Deprecated, for removal: This API element is subject to removal in a future version.
Use org.apache.jena.ontapi.

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: 

      :A rdf:type owl:Class .
      :B rdf:type owl:Class ; rdfs:subClassOf :A .
      :widget rdf:type :B .

In a non-inferencing model, the 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.

  • Method Details

    • listOntologies

      ExtendedIterator<Ontology> listOntologies()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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().

      Returns:
      An iterator over ontology resources.

    • listOntProperties

      ExtendedIterator<OntProperty> listOntProperties()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Returns:
      An iterator over property resources.

    • listAllOntProperties

      ExtendedIterator<OntProperty> listAllOntProperties()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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().

      Returns:
      An iterator over all available properties in a model, irrespective of whether a reasoner is available to perform rdf:type entailments. Each property will appear exactly once in the iterator.

    • listObjectProperties

      ExtendedIterator<ObjectProperty> listObjectProperties()
      Deprecated, for removal: This API element is subject to removal in a future version.

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().

      Returns:
      An iterator over object property resources.

    • loadImports

      void loadImports()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      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.

      Returns:
      The imported ontology URI's as a set. Note that since the underlying graph is not ordered, the order of values in the list in successive calls to this method is not guaranteed to be preserved.

      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Parameters:
      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.
      Returns:
      A set of imported ontology URIs. Note that since the underlying graph is not ordered, the order of values in the list in successive calls to this method is not guaranteed to be preserved.

    • hasLoadedImport

      boolean hasLoadedImport(String uri)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

    • listSubModels

      ExtendedIterator<OntModel> listSubModels(boolean withImports)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Parameters:
      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 E, 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.
      Returns:
      An iterator, each value of which will be an OntModel representing a sub-model of this ontology.

      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Returns:
      An iterator, each value of which will be an OntModel representing a sub-model of this ontology.

    • countSubModels

      int countSubModels()
      Deprecated, for removal: This API element is subject to removal in a future version.

      Answer the number of sub-models of this model, not including the base model.

      Returns:
      The number of sub-models, ≥ zero.

    • getImportedModel

      OntModel getImportedModel(String uri)
      Deprecated, for removal: This API element is subject to removal in a future version.

      Answer an OntModel representing the imported ontology with the given URI. If an ontology with that URI has not been imported, answer null.

      Parameters:
      uri - The URI of an ontology that may have been imported into the ontology represented by this model
      Returns:
      A model representing the imported ontology with the given URI, or null.

    • getBaseModel

      Model getBaseModel()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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).

      Returns:
      The base model for this ontology model

    • addSubModel

      void addSubModel(Model model)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Parameters:
      model - A sub-model to add
      See Also:

    • addSubModel

      void addSubModel(Model model, boolean rebind)
      Deprecated, for removal: This API element is subject to removal in a future version.

      Add the given model as one of the sub-models of the enclosed ontology union model.

      Parameters:
      model - A sub-model to add
      rebind - If true, rebind any associated inferencing engine to the new data (which may be an expensive operation)

    • removeSubModel

      void removeSubModel(Model model)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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:

    • removeSubModel

      void removeSubModel(Model model, boolean rebind)
      Deprecated, for removal: This API element is subject to removal in a future version.

      Remove the given model as one of the sub-models of the enclosed ontology union model.

      Parameters:
      model - A sub-model to remove
      rebind - If true, rebind any associated inferencing engine to the new data (which may be an expensive operation)

    • isInBaseModel

      boolean isInBaseModel(RDFNode node)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Parameters:
      node - An RDF node (Resource, Property or Literal) to test
      Returns:
      True if the given node is from the base model

    • isInBaseModel

      boolean isInBaseModel(Statement stmt)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Parameters:
      stmt - A statement to test
      Returns:
      True if the given statement is from the base model

    • strictMode

      boolean strictMode()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Returns:
      True if in strict checking mode

    • setStrictMode

      void setStrictMode(boolean strict)
      Deprecated, for removal: This API element is subject to removal in a future version.

      Set the checking mode to strict or non-strict.

      Parameters:
      strict -
      See Also:

    • setDynamicImports

      void setDynamicImports(boolean dynamic)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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 the model will result in a change in the imports closure. If false, changes to the imports are not monitored dynamically. Default false.

    • getDynamicImports

      boolean getDynamicImports()
      Deprecated, for removal: This API element is subject to removal in a future version.

      Answer true if the imports closure of the model will be dynamically updated as imports statements are added and removed.

      Returns:
      True if the imports closure is updated dynamically.

    • getDocumentManager

      OntDocumentManager getDocumentManager()
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.

      Returns:
      A reference to this model's document manager

    • getSpecification

      OntModelSpec getSpecification()
      Deprecated, for removal: This API element is subject to removal in a future version.

      Answer the ontology model specification that was used to construct this model

      Returns:
      An ont model spec instance.

    • write

      Model write(Writer writer)
      Deprecated, for removal: This API element is subject to removal in a future version.

      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.
