<sect2 id="nie-introduction">
<title>Introduction</title>
<para>The core of the NEPOMUK Information Element Ontology and the entire
  Ontology Framework revolves around the concepts of <link linkend="nie-DataObject">DataObject</link> and
 <link linkend="nie-InformationElement">InformationElement</link>. They express  the representation
 and content of a piece of data. Their specialized subclasses (defined
 in the other ontologies) can be used to classify
 a wide array of desktop resources and express them in RDF.
</para>

<para>
 <link linkend="nie-DataObject">nie:DataObject</link> class represents a bunch of
 bytes somwhere (local or remote), the physical entity that contain
 data. The <emphasis>meaning</emphasis> (intepretation) of that entity, the
 information for the user contained in those bytes (e.g. a music file,
 a picture) is represented on the
<link linkend="nie-InformationElement">nie:InformationElement</link> side of the
ontology.
</para>

<para>
Both sides are linked using the
property <link linkend="nie-interpretedAs">nie:interpretedAs</link> (and its reverse
<link linkend="nie-isStoredAs">nie:isStoredAs</link>), indicating the correspondence
between the physical element and its interpretation. There is also a
property to
link <link linkend="nie-InformationElement">nie:InformationElement</link>s,
representing the logical containment between them (like a picture and
its album).
</para>

  <title>Common properties</title>
  <para>
    Given that the classes defined in this ontology are the superclasses for almost
    everything in the Nepomuk set of ontologies, the
    properties defined here will be inherited for a lot of classes. It is
    worth to comment few of them with special relevance:

<title>Dates and timestamps representations</title>
<para>There are few important dates for the life-cycle of a resource. These dates are properties of the nie:InformationElement class, and inherited for its subclasses:</para>

    <listitem>
      <para>Creation time of the content. If the contents is created by an application, the same application should set the value of this property. Note that this property can be undefined for resources in the filesystem because the creation time is not available in the most common filesystem formats.</para>

<refsect2 id="nie-uri-representation">
<title>URIs and full representation of a file</title>
<para>One of the most common resources in a desktop is a file. Given the split between Data Objects and Information Elements, some times it is not clear how a real file is represented into Nepomuk. Here are some indications:</para>
<orderedlist>
 <listitem>Every file (local or remote) should generate one DataObject instance and an InformationElement instance.</listitem>
 <listitem>Even when Data Objects and Information Elements are completely different things, for efficency reasons in Tracker we use the same URI for both of them.</listitem>
 <listitem>The URI will be an autogenerated ID, and the real location of the item (e.g. ''file://path/to/file.mp3'') is a property of the Data Object</listitem>
 <listitem>Every DataObject must have the property <link linkend="nie-url">nie:url</link>, that points to the location of the resource, and should be used by any program that wants to access it.</listitem>
 <listitem>There is a deprecated property in the ontology: <link linkend="nie-isStoredAs">nie:isStoredAs</link> . We discourage its use in the code: in the best case it is a loopback to the nie:url value, but in general it can contain any value or not be set at all.</listitem>
</orderedlist>

<para>Here comes an example, for the image file /home/user/a.jpeg:</para>

<programlisting>
&lt;urn:uuid:10293801928301293&gt; a nmm:Photo, nfo:FileDataObject ;

<title>nie:DataSource</title>
<para>A superclass for all entities from which DataObjects can be extracted. Each entity represents a native application or some other system that manages information that may be of interest to the user of the Semantic Desktop. Subclasses may include FileSystems, Mailboxes, Calendars, websites etc. The exact choice of subclasses and their properties is considered application-specific. Each data extraction application is supposed to provide it's own DataSource ontology. Such an ontology should contain supported data source types coupled with properties necessary for the application to gain access to the data sources. (paths, urls, passwords etc...)</para>

<title>nie:DataObject</title>
<para>A unit of data that is created, annotated and processed on the user desktop. It represents a native structure the user works with. The usage of the term 'native'	is important. It means that a DataObject can be directly mapped to a data structure maintained by a native application.	This may be a file, a set of files or a part of a file. The granularity depends on the user. This class is not intended to be instantiated by itself. Use more specific subclasses.</para>
