If as a speaker I tailor my words to exactly match the shapes that every 
audience member wants, I can only talk to very small audiences (less than or 
equal to 1, probably).  This is, of course, a speaker model, but often not a 
very good one.  If as a company I tailor my products to exactly match the 
shapes that every customer wants, I end up creating very many products 
(probably more variations of each product than I have customers of that 
product).  This is, of course, a business model that can be effective in some 

As a publisher of RDF should I follow this route?  I say no!  More, I say that 
this is against the principles of the Web.

This is not to say that there can't be situations where RDF is used in 
one-to-one settings, and it may be expedient for the producer to tailor its 
output to match the desires of the consumer.  However, these situations are 
likely to involve constraints on more than the shape of the RDF, for example 
requirements concerning precisely what is and what is not produced at a 
content level.

It seems to me that remote SPARQL execution is a better model for this sort of 
one-to-one interaction, and that this model is not against the principles of 
the Web as there is a publishable RDF graph that the queries are performed
