Parser

public Parser(com.hp.hpl.jena.rdf.model.Model model)

Instantiates a new parser.

Parameters:

model - is the Jena Model representation of a specified RDF document

Method Detail

subjectsOfType

public Map<String,String> subjectsOfType(String typeURI)
                                  throws RDFParserException

Subjects of type.

Parameters:

typeURI - of the RDF.type desired for

Returns:

Map of subjects (String keys are the URIs of the subjects)

Throws:

RDFParserException - if model is not initialized

getPropertyValues

public Map<String,String> getPropertyValues(String subjectURI,
                                            String propertyURI)
                                     throws RDFParserException

Gets the property values.

Parameters:

subjectURI - the subject uri

propertyURI - the property uri

Returns:

Map of property RDFNode values using URI or literal self as the key Default use of English or whatever is available(?)

Throws:

RDFParserException - if model is not initialized

getPropertyValues

public Map<String,String> getPropertyValues(String subjectURI,
                                            String propertyURI,
                                            Boolean fullId)
                                     throws RDFParserException

Gets the property values.

Parameters:

subjectURI - - target Subject Resource for query

propertyURI - - target Predicate (Property) for query

fullId - - set True if full Object lexical form or URI should be returned, otherwise, just the ontology term

Returns:

Map of property RDFNode values using URI or literal self as the key Default use of English or whatever is available(?)

Throws:

RDFParserException - if model is not initialized

getPropertyValues

public Map<String,String> getPropertyValues(String subjectURI,
                                            String propertyURI,
                                            String language,
                                            Boolean fullId)
                                     throws RDFParserException

Gets the property values.

Parameters:

subjectURI - the subject uri

propertyURI - the property uri

language - the language

fullId - - set True if full Object lexical form or URI should be returned, otherwise, just the ontology term

Returns:

Map of property RDFNode values using URI or literal self as the key

Throws:

RDFParserException - if model is not initialized

parseURI

public Map<String,String> parseURI(String uri)
                            throws RDFParserException

This method is a bit of a hack to repair URI's (incorrectly) abbreviated as QNames in the specified RDF model.

Parameters:

uri - the uri

Returns:

Map of namespace and full URI corresponding to QName, translated based on model recorded namespaces

Throws:

RDFParserException - if model is not initialized or if unknown QName encountered

fullURIMap

public Map<String,String> fullURIMap(Map<String,String> data_map)
                              throws RDFParserException

Method to rewrite the category keys into full URIs in case they are originally only XML QNames.

Parameters:

data_map - the data_map

Returns:

map with keys converted to full URI's

Throws:

RDFParserException - the RDF parser exception
