Class Method Details

.execute(input, queryable = nil, **options) ⇒ Hash{RDF::Term => Array<ValidationResult>}, SHACL::ValidationReport

The Shapes Graph, is established similar to the Data Graph, but may be nil. If nil, the Data Graph may reference a Shapes Graph thorugh an sh:shapesGraph property.

Additionally, a Shapes Graph may contain an owl:imports property referencing additional Shapes Graphs, which are resolved until no more imports are found.

Load and validate the given SHACL expression string against queriable.

Parameters:

  • input (String, IO, StringIO, #to_s)
  • queryable (RDF::Queryable) (defaults to: nil)
  • options (Hash{Symbol => Object})

Returns:

    self.open(input, **options)
  else
    Shapes.from_queryable(queryable)
  end

  shapes.execute(queryable, **options)
end

.from_queryable(queryable, **options) ⇒ Object

Retrieve shapes from a sh:shapesGraph reference within queryable

  Shapes.from_queryable(queryable, **options)
end

.get_shapes(shapes_graph, **options) ⇒ Object

Transform the given Shapes Graph into a set of executable shapes.

A Shapes Graph may contain an owl:imports property referencing additional Shapes Graphs, which are resolved until no more imports are found.

Parameters:

  • input (String, IO, StringIO, #to_s)
