Hi all,

As trailed earlier, I've been playing with SPARQL queries on the sort of 
data we're starting to build. In particular, I want to see how the 
resource grouping issue tumbles out and whether the queries become so 
ridiculous as to warrant a serious consideration of an alternative 
approach.

To this end I've created a file full of DRs with different (and 
increasingly complex) Resource Sets and worked through some test 
queries. It's not finished yet but I've been at it all day and we're 
heading into a holiday weekend so it'll have to do for now. I believe, 
however, that with a small number of queries it's possible to extract 
all the necessary data from a DR, including all the attribution, scope 
and description data. Obviously it gets more difficult if you have 
complex data but essentially, it's looking quite simple - I think.

CÚdric - can I ask you to upload this to the (public) web space please. 
Meanwhile, it's attached.

Cheers

Phil.
