Interface ModelFactory<MC extends ModelConfiguration>

All Known Implementing Classes:

OWLArtModelFactory

public interface ModelFactory<MC extends ModelConfiguration>

OWLArt API do not deal too much with the details on how a Model implemented through different technologies may be generated. They just assume that the model has been loaded someway, and that it responds to the BaseRDFTripleModel interface.
However, this interface provides basic methods for loading models, so that it can be implemented (for each different technology which is adpted to OWL ART) for basic model creation

Contract for initialization methods contained in this class imposed that, if the loaded model is a persistent model and persistence information is found inside the specified persistence directory, then the model is started by retrieving all existing information
