Module Contents

class owlapy.owl_ontology_manager.OWLImportsDeclaration(import_iri: owlapy.iri.IRI)

Bases: owlapy.meta_classes.HasIRI

Represents an import statement in an ontology.

__slots__ = '_iri'

property iri: owlapy.iri.IRI

Gets the import IRI.

Returns:

The import IRI that points to the ontology to be imported. The imported ontology might have this IRI as its ontology IRI but this is not mandated. For example, an ontology with a non-resolvable ontology IRI can be deployed at a resolvable URL.

property str: str

Gets the string representation of this object

Returns:

The IRI as string

class owlapy.owl_ontology_manager.AddImport(ontology: owlapy.abstracts.abstract_owl_ontology.AbstractOWLOntology, import_declaration: OWLImportsDeclaration)

Bases: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyChange

Represents an ontology change where an import statement is added to an ontology.

__slots__ = ('_ont', '_declaration')

get_import_declaration() → OWLImportsDeclaration

Gets the import declaration that the change pertains to.

Returns:

The import declaration.

class owlapy.owl_ontology_manager.OntologyManager(world_store=None)

Bases: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyManager

An OWLOntologyManager manages a set of ontologies. It is the main point for creating, loading and accessing ontologies.

__slots__ = '_world'

create_ontology(iri: str | owlapy.iri.IRI = None) → owlapy.owl_ontology.Ontology

Creates a new (empty) ontology that that has the specified ontology IRI (and no version IRI).

Parameters:

iri – The IRI of the ontology to be created, can also be a string.

Returns:

The newly created ontology.

load_ontology(path: str = None) → owlapy.owl_ontology.Ontology

Loads an ontology that is assumed to have the specified ontology IRI as its IRI or version IRI. The ontology IRI will be mapped to an ontology document IRI.

Parameters:

iri –

The IRI that identifies the ontology, can also be a string.

It is expected that the ontology will also have this IRI

(although the OWL API should tolerate situations where this is not the case).

Returns:

The OWLOntology representation of the ontology that was loaded.

apply_change(change: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyChange)

A convenience method that applies just one change to an ontology. When this method is used through an OWLOntologyManager implementation, the instance used should be the one that the ontology returns through the get_owl_ontology_manager() call.

Parameters:

change – The change to be applied.

Raises:

ChangeApplied.UNSUCCESSFULLY – if the change was not applied successfully.

save_world()

Saves the actual state of the quadstore in the SQLite3 file.

class owlapy.owl_ontology_manager.SyncOntologyManager

Bases: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyManager

Create OWLManager in Python https://owlcs.github.io/owlapi/apidocs_5/org/semanticweb/owlapi/apibinding/OWLManager.html

owlapi_manager

create_ontology(iri: owlapy.iri.IRI | str) → owlapy.owl_ontology.SyncOntology

Creates a new (empty) ontology that that has the specified ontology IRI (and no version IRI).

Parameters:

iri – The IRI of the ontology to be created, can also be a string.

Returns:

The newly created ontology.

load_ontology(path: str) → owlapy.owl_ontology.SyncOntology

Loads an ontology that is assumed to have the specified ontology IRI as its IRI or version IRI. The ontology IRI will be mapped to an ontology document IRI.

Parameters:

iri –

The IRI that identifies the ontology, can also be a string.

It is expected that the ontology will also have this IRI

(although the OWL API should tolerate situations where this is not the case).

Returns:

The OWLOntology representation of the ontology that was loaded.

get_owlapi_manager()

abstract apply_change(change: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyChange)

A convenience method that applies just one change to an ontology. When this method is used through an OWLOntologyManager implementation, the instance used should be the one that the ontology returns through the get_owl_ontology_manager() call.

Parameters:

change – The change to be applied.

Raises:

ChangeApplied.UNSUCCESSFULLY – if the change was not applied successfully.

getOntologyFormat(*args)

saveOntology(*args) → None

class owlapy.owl_ontology_manager.RDFLibOntologyManager

Bases: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyManager

An OWLOntologyManager manages a set of ontologies. It is the main point for creating, loading and accessing ontologies.

create_ontology(iri: str = None) → owlapy.owl_ontology.RDFLibOntology

Creates a new (empty) ontology that that has the specified ontology IRI (and no version IRI).

Parameters:

iri – The IRI of the ontology to be created, can also be a string.

Returns:

The newly created ontology.

load_ontology(path: str = None) → owlapy.owl_ontology.Ontology

Loads an ontology that is assumed to have the specified ontology IRI as its IRI or version IRI. The ontology IRI will be mapped to an ontology document IRI.

Parameters:

iri –

The IRI that identifies the ontology, can also be a string.

It is expected that the ontology will also have this IRI

(although the OWL API should tolerate situations where this is not the case).

Returns:

The OWLOntology representation of the ontology that was loaded.

abstract apply_change(change: owlapy.abstracts.abstract_owl_ontology_manager.AbstractOWLOntologyChange)

A convenience method that applies just one change to an ontology. When this method is used through an OWLOntologyManager implementation, the instance used should be the one that the ontology returns through the get_owl_ontology_manager() call.

Parameters:

change – The change to be applied.

Raises:

ChangeApplied.UNSUCCESSFULLY – if the change was not applied successfully.
