[Buildingdata] data type for lat/long Well Known Text

[Christopher Gutteridge]

In the Southampton buildings data; 
http://data.southampton.ac.uk/dataset/places.html we use the WKT markup 
<http://en.wikipedia.org/wiki/Well-known_text> 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.

I've been thinking of defining a data type for this to make it less 
hacky. eg.

<http://id.southampton.ac.uk/building/1>
     <http://purl.org/dc/terms/spatial>  "POLYGON((-1.3962631 50.9375993,-1.3960836 50.9378388,-1.3958288 50.9377629,-1.3960083 50.9375235,-1.3962631 50.9375993))"_*^^<http://purl.org/openorg/WKTLatLongType>*_  .

It will give it explicit semantics without making it more difficult to 
consume.
