Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new realease fixes several bugs and now includes Pellet 2.3.1 (same version as in Protégé) instead of version 2.4 (which seems to have problems with some SWRL builtins).

Here are the changes:

• Use Pellet 2.3.1 (same version as Protégé) instead of 2.4 (which has a bug in SWRL for many builtin predicates including equals and matches)

• Much faster mangement of annotations on relations

• Bugfixes: - Fix bug on blank node in RDFlib/SPARQL support - Fix bug on blank node deletion in RDFlib/SPARQL support - Fix data loss in Restriction modification - Fix 'no query solution' error in search() - Fix literal support in RDF lists, causing "TypeError: '<' not supported between instances of 'NoneType' and 'int'" when saving ontologies - Fix DifferentFrom SWRL builtin - Fix string parsing in SWRL rules - Fix string and boolean literal representation (str/repr) in SWRL rules - Fix the inverse of subproperties having a symmetric superproperty

My French book "Python et les ontologies" has been published by ENI editions.

This 310-pages book describes how to use OWL 2.0 ontologies in Python 3.x, with the Owlready2 Python module for ontology-oriented programming.

More informations (in French) on the editor website:

I plan to translate the book in English in the coming year.

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new version fix an important bug in UMLS support.

It also stops considering as functional properties associated with exactly-1 or max-1 restrictions. This was intended to be a feature, but was actually often more annoying that desirable. If needed, you can restore the previous behaviour as follows:

import owlready2.prop
owlready2.prop.RESTRICTIONS_AS_FUNCTIONAL_PROPERTIES = True

Here are the changes:

• Add support for undoable destroy_entity()

• Small database optimizations

• No longer treat properties associated with exactly-1 or max-1 restriction as functional properties, returning single values instead of a list

• Bugfixes: - Fix performance bug on UMLS mapping in PyMedTermino

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new version has a better SPARQL support, faster searches, and it adds the "individual.INVERSE_property" syntax. It also supports the new UMLS zipped file format.

Here are the changes:

• Consider symmetric properties as their own inverse properties

• Update Python objects after basic SPARQL update/delete queries (works on user-defined properties, hierarchical properties (type/subclassof) and equivalence properties)

• Add individual.INVERSE_property

• Add Class.INDIRECT_is_a

• INDIRECT_is_a / INDIRECT_is_instance_of now include class contructs. ancestors() has a 'include_constructs' parameter, which defaults to False.

• Add more aliases for XMLSchema datatypes

• Add is_a property to class constructs

• Add bottomObjectProperty and bottomDataProperty

• Support ReflexiveProperties in individual.INDIRECT_property

• Optimize Thing.subclasses()

• Optimize search() with multiple criteria, including those done by PyMedTermino

• Add support for destroy_entity(SWRL_rule)

• Add support for UMLS "metathesaurus" format in addition to "full" format

• Bugfixes: - After reasoning, keep all equivalent classes as parents of individuals (as they may have methods) - Fix IndividualPropertyAtom when creating SWRL rule - Fix SWRL parser - Fix RDF serialization for nested RDF lists - Fix removing inverse property (i.e. Prop.inverse = None) - Fix datetime parsing for date with time zone or milliseconds

Here are the changes:

• Add UNIQUE constraints for preventing dupplicated RDF triples in the quadstore

• Add Individual.INDIRECT_is_a / Individual.INDIRECT_is_instance_of

• Add isinstance_python() (faster than isinstance(), but do not consider equivalent_to relations)

• Bugfixes: - Force UTF-8 encoding when importing UMLS - Be more tolerant when loading OWL file

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new version adds the ability to infer property values (as in Protégé) and to use SWRL rules. It improves class properties and it can import UMLS (still undocumentated!). It also fixes several bugs.

Here are the changes in version 0.14:

• UMLS support (owlready2.pymedtermino2 package)

• Can infer object property values when reasoning (thanks W Zimmer)

• New implementation of property values; use INDIRECT_prop to get indirect values

• Support several class property types : some, only, some + only, and direct relation

• Automatically create defined classes via class properties

• Support anonymous individuals, e.g. Thing(0)

• Optimize search() when only the number of returned elements is used

• Optimize FTS search() when using also non-FTS statements

• Can restrict reasoning to a list of ontologies

• Union searches (i.e. default_world.search(...) | default_world.search(...))

• Bugfixes: - Fix functional class properties with inheritance - Fix dupplicated instance list restrictions when calling close_world(ontology) - Fix use of '*' in search - Fix synchronization, using contextvars for global variables

Owlready is a Python module for ontology-oriented programming. It can load OWL 2.0 ontologies and manipulate them transparently in Python.

This new major version uses a new quadstore, with better performances, and has been tested up to 200 millions of RDF triplets (can load DBpedia!). PostgresQL support has been dropped because its interest was very limited (performances were poor compared to Sqlite3).

Here are the changes in version 0.12:

• New quadstore

• Numerical search (NumS, e.g. all patients with age > 65)

• Nested searches

• Synchronization for multithreading support

• Add Class.inverse_restrictions() and Class.direct_instances()

• Drop PostgresQL support (little interest: more complex and slower than Sqlite3)

• Bugfixes: - Fix call to _get_by_storid2 - Fix rdfs_subclassof in doc - Fix FTS triggers - Fix boolean in RDFlib / SPARQL - Fix bug when destroying an AnnotationProperty
