All known Subclasses: com.hp.hpl.jena.ontology.impl.OntModelImpl,
| OntModel | | public interface OntModel extends InfModel(Code) | |
An enhanced view of a Jena model that is known to contain ontology
data, under a given ontology
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
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.

which resource to create is the same as as the argument to the
RDFNode.as as() method: the Java class object of the desired abstraction. For example, to create an
ontology class via this mechanism, use:

This method requires that the separate download
owlsyntax.jar is on the Java classpath.
The three possible return values are
com.hp.hpl.jena.vocabulary.OWL.FULL_LANG FULL_LANG for OWL-full,
com.hp.hpl.jena.vocabulary.OWL.DL_LANG DL_LANG for OWL-DL or
com.hp.hpl.jena.vocabulary.OWL.LITE_LANG LITE_LANG for OWL-Lite.
Note that these URI's are not officially sanctioned by the WebOnt
working group. For unknown reasons, the working group chose not to assign official
URI's to represent the different OWL language levels. There is a slim chance that this
may change in future, in which case these return values will change appropriately.
In addition to the method return value,
the given problems list, if non-null, will be filled with the syntax
problems detected by the syntax checker.
The Jena OWL syntax checker will normally list as problems those constructs used in
this model that are in OWL Full but not permitted in OWL DL. The exception to this
is if the
for this model is
, then the syntax checker will
test for constructs that lie in OWL-DL or OWL-Full and hence outside in OWL-Lite.
Note that performing this test requires every statement in the model
to be examined, so it can be quite an expensive operation on large models, or on
persistent database models.

| listAllOntProperties | | public ExtendedIterator listAllOntProperties()(Code) | | Answer an iterator over all of the ontology properties in this model, including
object properties, datatype properties, annotation properties, etc. This method
takes a different approach to calculating the set of property resources to return,
and is robust against the absence of a reasoner attached to the model (see note
in

this method is potentially less efficient than the alternative listOntProperties().
Users whose models have an attached reasoner are recommended to use
OntModel.listOntProperties() .

An iterator of the root classes in the local class hierarchy |
| listImportedOntologyURIs | | public Set listImportedOntologyURIs()(Code) | |
Answer a list of the imported URI's in this ontology model. Detection of imports
statements will be according to the local language profile. Note that, in order to allow this
method to be called during the imports closure process, we only query the base model,
thus side-stepping the any attached reasoner.
The imported ontology URI's as a set. Note that since the underlying graph isnot ordered, the order of values in the list in successive calls to this method isnot guaranteed to be preserved. |
| listImportedOntologyURIs | | public Set listImportedOntologyURIs(boolean closure)(Code) | |
Answer a list of the imported URI's in this ontology model, and optionally in the closure
of this model's imports. Detection of imports
statements will be according to the local language profile. Note that, in order to allow this

thus side-stepping the any attached reasoner.
Parameters:
closure - If true, the set of URI's returned will include not only those directlyimported by this model, but those imported by the model's imports, and so on transitively.

Answer an iterator that ranges over the object property resources in this model, i.e.
the resources with rdf:type ObjectProperty or equivalent. An object
property is a property that is defined in the ontology language semantics as a
one whose range comprises individuals (rather than datatyped literals).
Specifically, the resources in this iterator will those whose type corresponds
to the value given in the ontology vocabulary associated with this model: see
Profile.OBJECT_PROPERTY .
An iterator over object property resources. |
| listOntProperties | | public ExtendedIterator listOntProperties()(Code) | |
Answer an iterator that ranges over the property resources in this model, i.e.
the resources with rdf:type Property or equivalent. An OntProperty
is equivalent to an rdfs:Property in a normal RDF graph; this type is
provided as a common super-type for the more specific
ObjectProperty and
DatatypeProperty property types.
Note This method searches for nodes in the underlying model whose
rdf:type is rdf:Property. This type is entailed by
specific property sub-types, such as owl:ObjectProperty. An important
consequence of this is that in models without an attached reasoner (e.g. in the
OWL_MEM
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
OntModel.listAllOntProperties() . Note
that listAllOntProperties is potentially less efficient than this method.
The resources returned by this iterator will those whose type corresponds
to the value given in the ontology vocabulary associated with this model.
An iterator over property resources. |
| listOntologies | | public ExtendedIterator listOntologies()(Code) | |
Answer an iterator that ranges over the ontology resources in this model, i.e.

in this model, i.e. resources with rdf:type
Restriction (or equivalent).
An iterator over restriction class resources.
See Also: Profile.RESTRICTION |
| listSubModels | | public ExtendedIterator listSubModels(boolean withImports)(Code) | | Answer an iterator over the ontology models that are sub-models of
this model. Sub-models are used, for example, to represent composite
documents such as the imports of a model. So if ontology A imports
ontologies B and C, each of B and C will be available as one of
the sub-models of the model containing A. This method replaces the
older
OntModel.listImportedModels . Note that to fully replicate
the behaviour of listImportedModels, the
withImports flag must be set to true. Each model
returned by this method will have been wrapped as an ontology model using the same
OntModelSpec as this model. If this model has no sub-models,
the returned iterator will be non-null but will not have any values.
Parameters:
withImports - If true, each sub-model returned by this methodwill also include its import models. So if model A imports D, and Dimports D, when called with withImports set to true, thereturn value for modelA.listSubModels(true) will be aniterator, whose only value is a model for D, and that model will containa sub-model representing the import of E. If withImportsis false, E will not be included as a sub-model of D. An iterator, each value of which will be an OntModelrepresenting a sub-model of this ontology. |
| listSubModels | | public ExtendedIterator listSubModels()(Code) | | Answer an iterator over the ontology models that are sub-models of
this model. Sub-models are used, for example, to represent composite
documents such as the imports of a model. So if ontology A imports
ontologies B and C, each of B and C will be available as one of
the sub-models of the model containing A.
Important note on behaviour change: please see
the comment on
OntModel.listSubModels(boolean) for explanation
of the withImports flag. This zero-argument form
of listSubModels sets withImports to
false, so the returned models will not themselves contain imports.
This behaviour differs from the zero-argument method
OntModel.listImportedModels() in Jena 2.4 an earlier.
An iterator, each value of which will be an OntModelrepresenting a sub-model of this ontology.

| listSymmetricProperties | | public ExtendedIterator listSymmetricProperties()(Code) | |
Answer an iterator that ranges over the symmetric property resources in this model, i.e.
the resources with rdf:type SymmetricProperty or equivalent.
Specifically, the resources in this iterator will those whose type corresponds
to the value given in the ontology vocabulary associated with this model: see
Profile.SYMMETRIC_PROPERTY .
An iterator over symmetric property resources. |
| listTransitiveProperties | | public ExtendedIterator listTransitiveProperties()(Code) | |
Answer an iterator that ranges over the transitive property resources in this model, i.e.
the resources with rdf:type TransitiveProperty or equivalent.
Specifically, the resources in this iterator will those whose type corresponds
to the value given in the ontology vocabulary associated with this model: see
Profile.TRANSITIVE_PROPERTY .
An iterator over transitive property resources. |
| listUnionClasses | | public ExtendedIterator listUnionClasses()(Code) | |
Answer an iterator that ranges over the union class-descriptions
in this model, i.e. the class resources specified to have a property
unionOf (or equivalent) and a list of values.
An iterator over union class resources.

| loadImports | | public void loadImports()(Code) | | Determine which models this model imports (by looking for, for example,
owl:imports statements, and load each of those models as an
import. A check is made to determine if a model has already been imported,
if so, the import is ignored. Thus this method is safe against circular
sets of import statements. Note that actual implementation is delegated to
the associated
OntDocumentManager .
|
| queryFor | | public ExtendedIterator queryFor(BindingQueryPlan query, List altQueries, Class asKey)(Code) | |
Answer the iterator over the resources from the graph that satisfy the given
query, followed by the answers to the alternative queries (if specified). A
typical scenario is that the main query gets resources of a given class (say,
rdfs:Class), while the altQueries query for aliases for that
type (such as daml:Class).
Parameters:
query - A query to run against the model
Parameters:
altQueries - An optional list of subsidiary queries to chain on to the first ExtendedIterator An iterator over the (assumed single) results ofexecuting the queries. |
| removeLoadedImport | | public void removeLoadedImport(String uri)(Code) | |
Record that this model no longer imports the document with the given
URI.
Parameters:
uri - A document URI that is no longer imported into the model. |
| removeSubModel | | public void removeSubModel(Model model)(Code) | |
Remove the given model as one of the sub-models of the enclosed ontology union model. Will
cause the associated inference engine (if any) to update, so this may be
an expensive operation in some cases.
Parameters:
model - A sub-model to remove
See Also: OntModel.addSubModel(Model,boolean) |
| removeSubModel | | public void removeSubModel(Model model, boolean rebind)(Code) | |
Remove the given model as one of the sub-models of the enclosed ontology union model.
Parameters:
model - A sub-model to remove
Parameters:
rebind - If true, rebind any associated inferencing engine to the new data (whichmay be an expensive operation) |
| setDynamicImports | | public void setDynamicImports(boolean dynamic)(Code) | | Set the flag that controls whether adding or removing imports
statements into the
model will result in the imports closure changing dynamically.
Parameters:
dynamic - If true, adding or removing an imports statement to themodel will result in a change in the imports closure. If false, changesto the imports are not monitored dynamically. Default false. |
| setStrictMode | | public void setStrictMode(boolean strict)(Code) | |
Set the checking mode to strict or non-strict.
Parameters:
strict -
See Also: OntModel.strictMode() |
| strictMode | | public boolean strictMode()(Code) | |
Answer true if this model is currently in strict checking mode. Strict
mode means
that converting a common resource to a particular language element, such as
an ontology class, will be subject to some simple syntactic-level checks for
appropriateness.
True if in strict checking mode |
| write | | public Model write(Writer writer)(Code) | | Write the model as an XML document.
It is often better to use an OutputStream rather than a Writer, since this
will avoid character encoding errors.
Note: This method is adapted for the ontology
model to write out only the base model (which contains the asserted data). To write
all triples, including imported data and inferred triples, use
OntModel.writeAll(Writer,String,String) writeAll .
