Hi Richard,
  The use case is being driven to a large extent by our work to provide 
summary statistics for Bio2RDF datasets. You can see an example of a 
dataset page here:

http://download.bio2rdf.org/release/2/drugbank/drugbank.html

and a view of all the datasets here
http://download.bio2rdf.org/release/2/release.html

we want to provide specific recommendations on the structure of a dataset 
description, so that they are available for download, and query in an 
endpoint.  that way people won't be querying our endpoint over and over 
with the same statistics gathering queries.
