Bases: ShapeParser

parseShapesFromDir(path, shapeFormat, useSelectiveQueries, maxSplitSize, ORDERBYinQueries)[source]#

Parses shapes from a directory. However, shapes are only relevant if they occur in the query or are reachable from shapes occurring in the query. The remaining shapes can be removed.

replace_target_query(shape, query)[source]#
shape_get_id(shape)[source]#
parseConstraints(shapeName, array, targetDef, constraintsId)[source]#
parse_constraints_ttl(array, target_def, constraints_id)[source]#
parseConstraint(varGenerator, obj, id, targetDef)[source]#
Constraints are only relevant if:

  • subject and object do both NOT belong to the targetShape OR

  • subject or object belong to the targetShape AND the predicate is part of the query (-> inverted paths can be treated equally to normal paths)

Other constraints are not relevant and result in an empty list.

shapeReferences(constraints)[source]#

Constraints and references are parsed independently based on the input SHACL shape schema. Constraints that are removed in parse_constraint() should not appear in the references. self.removed_constraints keeps track of the removed constraints

shape_references is used to get the references in self.currentShape to other shapes. It then returns ONE path of a constraint referencing to that shape (The other ones are ignored?!)

computeReducedEdges(shapes)[source]#

Computes the edges in the network.

Returns unidirectional dependencies of the shapes in the network.
