Hi Alasdair

Some results from http://lov.okfn.org/dataset/lov/search/#s=dataset

http://purl.org/dc/dcmitype/Dataset is quite generic, but does not have any
attached properties.
http://purl.org/ctic/dcat#Dataset is a subclass of the above, is intended
to represent datasets in a catalogue, and is not limited to RDF datasets

... many more I let you explore

Hope that helps

Bernard
