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.
