cmem-plugin-pyshacl 4.2.0rc2

Validate your Knowledge Graphs based on tests generated from SHACL shapes.

cmem-plugin-pyshacl

This is a plugin for eccenca Corporate Memory plugin performing SHACL validation with pySHACL.

Installation

cmemc admin workspace python install cmem-plugin-pyshacl

Options

Data graph URI

The URI of the graph to be validated. The graph URI is selected from a list of graphs of types:

• di:Dataset
• dsm:ThesaurusProject
• owl:Ontology
• shui:ShapeCatalog
• void:Dataset

SHACL graph URI

The URI of the graph containing the SHACL shapes to be validated against. The graph URI is selected from a list of graphs of type shui:ShapeCatalog.

Generate validation graph

If enabled, the validation graph is posted to the CMEM instance with the graph URI specified with the validation graph URI option. Default value: false.

Validation graph URI

If the generate validation graph option is enabled the validation graph is posted to the CMEM instance with this graph URI.

Output entities

If enabled, the plugin outputs the validation results and can be connected to, for instance, a CSV dataset to produce a results table. Default value: false.

Clear validation graph

If enabled, the validation graph is cleared before workflow execution. Default value: true.

Advanced Options

Resolve owl:imports

If enabled, the graph tree defined with owl:imports in the data graph is resolved. Default value: true.

Blank node skolemization

If enabled, blank nodes in the validation graph are skolemized into URIs. Default value: true.

Add labels

If enabled, rdfs:label triples are added to the validation graph for instances of sh:ValidationReport and sh:ValidationResult. Default value: true.

Add labels from data and SHACL graphs

If enabled along with the add labels option, rdfs:label triples are added for the focus nodes, values and SHACL shapes in the validation graph. The labels are taken from the specified data and SHACL graphs. Default value: false.

Add shui:conforms flag to focus node resources

If enabled, shui:conforms false triples are added to the focus nodes in the validation graph. Default value: false.

Meta-SHACL

If enabled, the SHACL shapes graph is validated against the SHACL-SHACL shapes graph before validating the data graph. Default value: false.

Ontology graph URI

The URI of a graph containing extra ontological information. RDFS and OWL definitions from this are used to inoculate the data graph. The graph URI is selected from a list of graphs of type owl:Ontology.

Inference

If enabled, OWL inferencing expansion of the data graph is performed before validation. Options are RDFS, OWLRL, Both, None. Default value: None.

Advanced

Enable SHACL Advanced Features. Default value: false.
