I need SPIN because my SHACL sh:constraint sh:sparql SPARQL query
calls SPIN functions (some stock and some custom).
The SPIN functions can be registered with the SPARQL engine separately
and do not need to be in the same graph as the SHACL data. The two
worlds interact only via the ARQ SPARQL engine's functions registry.
I flattened as suggested into a single turtle file.
I had some test values in the schema so I piped the schema back in as
the test data and got some results (yay!).
Now the issue is that the results don't match what I am seeing in the
TBC SHACL Validation tab. In TBC the SHACL Validation tab shows:
Shape, Constraint, Message, Focus Node, Subject, Predicate, and
Object. The Shape data is similar to the result in the test case, but
none of the other SHACL property values are the same, most notably the
Message and Focus Node values. In TBC the Focus Node (which seems to
be the same as sh:subject) is bound to instances, and the Message
(sh:message) value is bound to the message I defined and bound to the
values my SPARQL query returns. And example of the results I am seeing
from the test case is:
[ a sh:ValidationResult ;
sh:focusNode eddl:BlockB ;
sh:message "Value does not have class
sh:PropertyConstraint" ;
sh:path sh:property ;
sh:severity sh:Violation ;
sh:sourceConstraint _:b0 ;
sh:sourceConstraintComponent sh:ClassConstraintComponent ;
sh:sourceShape sh:Shape ;
sh:value []
] .
So now I am thinking that maybe I am using the wrong validator. Is it
possible that I should be using the ResourceConstraintValidator
instead of the ModelConstraintValidator? And if so, it takes a
resource as the first argument unlike TBC which traverses the current
graph.
So are you saying the result instances are different, i.e. they report
different violations? Or is just the format (e.g. sh:focusNode vs.
sh:subject) different? The latter is easy to explain: the SHACL API is
ahead of the TBC release cycle, and only the API follows the very latest
syntax changes to SHACL.
