public RDFOntologyFormat()

Method Detail

isAddMissingTypes

public boolean isAddMissingTypes()

Determines if untyped entities should automatically be typed (declared) during rendering. (This is a hint to an RDF renderer - the reference implementation will respect this). The render will check with the isMissingType(org.semanticweb.owlapi.model.OWLEntity, org.semanticweb.owlapi.model.OWLOntology) method to determine if it needs to add a type.

Returns:

true if untyped entities should automatically be typed during rendering, otherwise false.

isMissingType

public static boolean isMissingType(OWLEntity entity,
                                    OWLOntology ontology)

Determines if a declaration axiom (type triple) needs to be added to the specified ontology for the given entity.

Parameters:

entity - The entity

ontology - The ontology.

Returns:

false if the entity is built in. false if the ontology doesn't contain the entity in its signature. false if the entity is already declared in the imports closure of the ontology. false if the transitive imports does not contain the ontology but the entity is contained in the signature of one of the imported ontologies, true if none of the previous conditions are met.

setAddMissingTypes

public void setAddMissingTypes(boolean addMissingTypes)

Determines if untyped entities should automatically be typed during rendering. By default this is true.

Parameters:

addMissingTypes - true if untyped entities should automatically be typed during rendering, otherwise false.

getOntologyLoaderMetaData

public RDFParserMetaData getOntologyLoaderMetaData()

Description copied from class: OWLOntologyFormat

If this format describes an ontology that was loaded from some ontology document (rather than created programmatically) there may be some meta data about the loading process. Subclasses of OWLOntologyFormat will provide accessors etc. to details pertaining to the meta data about loading.

Overrides:

getOntologyLoaderMetaData in class OWLOntologyFormat

Returns:

An object containing the meta data about loading. Not null.

addError

public void addError(RDFResourceParseError error)

Parameters:

error - error to add to the error set
