Owlready2 est un module Python pour la programmation orientée ontologie. Il permet de charger des ontologies OWL 2.0 et de les manipuler de manière transparente en Python.

Voici les modifications :

• Support xsd:duration, including DATETIME_DIFF(), DATETIME_ADD(), DATETIME_SUB() SPARQL non-standard functions

• Faster ontology operation (e.g. ontology deletion) on big quadstores

• Automatically add .owl, .rdf or .xml to ontology IRI if the IRI itself does not yield an OWL file

• Bugfixes: - Fix FusionClasses (= individuals belonging to several classes, i.e. multiple instanciation) when using several worlds - Fix OPTIONAL SPARQL clause when guessing variable types - Fix typo in undo entity destruction (thanks Lukas Westhofen) - Fix IRI from OWL namespace in SWRL rules - Fix Pellet explanation on inconsistent ontology - Fix MEDDRA parent-child relation of LLT in PyMedTermino2 - Make sure the filename is a file before returning (Thanks Nicolas Rouquette)

Owlready2 est un module Python pour la programmation orientée ontologie. Il permet de charger des ontologies OWL 2.0 et de les manipuler de manière transparente en Python.

Voici les modifications :

• SPARQL optimizations

• Support for VALUES in SPARQL

• Add STATIC optimization keyword extension to SPARQL

• Accept GROUP BY, HAVING, LIMIT in INSERT and DELETE SPARQL query

• Add the STORID(iri), DATE(), TIME() and DATETIME() SPARQL function

• UMLS CUI are now hierarchized by Semnatic Types (TUI)

• Improved parallelism

• Bugfixes: - Fix 'sqlite3.OperationalError: circular reference: prelim1_objs' in .instances(), caused by a bug in old versions of SQLite3 - Fix SPARQL INSERT query with data parameters in the INSERT clause - Fix RDF list parsing when the list includes the integer number 5 - Fix nb_parameter in SPARQL query when numbered parameters are used - Fix ObjectProperty.subclasses(), ObjectProperty.descendants(), Property.subclasses(), DataProperty.descendants(), AnnotationProperty.subclasses(), AnnotationProperty.descendants() - Fix declare_datatype() for datatype already used in Owlready, such as AnyURI - Fix Pellet on properties having annotations that are not declared in the loaded ontologies

Voici les modifications :

• NEW FORUM ADDRESS: http://owlready.306.s1.nabble.com

• Support SPARQL property path expressions with parentheses without sequences, repeats or negative property set nested inside repeats

• Add define_datatype_in_ontology() global function for defining a new user-defined datatype in an ontology

• Class.instances() now takes into account equivalent classes (like other class methods such as .descendants())

• Add the LOADED(iri) SPARQL function

• Support Thing.is_a.append(...)

• Faster loading of very large quadstores

• list(onto.metadata) now lists the annotations present on the ontology

• Add OntologyClass and NamespaceClass argument to get_ontology() and get_namespace(), allowing the use of custom classes

• Bugfixes: - Accept UTF8 and latin encoding from reasoners (thanks Francesco Compagno) - Fix SPARQL query with a UNION without variables - Fix semantic type support in UMLS
