The type or genre of a dataset <em title="MAY" class="rfc2119">MAY</em> be indicated using the <a href="http://purl.org/dc/terms/type">dct:type</a> property.
The value of the property <em title="SHOULD" class="rfc2119">SHOULD</em> be taken from a well governed and broadly recognised set of resource types, such as the <a href="http://dublincore.org/documents/dcmi-terms/#section-7">DCMI Type Vocabulary</a>, the <a href="https://id.loc.gov/vocabulary/marcgt.html">MARC Genre/Terms Scheme</a>, the <a href="https://schema.datacite.org/meta/kernel-4.1/include/datacite-resourceType-v4.1.xsd">DataCite resource types</a> or the PARSE.Insight content-types from Re3data [[re3data-schema]].
