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 includes optimizations, bugfixes, and improvement in SPARQL and terminology management.

Here are the changes:

• Faster ontology loading (espescially when having a lot of small ontologies)

• Add support for Full Text Search (FTS) in SPARQL (see FTS() SPARQL function)

• Accept list as parameter in SPARQL queries when using the IN operator

• Make prepared SPARQL queries picklable

• Support DELETE SPARQL queries with free variables in the DELETE part

• Improve DELETE SPARQL queries in order to delete IRI/storid of entirely deleted entities

• Add support for SNOMED CT French translation in PyMedTermino2

• Add function owlready2.pymedtermino2.umls.prune() to prune terminologies to the descendants of the given concepts

• Add add_terminology() and add_term() methods in owlready2.pymedtermino2

• Add owlready2.pymedtermino2.model.TerminologySearcher for fast search in terminologies

• Bugfixes:

  • Fix RDF parsing of axiom with restriction in the optimized C-compiled module.

  • Properly close database when a World is destroyed

  • Use requests module for importing French ICD10 (urllib does not work)

  • Fix SPARQL query with fixed parameters

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:

• Support binary data: Python bytes are now mapped to XML base64Binary.

• Bugfixes:

  • Fix OPTIONAL blocks in SPARQL queries that share variable outside the OPTIONAL block

  • Fix prop1[prop2 in OPTIONAL blocks in SPARQL queries

  • Fix individuals belonging to several classes when one of these classes has a OneOf construct including that individual

  • Fix descendants when using subclasses of ThingClass (as PyMedTermino2 does)

  • Fix and update pymedtermino2

  • Fix SPARQL queries with BIND and UNION

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:

• Remove warning when Cython module is not available

• Update import OMOP CDM for their new CSV format

• Basic support for enumerated datatypes (= defined with an equivalent_to and a OneOf)

• Improved synchronization and multiprocessor support

• Bugfixes: * Fix IRI() return type in SPARQL * Fix SPARQL queries with two UNIONs when there is no shared variables between the unions members * Fix parsing ontology with IRI ending by '?' * Avoid reusing ID of destroyed entity (storid; reuse is problematic when sharing the quadstore with other processes)
