Examples of org.mindswap.pellet.KBLoader

org.mindswap.pellet.KBLoader

A generic class that allows the creation of Pellet KnowledgeBase instances and load ontologies. The actual parsing and loading operations is implemented by the concrete extensions of this class where each implementation uses a different parser and loader, e.g. Jena or OWLAPI.

Loading to a KnowledgeBase instance is typically a two-phase process. First the ontology is parsed into a representation supported by the loader, e.g. Jena Model or OWLAPI Ontology. Then this object is processed by Pellet and loaded to the KnowledgeBase class.

This class provides fined-grained control over how parsing and loading is done along with a convenience function to do everything at once. Concrete implementations of this class provides access to the ontology object used by the underlying loader.
