Swish.RDF.ClassRestrictionRule
Description
This module implements an inference rule based on a restruction on class membership of one or more values.

type ClassRestrictionFn = [Maybe RDFLabel] -> Maybe [[RDFLabel]] Source #
Type of function that evaluates missing node values in a restriction from those supplied.
makeDatatypeRestriction :: RDFDatatypeVal vt -> DatatypeRel vt -> ClassRestriction Source #
Make a class restriction from a datatype relation.
This lifts application of the datatype relation to operate
on RDFLabel values, which are presumed to contain appropriately
datatyped values.
makeDatatypeRestrictionFn :: RDFDatatypeVal vt -> DatatypeRelFn vt -> ClassRestrictionFn Source #
Make a class restriction function from a datatype relation function.
makeRDFClassRestrictionRules :: [ClassRestriction] -> RDFGraph -> [RDFRule] Source #
Make a list of class restriction rules given a list of class restriction values and a graph containing one or more class restriction definitions.
makeRDFDatatypeRestrictionRules :: RDFDatatypeVal vt -> RDFGraph -> [RDFRule] Source #
Make restriction rules from the supplied datatype and graph.
falseGraph :: RDFGraph Source #
The graph
_:a <http://id.ninebynine.org/2003/rdfext/rdfd#false> _:b .
Exported for testing.
falseGraphStr :: Builder Source #
Exported for testing.
