h2 id="images-domain">Images domain</h2>
<p>The core of images in NMM ontology is the class <a href="nmm-ontology.html#nmm:Photo">nmm:Photo</a>. It is (through a long hierarchy) a <a href="nie-ontology.html#nie:InformationElement">nie:InformationElement</a>, an interpretation of some bytes. It has properties to store the basic information (camera, metering mode, white balance, flash), and inherits from <a href="nfo-ontology.html#nfo:Image">nfo:Image</a> orientation (<a href="nfo-ontology.html#nfo:orientation">nfo:orientation</a>) and resolution (<a href="nfo-ontology.html#nfo:verticalResolution">nfo:verticalResolution</a> and <a href="nfo-ontology.html#nfo:horizontalResolution">nfo:horizontalResolution</a>).</p>
<p>Note that for tags, nie:keywords (from nie:InformationElement) can be used, or the <a href="nao-ontology.html">NAO</a> ontology.</p>
<h2 id="radio-domain">Radio domain</h2>
<p>NMM includes classes and properties to represent analog and digital radio stations. There is a class <a href="nmm-ontology.html#nmm:RadioStation">nmm:RadioStation</a> on the <a href="nie-ontology.html#nie:InformationElement">nie:InformationElement</a> side of the ontology, representing what the user sees about that station (genre via PTY codes, icon, plus title inherited from nie:InformationElement)</p>
<p>A <a href="nmm-ontology.html#nmm:RadioStation">nmm:RadioStation</a> can have one or more <a href="nmm-ontology.html#nmm:carrier">nmm:carrier</a> properties representing the different frequencies (or links when it is digitial) it can be tuned. This property links the station with <a href="nfo-ontology.html#nfo:MediaStream">nfo:MediaStream</a>, but usually it will point to one of the subclasses: <a href="nmm-ontology.html#nmm:DigitalRadio">nmm:DigitalRadio</a> (if digital) or <a href="nmm-ontology.html#nmm:AnalogRadio">nmm:AnalogRadio</a> (if analog). An analog station has properties as modulation and frequency, while the digial station has streaming bitrate, encoding or protocol.</p>
<p>Note that nfo:MediaStream refers to a flux of bytes/data, and it is on the <a href="nie-ontology.html#nie:DataObject">nie:DataObject</a><link linkend="nie-DataObject">nie:DataObject side of the ontology.</p>
