ISSUE-74: Should SHACL support validating RDF graphs accessible via unmodified SPARQL endpoints

SPARQL endpoint support

Should SHACL support validating RDF graphs accessible via unmodified SPARQL endpoints

State:
CLOSED
Product:
SHACL Spec
Raised by:
Peter Patel-Schneider
Opened on:
2015-07-12
Description:
Should it be possible to validate SHACL shapes on RDF graphs that are only accessible via unmodified SPARQL endpoints?

For example, suppose
G = { < ex:a ex:r _:a .
_:a ex:q ex:b . }
is a data graph to be validated against the shapes
S1 = ex:r S2 [1,1]
S2 = ex:q [1,1]

Should it be possible to perform the validation if the only access G is via SPARQL queries?

Related notes:

Resolution: Close ISSUE-74, answer is no but we'll add some informative text to the spec talking about the pitfalls of validating against a SPARQL endpoint and we should keep in mind that some people will want to validate against an endpoint so we don't make it arbitrarily difficult.
