Method Detail

getConciseBoundedDescription

public org.apache.jena.rdf.model.Model getConciseBoundedDescription(String resourceURI)

Description copied from interface: ConciseBoundedDescriptionGenerator

Computes the CBD (of depth 1) for the given resource.

Specified by:

getConciseBoundedDescription in interface ConciseBoundedDescriptionGenerator

Parameters:

resourceURI - the resource URI

Returns:

the CBD

getConciseBoundedDescription

public org.apache.jena.rdf.model.Model getConciseBoundedDescription(String resource,
                                                                    int depth)

Description copied from interface: ConciseBoundedDescriptionGenerator

Computes the CBD of given depth for the given resource.

Specified by:

getConciseBoundedDescription in interface ConciseBoundedDescriptionGenerator

Parameters:

resource - the resource URI

depth - the max. depth of the CBD

Returns:

the CBD

getConciseBoundedDescription

public org.apache.jena.rdf.model.Model getConciseBoundedDescription(String resource,
                                                                    int depth,
                                                                    boolean withTypesForLeafs)

Description copied from interface: ConciseBoundedDescriptionGenerator

Computes the CBD of given depth for the given resource. Optionally, additional information about the types for the leaf nodes is retrieved.

Specified by:

getConciseBoundedDescription in interface ConciseBoundedDescriptionGenerator

Parameters:

resource - the resource URI

depth - the max. depth of the CBD

withTypesForLeafs - whether to get the types of the leaf nodes

Returns:

the CBD

setIgnoredProperties

public void setIgnoredProperties(Set<String> properties)

Description copied from interface: ConciseBoundedDescriptionGenerator

Set the properties allowed to occur in triples of the generated CBD. Filtering can happen either remotely via SPARQL queries or might be implemented locally via post-processing on the retrieved triples.

Specified by:

setIgnoredProperties in interface ConciseBoundedDescriptionGenerator

Parameters:

properties - the ignored properties

setAllowedPropertyNamespaces

public void setAllowedPropertyNamespaces(Set<String> namespaces)

Description copied from interface: ConciseBoundedDescriptionGenerator

Set the property namespaces allowed to occur in triples of the generated CBD. Filtering can happen either remotely via SPARQL queries or might be implemented locally via post-processing on the retrieved triples.

Specified by:

setAllowedPropertyNamespaces in interface ConciseBoundedDescriptionGenerator

Parameters:

namespaces - the allowed property namespaces

setAllowedObjectNamespaces

public void setAllowedObjectNamespaces(Set<String> namespaces)

Description copied from interface: ConciseBoundedDescriptionGenerator

Set the allowed namespaces for resources occuring in object position of the retrieved triples. Filtering can happen either remotely via SPARQL queries or might be implemented locally via post-processing on the retrieved triples.

Specified by:

setAllowedObjectNamespaces in interface ConciseBoundedDescriptionGenerator

Parameters:

namespaces - the allowed namespaces

main

public static void main(String[] args)
