Interface IContextModel

All Superinterfaces:

IModel

public interface IContextModel

extends IModel

Represents a model of the context object as it defined in the context's ontology model. Since context's ontology model is defined in OWL DL format this interface is designed to simlify query and interpretation of the context's ontology model.

The URI returned by IModel.getType() could be used to retrieve an URL of the OWL ontology where this context's model is defined.
