Method Detail

extract

public void extract(Vertex ontology,
                    Graph target)
             throws ExtractException

Extract the terms within a given ontology and copy them into a target graph.

Parameters:

ontology - The vertex representing the ontology to be extracted.

target - The target graph into which the elements of the ontology will be placed.

Throws:

ExtractException

shapeNamespaces

public Set<String> shapeNamespaces(Graph graph)

Get a list of the namespaces for shapes contained in a given graph.

Parameters:

graph - A graph containing sh:Shape nodes.

Returns:

The set of namespaces for all sh:Shape nodes in the graph.

collectOwlOntologies

public Set<String> collectOwlOntologies(Graph source,
                                        Set<String> exclude)

Collect OWL Ontologies from a given graph, but exclude those from a supplied set.

Parameters:

source - The source graph from which OWL Ontologies will be collected.

exclude - The set of IRI values for ontologies to be excluded.

Returns:

The OWL Ontologies from the source graph that are not referenced in the exclude set.

collectShapeOntologies

public void collectShapeOntologies(Graph source,
                                   Set<String> namespaceSet,
                                   Graph target)
