/**
*
* An enhanced view of a Jena model that is known to contain ontology
* data, under a given ontology {@link Profile vocabulary} (such as OWL).
* This class does not by itself compute the deductive extension of the graph
* under the semantic rules of the language. Instead, we wrap an underlying
* model with this ontology interface, that presents a convenience syntax for accessing
* the language elements. Depending on the inference capability of the underlying model,
* the OntModel will appear to contain more or less triples. For example, if
* this class is used to wrap a plain memory or database model, only the
* relationships asserted by the document will be reported through this
* convenience API. Alternatively, if the OntModel wraps an OWL inferencing model,
* the inferred triples from the extension will be reported as well. For
* example, assume the following ontology fragment:
*
* :A rdf:type owl:Class .
* :B rdf:type owl:Class ; rdfs:subClassOf :A .
* :widget rdf:type :B .
*
rdf:type of the widget will be
* reported as class :B only. In a model that can process the OWL
* semantics, the widget's types will include :B, :A,
* and owl:Thing.
*
*
* Note: that OntModel is an extension to the
* {@link InfModel} interface. This is to support the case where an ontology model
* wraps an inference graph, and we want to make the special capabilities of the
* InfModel, for example global consistency checking, accessible to
* client programs. Since not all ont models use a reasoner, using these methods
* may result in a runtime exception, though the typical behaviour is that such
* calls will be silently ignored.

*
* Note This method searches for nodes in the underlying model whose

* consequence of this is that in models without an attached reasoner (e.g. in the
* OWL_MEM {@link OntModelSpec}), the entailed type will not be present
* and this method will omit such properties from the returned iterator.
* Solution There are two
* ways to address to this issue: either use a reasoning engine to ensure that type entailments
* are taking place correctly, or call {@link #listAllOntProperties()}. Note
* that listAllOntProperties is potentially less efficient than this method.
