Method Detail

extractDirectSuperClassMap

public static Map<com.hp.hpl.jena.rdf.model.Resource,Set<com.hp.hpl.jena.rdf.model.Resource>> extractDirectSuperClassMap(com.hp.hpl.jena.rdf.model.Model model)

Extracts a mapping childClass -> parentClass from a given Model. You can use TransitiveClosure.transitiveClosure for "inferring" the whole hierarchy.

Parameters:

model -

Parameters:

model -

resource -

toString

public static String toString(com.hp.hpl.jena.rdf.model.Model model)

toString

public static String toString(com.hp.hpl.jena.rdf.model.Model model,
                              com.hp.hpl.jena.rdf.model.RDFWriter writer)

decompose

public static String[] decompose(String uri,
                                 NavigableMap<String,String> prefixMap)

An efficient method for separating a URI into namespace and prefix, given a set of arbitrary namespace prefixes. Note: This method is mainly intended for a nice representation, as a decomposition with arbitrary prefixes may not work with cerain RDF serializations. (e.g. with prefix p: becomes p:is/a/test)

Parameters:

uri -

prefixMap -

Returns:

prettyUri

public static String prettyUri(String uri,
                               NavigableMap<String,String> prefixMap)
