public interface OntModel extends InfModel
An enhanced view of a Jena model that is known to contain ontology
data, under a given ontology 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:
In a non-inferencing model, the
: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.

com.hp.hpl.jena.util.iterator.ExtendedIterator<Ontology> listOntologies()
Answer an iterator that ranges over the ontology resources in this model, i.e.
the resources with rdf:type Ontology
or equivalent. These resources
typically contain metadata about the ontology document that contains them.
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.ONTOLOGY()
.
com.hp.hpl.jena.util.iterator.ExtendedIterator<OntProperty> listOntProperties()
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 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.
com.hp.hpl.jena.util.iterator.ExtendedIterator<OntProperty> listAllOntProperties()
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 listOntProperties()
for explanation). However, the calculation used by
this method is potentially less efficient than the alternative listOntProperties()
.
Users whose models have an attached reasoner are recommended to use
listOntProperties()
.

Answer a resource that represents a generic ontology node in this model. If a resource with the given URI exists in the model, it will be re-used. If not, a new one is created in the writable sub-model of the ontology model.
This is a generic method for creating any known ontology value. The selector that determines
which resource to create is the same as as the argument to the as()
method: the Java class object of the desired abstraction. For example, to create an
ontology class via this mechanism, use:
OntClass c = (OntClass) myModel.createOntResource( OntClass.class, null,
"http://example.org/ex#Parrot" );

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
.
Set<String> listImportedOntologyURIs()
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.
Set<String> listImportedOntologyURIs(boolean closure)
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
method to be called during the imports closure process, we only query the base model,
thus side-stepping the any attached reasoner.
closure
- If true, the set of URI's returned will include not only those directly
imported by this model, but those imported by the model's imports, and so on transitively.boolean hasLoadedImport(String uri)
Answer true if this model has had the given URI document imported into it. This is important to know since an import only occurs once, and we also want to be able to detect cycles of imports.

OntModel

,
listSubModels(boolean)
com.hp.hpl.jena.util.iterator.ExtendedIterator<OntModel> listSubModels(boolean withImports)
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 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.
withImports
- If true, each sub-model returned by this method
will also include its import models. So if model A imports D, and D
imports D, when called with withImports
set to true, the
return value for modelA.listSubModels(true)
will be an
iterator, whose only value is a model for D, and that model will contain
a sub-model representing the import of E. If withImports
is false, E will not be included as a sub-model of D.OntModel
representing a sub-model of this ontology.com.hp.hpl.jena.util.iterator.ExtendedIterator<OntModel> listSubModels()
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 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
listImportedModels()
in Jena 2.4 an earlier.

OntModel getImportedModel(String uri)
Answer an OntModel
representing the imported ontology
with the given URI. If an ontology with that URI has not been imported,
answer null.
uri
- The URI of an ontology that may have been imported into the
ontology represented by this modelModel getBaseModel()
Answer the base model of this model. The base model is the model
that contains the triples read from the source document for this
ontology. It is therefore this base model that will be updated if statements are
added to a model that is built from a union of documents (via the
imports
statements in the source document).
void addSubModel(Model model)
Add 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.
model
- A sub-model to addaddSubModel( Model, boolean )
void addSubModel(Model model, boolean rebind)
Add the given model as one of the sub-models of the enclosed ontology union model.

- A sub-model to addrebind
- If true, rebind any associated inferencing engine to the new data (which
may be an expensive operation)void removeSubModel(Model model)
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.

- A sub-model to removeaddSubModel( Model, boolean )
void removeSubModel(Model model, boolean rebind)
Remove the given model as one of the sub-models of the enclosed ontology union model.
model
- A sub-model to removerebind
- If true, rebind any associated inferencing engine to the new data (which
may be an expensive operation)boolean isInBaseModel(RDFNode node)
Answer true if the given node is a member of the base model of this ontology model. This is an important distinction, because only the base model receives updates when the ontology model is updated. Thus, removing properties of a resource that is not in the base model will not actually side-effect the overall model.
node
- An RDF node (Resource, Property or Literal) to testboolean isInBaseModel(Statement stmt)
Answer true if the given statement is defined in the base model of this ontology model. This is an important distinction, because only the base model receives updates when the ontology model is updated. Thus, removing a statement that is not in the base model will not actually side-effect the overall model.
stmt
- A statement to testboolean strictMode()
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.
void setStrictMode(boolean strict)
Set the checking mode to strict or non-strict.
strict
- strictMode()
void setDynamicImports(boolean dynamic)
Set the flag that controls whether adding or removing imports statements into the model will result in the imports closure changing dynamically.
dynamic
- If true, adding or removing an imports statement to the
model will result in a change in the imports closure. If false, changes
to the imports are not monitored dynamically. Default false.boolean getDynamicImports()
Answer true if the imports closure of the model will be dynamically updated as imports statements are added and removed.

Answer a reference to the document manager that this model is using to manage ontology <-> mappings, and to load the imports closure. Note by default, an ontology model is constructed with a reference to the shared, global document manager. Thus changing the settings via this model's document manager may affect other models also using the same instance.
OntModelSpec getSpecification()
Answer the ontology model specification that was used to construct this model
Model write(Writer writer)
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
writeAll
.
Model write(Writer writer, String lang)
Write a serialized representation of a model in a specified language.
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
writeAll
.
The language in which to write the model is specified by the
lang
argument. Predefined values are "RDF/XML",
"RDF/XML-ABBREV", "N-TRIPLE" and "N3". The default value,
represented by null
is "RDF/XML".
Model write(Writer writer, String lang, String base)

Model writeAll(Writer writer, String lang, String base)
Write a serialized representation of all of the contents of the model,
including inferred statements and statements imported from other
documents. To write only the data asserted in the base model, use
write
.
It is often better to use an OutputStream rather than a Writer,
since this will avoid character encoding errors.
The language in which to write the model is specified by the
lang
argument. Predefined values are "RDF/XML",
"RDF/XML-ABBREV", "N-TRIPLE" and "N3". The default value,
represented by null
, is "RDF/XML".
writer
- The output writerbase
- The base URI for relative URI calculations.
null
means use only absolute URI's.lang
- The language in which the RDF should be writtenModel writeAll(OutputStream out, String lang, String base)
Write a serialized representation of all of the contents of the model,
including inferred statements and statements imported from other
documents. To write only the data asserted in the base model, use
