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

This new release includes several small changes and bugfixes. It now uses the Git versionning system, instead of Mercurial.

Here are the changes:

• Support intersection of searches (e.g. World.search(...) & World.search(...))

• Add owlready2.reasoning.JAVA_MEMORY

• Move development repository to Git

• Bugfixes: - Fix parsing of NTriples files that do not end with a new line - Fix KeyError with Prop.python_name when several properties share the same name - Fix get_ontology() calls in Python module imported by ontologies in a World that is not default_world - Fix use of PyMedTermino2 in a World that is not default_world - Fix World.as_rdflib_graph().get_context(onto) for ontology added after the creation of the RDFLIB graph - Fix destroying SWRL rules - Fix disjoint with non-atomic classes

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

This new release includes several small changes and bugfixes.

Here are the changes:

• Add get_parents_of(), get_instances_of(), get_children_of() methods to ontology, for querying the hierarchical relations defined in a given ontology

• Use Thing as default value for restrictions with number, instead of None

• Add 'filter' parameter to save(), for filtering the entities saved (contributed by Javier de la Rosa)

• Bugfixes: - Fix value restriction with the false value - Fix blank node loading from different ontologies - Fix constructs reused by several classes - Fix 'Class.is_a = []' was not turning the list into an Owlready list - Fix destroy_entity() - was not destroying the IRI of the entity - Improve setup.py: ignore Cython if Cython installation fails

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

Here are the changes:

• Add support for disjoint unions (Class.disjoint_unions)

• Add deepcopy support on class constructs, and automatically deep-copy constructs when needed (i.e. no more OwlReadySharedBlankNodeError)

• Support the creation of blank nodes with RDFlib

I presented my works on visual decision support for breast cancer therapy, at the ICABME 2019 congress in Tripoli.

My paper was entitled "Hierarchical visual case-based reasoning for supporting breast cancer therapy". It is available here and the presentation there.

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

I presented my works on the use of icons for browsing medical terminologies, in particular in pharmacovigilance, at MEDINFO 2019.

My paper was entitled "An iconic approach to the browsing of medical terminologies". It is available here and the presentation there.

And I obtained the Best paper award (first place)!

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
