+<p>Several distinct temporal descriptors are shown for this dataset. The dataset publication and revision dates are shown in <a href="#Property:resource_release_date"><code>dct:issued</code></a> and <a href="#Property:resource_update_date"><code>dct:modified</code></a>. For the frequency of update of the dataset in <a href="#Property:dataset_frequency"><code>dct:accrualPeriodicity</code></a>, we use an instance from the <a href="http://www.w3.org/TR/vocab-data-cube/#dsd-cog">Content-Oriented Guidelines</a> developed as part
+    of the <abbr title="World Wide Web Consortium">W3C</abbr> Data Cube Vocabulary [[?VOCAB-DATA-CUBE]] efforts. The temporal coverage or extent is given in <a href="#Property:dataset_temporal"><code>dct:temporal</code></a> using an item from the Interval dataset (originally available from http://reference.data.gov.uk/id/interval) from data.gov.uk. </p>
+    <p>Additionally, the spatial coverage or extent is given <a href="#Property:dataset_spatial"><code>dct:spatial</code></a> using a URI from <a href="http://www.geonames.org/">Geonames</a>. The spatial resolution, which describes the minimum spatial separation of items within the dataset, is given in <a href="#Property:dataset_spatialresolution"><code>dcat:spatialResolutionInMetres</code></a> using the standard datatype <code>xsd:decimal</code>. A contact point is provided where comments and feedback about the dataset can be sent.
