+<h2>Abstract</h2>
+  <p>DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use.</p>
+  <p>By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.</p>

+<p>Data can come in many formats, ranging from spreadsheets over XML and RDF to various  <del style="background:#F00">speciality</del><ins style="background:#0F0">specialist</ins> formats. DCAT does not make any assumptions about the format of the datasets described in a catalog. Other, complementary vocabularies may be used together with DCAT to provide more detailed format-specific information. For example, properties from the VoID vocabulary [<cite><a class="bibref" href="#bib-VOID">VOID</a></cite>] can be used to express various statistics about a DCAT-described dataset if that dataset is in RDF format.</p>
+<p>This document does not prescribe any particular method of deploying data expressed in DCAT. DCAT is applicable in many contexts including RDF accessible via SPARQL endpoints, embedded in HTML pages as RDFa, or serialized as e.g. RDF/XML or Turtle. The examples in this document use Turtle simply because of Turtle's readability.</p>

+<p>DCAT is an RDF vocabulary well-suited to representing government data catalogs such as <a href="http://data.gov">data.gov</a> and <a href="http://data.gov.uk">data.gov.uk</a>. DCAT defines three main classes:</p>
+<ul><li> <code><a href="#Class:_Catalog">dcat:Catalog</a></code> represents the catalog
+</li><li> <code><a href="#Class:_Dataset">dcat:Dataset</a></code> represents a dataset in a  <del style="background:#F00">catalog</del><ins style="background:#0F0">catalog.</ins> 
+</li><li> <code><a href="#Class:_Distribution">dcat:Distribution</a></code> represents an accessible form of a dataset as for example a downloadable file, an RSS feed or a web service that provides the data.

+<p>Another important class in DCAT is <code><a href="#Class:_Catalog_record">dcat:CatalogRecord</a></code> which describes a dataset entry in the catalog. Notice that while dcat:Dataset represents the dataset itself, dcat:CatalogRecord represents the record that describes a dataset in the catalog. The use of the CatalogRecord is considered optional. It is used to capture provenance information about dataset entries in a catalog. If this distinction is not necessary then CatalogRecord can be safely ignored.</p>

+<p>This example provides a quick overview of how DCAT might be used to represent a government catalog and its datasets. </p>
+
+<p>First, the catalog description:
+</p>
+<pre>   :catalog
+       a dcat:Catalog ;
+       dct:title "Imaginary Catalog" ;
+       rdfs:label "Imaginary Catalog" ;

+       dcat:dataset :dataset-001  , :dataset-002 , :dataset-003 ; 
+       .
+</pre>
+<p>The publisher of the catalog has the relative URI :transparency-office. Further description of the publisher can be provided as in the following example:
+</p>
+<pre>   :transparency-office
+       a foaf:Organization ;
+       rdfs:label "Transparency Office" ;
+       .
+</pre>
+<p>The catalog lists each of its datasets via dcat:dataset property. In the example above, an example dataset was mentioned with the relative URI :dataset-001. A possible description of it using DCAT is shown below:
+</p>
+<pre>   :dataset-001
+       a dcat:Dataset ;

+<p>The dataset distribution :dataset-001-csv can be downloaded as a 5Kb CSV file. This information is
