<p class="note">From DCAT 1.0</p>

<p>Data can come in many formats, ranging from spreadsheets, through XML and RDF, to various speciality formats. DCAT does not make any assumptions about the serialisation 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 [[void]] 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>
