Encapsulates a description of the components of an ontology model, including the storage scheme, reasoner and language profile.

Construct a new ontology model specification with the given specification parameters

Create one model spec as a copy of another.

Create an OntModel according to this model specification.

Answer a default specification for the given language URI.

Answer the document manager for this model specification.

Answer the URI of the ontology language to use when constructing models from this specification.

Create an OntModel according to this model specification.

Set the reasoner that will be used by ontology models that conform to this specification to compute entailments. Note: The reasoner is generated on demand by the reasoner factory.

Set the factory object that will be used to generate the reasoner object for this model specification.

Construct a new ontology model specification with the given specification parameters

Create one model spec as a copy of another. This is useful when what is required is similar to an existing spec, but with some changes. Note: this is only a shallow copy, so the structured objects (reasoners, document managers, etc) are not themselves copied. Thus, even after calling this copy constructor, making a change to the document manager in the copy specification will also affect the one that the copy was made from. The correct idiom is to replace the object before side-effecting it, e.g:

 OntModelSpec newSpec = new OntModelSpec( existingSpec );
 newSpec.setDocumentManager( new OntDocumentManager() );
 newSpec.getDocumentManager().setMetaDataSearchPath( "..." );
 

Create an OntModel according to this model specification. The base model comes from the attached base ModelMaker.

Answer a default specification for the given language URI. This default will typically use a memory model and have minimal inferencing capabilities. Specifically, OWL and RDFS languages will have RDFS level inferencing capability (chosen to give a reasonable balance between power and efficiency of computation), and DAML language will have the minimal DAML rule reasoner. To get other (more powerful or less powerful) reasoning capabilities, users should create ontology models by passing an explicit OntModelSpec parameter to the ModelFactory.createOntologyModel(OntModelSpecModel) model factory .

Answer the document manager for this model specification. Defaults to a standard instance of OntDocumentManager

Answer the URI of the ontology language to use when constructing models from this specification. Well known language URI's are available from the ProfileRegistry

Answer the language profile for this ontology specification

Answer the reasoner that will be used to infer additional entailed triples in the ontology model.

Answer the current reasoner factory

Create an OntModel according to this model specification. The base model comes from the underlying ModelMaker and is named by the given name.

Set the model maker used for base models.

Set the document manager in this specification

Set the model maker that will be used when the ontology model needs to create an additional container for an imported ontology

Set the URI of the ontology to use for models that conform to this specification.

Set the reasoner that will be used by ontology models that conform to this specification to compute entailments. Note: The reasoner is generated on demand by the reasoner factory. To prevent this spec from having a reasoner, set the reasoner factory to null, see OntModelSpec.setReasonerFactory .

Set the factory object that will be used to generate the reasoner object for this model specification. Note that the reasoner itself is cached, so setting the factory after a call to OntModelSpec.getReasoner() will have no effect.
