Functions

diffset_to_templates(grouped_diffset)

Combine GraphDiff by focus node to generate a list of templates that reconcile what is "wrong" with the Graph with respect to the GraphDiffs.

Classes

GraphClassCardinality(focus, ...)

Represents a graph that is missing an expected number of instances of the given class.

GraphDiff(focus, validation_result, graph)

An abstraction of a SHACL Validation Result that can produce a template that resolves the difference between the expected and actual graph.

PathClassCount(focus, validation_result, ...)

Represents an entity missing paths to objects of a given type: $this <path> <object> .

PathShapeCount(focus, validation_result, ...)

Represents an entity missing paths to objects that match a given shape.

RequiredClass(focus, validation_result, ...)

Represents an entity that should be an instance of the class.

RequiredPath(focus, validation_result, ...)

Represents an entity missing a required property.

ValidationContext(shape_collections, ...)

Holds the necessary information for processing the results of SHACL validation.

class GraphDiff(focus: Optional[URIRef], validation_result: Graph, graph: Graph)[source]#

An abstraction of a SHACL Validation Result that can produce a template that resolves the difference between the expected and actual graph.

Each GraphDiff has a ‘focus’ that is the node in the model that the GraphDiff is about. If ‘focus’ is None, then the GraphDiff is about the model itself rather than a specific node
