To answer the question about  "datasets about datasets", William
Waites  has done some excellent work to produce RDF from CKAN at
http://semantic.ckan.net/, which we are building on for the Dataset
Inventory for the LATC project: http://dsi.lod-cloud.net/  (work in
progress)   which has a SPARQL endpoint at
http://dsi.lod-cloud.net/sparql

The clever folks behind rkbexplorer have also created a repository of
VoID data at http://void.rkbexplorer.com/

With regards to dataset URIs - with some datasets, the dataset
publisher has chosen to use the base URI (eg:
http://data.ordnancesurvey.co.uk ) as the URI of the dataset. In other
cases the dataset publisher has chosen a different pattern. There
isn't a right or wrong - it's up to the publisher to decide what their
URIs mean. In some cases, for instance, it is more convenient for the
publisher to use a hash URI in a hand-curated file, and that's fine.

You are right though, that currently the patterns for discovering
dataset descriptions (such as .well-known/void or "<doc>
void:inDataset <dataset>" triples ) are not as widely implemented as
they could be.
