I agree with all that - it is a description of what I have been saying.
We clearly have a strong agreement here.

On the other hand:
Thus SPARQL is not a required part of the Linked Data meme. Also if Named
Graphs are not visible without using SPARQL, Named Graphs are not a good
solution to problems in the Linked Data meme.

This will become a more significant issue with the forthcoming explosion of
Linked Data from governments such as the UK, where the data provider will
not be offering a SPARQL endpoint.

Telling them to put their co-ref data in a Named Graph is just not an
option.

Best
Hugh
