Re: Role of SPARQL

Is this something we can resolve without knowing which technology we are 
going to use though?

Subject:        Role of SPARQL



I think we should raise an issue to determine the role of SPARQL in this 
stack. One of the reasons why I believe this is an important direction 
is that it will impact ISSUE-1 (inferencing). For example, see the 
unresolved feature request brought to our attention by Axel:

http://www.w3.org/2009/sparql/wiki/Feature:ParameterizedInference

The interaction is that if SPARQL (in general) had a syntax to specify 
entailment regimes, and Shapes are based on SPARQL, then the topic of 
inferencing may become a non-issue from a Shapes perspective - it would 
be solved in the lower parts of the stack.

 From what I can guess by listening to previous discussions, many people 
here are in favor of defining Shapes with SPARQL semantics, at least 
with a mapping/compilation to SPARQL, so I believe this is a topic that 
we should formally discuss and resolve.
