In the Southampton buildings data;
<a class="moz-txt-link-freetext" href="http://data.southampton.ac.uk/dataset/places.html">http://data.southampton.ac.uk/dataset/places.html</a> we use the WKT
markup <a class="moz-txt-link-rfc2396E" href="http://en.wikipedia.org/wiki/Well-known_text"><http://en.wikipedia.org/wiki/Well-known_text></a> in a
dcterms:spatial literal to describe polygons. It's got more
semantics than that, because it's WKT where the values are latitude
and longitude.<br>
<br>
I've been thinking of defining a data type for this to make it less
hacky. eg.<br>
<br>
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
<pre><a class="moz-txt-link-rfc2396E" href="http://id.southampton.ac.uk/building/1"><http://id.southampton.ac.uk/building/1></a>
<a class="moz-txt-link-rfc2396E" href="http://purl.org/dc/terms/spatial"><http://purl.org/dc/terms/spatial></a> "POLYGON((-1.3962631 50.9375993,-1.3960836 50.9378388,-1.3958288 50.9377629,-1.3960083 50.9375235,-1.3962631 50.9375993))"<u><b>^^<a class="moz-txt-link-rfc2396E" href="http://purl.org/openorg/WKTLatLongType"><http://purl.org/openorg/WKTLatLongType></a></b></u> .
</pre>
It will give it explicit semantics without making it more difficult
to consume.<br>
