public JsonLdRDF()

Method Detail

asDataset

public JsonLdDataset asDataset(com.github.jsonldjava.core.RDFDataset rdfDataSet)

Adapt a JsonLd RDFDataset as a Commons RDF Dataset.

Changes to the Commons RDF Dataset are reflected in the JsonLd RDFDataset and vice versa.

Parameters:

rdfDataSet - JsonLd RDFDataset to adapt

Returns:

Adapted Dataset

See Also:

asGraph(RDFDataset)

asGraph

public JsonLdGraph asGraph(com.github.jsonldjava.core.RDFDataset rdfDataSet)

Adapt a JsonLd RDFDataset as a Commons RDF Graph.

Only triples in the default graph are included. To retrieve any other graph, asDataset(RDFDataset) together with Dataset.getGraph(BlankNodeOrIRI).

Changes to the Commons RDF Graph are reflected in the JsonLd RDFDataset and vice versa.

Parameters:

rdfDataSet - JsonLd RDFDataset to adapt

Returns:

Adapted Graph covering the default graph

See Also:

asDataset(RDFDataset), asUnionGraph(RDFDataset)

asJsonLdNode

public com.github.jsonldjava.core.RDFDataset.Node asJsonLdNode(RDFTerm term)

asJsonLdQuad

public com.github.jsonldjava.core.RDFDataset.Quad asJsonLdQuad(Quad quad)

Adapt a Commons RDF Quad as a JsonLd RDFDataset.Quad.

Parameters:

quad - Commons RDF Quad to adapt

Returns:

Adapted JsonLd RDFDataset.Quad

asJsonLdQuad

public com.github.jsonldjava.core.RDFDataset.Quad asJsonLdQuad(Triple triple)

Adapt a Commons RDF Triple as a JsonLd RDFDataset.Quad.

Parameters:

triple - Commons RDF Triple to adapt

Returns:

Adapted JsonLd RDFDataset.Quad

asQuad

public JsonLdQuad asQuad(com.github.jsonldjava.core.RDFDataset.Quad quad)

Adapt a JsonLd RDFDataset.Quad as a Commons RDF Quad.

The underlying JsonLd quad can be retrieved with JsonLdTripleLike.asJsonLdQuad().

Parameters:

quad - A JsonLd RDFDataset.Quad to adapt

Returns:

Adapted JsonLdQuad

asRDFTerm

public JsonLdTerm asRDFTerm(com.github.jsonldjava.core.RDFDataset.Node node)

Adapt a JsonLd RDFDataset.Node as a Commons RDF RDFTerm.

The underlying node can be retrieved with JsonLdTerm.asJsonLdNode().

Parameters:

node - A JsonLd RDFDataset.Node to adapt

Returns:

Adapted JsonLdTerm

asTriple

public JsonLdTriple asTriple(com.github.jsonldjava.core.RDFDataset.Quad quad)

Adapt a JsonLd RDFDataset.Quad as a Commons RDF Triple.

The underlying JsonLd quad can be retrieved with JsonLdTripleLike.asJsonLdQuad().

Parameters:

quad - A JsonLd RDFDataset.Quad to adapt

Returns:

Adapted JsonLdTriple

asUnionGraph

public JsonLdUnionGraph asUnionGraph(com.github.jsonldjava.core.RDFDataset rdfDataSet)

Adapt a JsonLd RDFDataset as a Commons RDF Graph.

The graph can be seen as a union graph as it will contains all the triples across all the graphs of the underlying RDFDataset.

Note that some triple operations on a union graph can be inefficient as they need to remove any duplicate triples across the graphs.

Changes to the Commons RDF Graph are reflected in the JsonLd RDFDataset and vice versa. Triples removed from the graph are removed from all graphs, while triples added are added to the default graph.

Parameters:

rdfDataSet - JsonLd RDFDataset to adapt

Returns:

Adapted Dataset
