DC:Type selected from enumerated list

Warning: the RDF syntax currently shown here is OUT OF DATE!

This example provides a description of the UKOLN home page. It takes the value for DC.Type from the enumerated list offered at http://sunsite.berkeley.edu/Metadata/structuralist.html. It provides an example of the use of a namespace for a 'SCHEME' that is not yet well established. (Here we use the name DCRT, short for Dublin Core Resource Types).
