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)

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:

• The PREDEFINED_ONTOLOGIES global dictionary can now be used to map ontology IRI to arbitrary local pathes or URL.

• The new FTSSqlite3Phrase() string type can be used to perform FTS search using Sqlite3 special syntax, e.g. default_world.search(label = FTSSqlite3Phrase("Electrocardiographic OR ECG"))

• Add support for RDF plain literals, via the plainliteral Python datatype.

• Bugfixes: * Fix set_name() on property when python_name is the same as name * Fix some special characters (e.g. :) and keyword (e.g. OR) in FTS search * Fix literal with no datatype (should be considered as string, see https://www.w3.org/TR/rdf11-concepts/#section-Graph-Literal * Fix wrong inheritance of TransitiveProperty, ReflexiveProperty and SymmetricProperty * Fix 'DeprecationWarning: invalid escape sequence' in regexp * Raise an error when creating a new ontology inside a with ontology:... block * Use rdf:langString for locstr (was rdf:plainLiteral)

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

This version includes an observation framework allowing to register a listener to any entity, in order to be notified when the entity relations are modified.

It also introduces a new syntax for annotating relations: AnnotatedRelation(s,p,o).comment = ["abc"] (NB the old syntax remains supported).

Here are the changes:

• New syntax for annotations on relation, e.g. AnnotatedRelation(s,p,o).comment = "abc" (the old syntax remains supported)

• Optimize annotations on relations

• Support GRAPH clauses in SPARQL INSERT queries

• Observation framework (see owlready2.observe and doc on the observation framework)

• Bugfixes: - Fix the update of equivalent_to after destroying a class - Fix the update of annotations on class when modified with SPARQL queries - Fix SPARQL GRAPH clause in SELECT queries when querying the graph as a variable and all triples are not inside the GRAPH clause - Fix LANGMATCHES SPARQL function - Prevent multiprocessing loading of large ontologies when fork is not available (i.e. on Mac) - Fix subproperties parent classes when destroying a property - Fix loading of TransitiveProperty, SymmetricProperty, AsymmetricProperty, ReflexiveProperty, IrreflexiveProperty

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

This version includes a backward incompatible change: literal with different languages are now considered as different. For instance:

• locstr("Test", "en") != "Test"

• locstr("Test", "en") != locstr("Test", "fr")

This was not the case in previous releases, and it caused some weird bugs and confusion between literals.

I also would like to introduce a new projet: FullPy is Python module for designing web applications entirely in Python. It uses Owlready for data semantics and persistance. More information on FullPy can be found here:

• https://fullpy.readthedocs.io/en/latest/

Finally, due to a last minute bug, there is no 0.42 version.

Here are the changes:

• INCOMPATIBLE CHANGE: Consider literal with different language as different

• Support GRAPH clauses in SPARQL queries

• World now supports custom lock (e.g. World(lock = ...))

• Bugfixes: - Fix World(enable_thread_parallelism = True) (was named enable_gevent) - Fix blank nodes in rdflib_store - Fix FILTER in SPARQL when the filter was just after a recursive query - Fix recursive query in SPARQL involving variables in their right part - Fix SPARQL query with annotations containing entities - Fix property creation when using a Union in the '>>' syntax (e.g. class Prop((MyClass | MyOtherClass) >> str): pass) - Fix UMLS extraction in PyMedTermino2 - Fix Class IRI with brackets (or other special characters) when writing RDF/XML file

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

This version introduces some works on thread-based parallelization. The parsing of huge OWL file is now faster (about 25% faster on GO), and Owlready can execute SPARQL queries in parallel. Please refer to the doc for more info (https://owlready2.readthedocs.io/en/latest/sync.html).

Here are the changes:

• Parallelized huge OWL file parsing (about 25% faster on GO)

• Parallelized SPARQL queries (see owlready2.sparql.execute_many() and execute(spawn = True))

• Bugfixes: - Fix Class.INDIRECT_get_class_properties() with restriction on Inverse(Prop) - Fix Restriction of type HasSelf - Fix delattr in destroy_entity() - Fix blank nodes importation from RDFlib - Fix ', + and - in FTS search

Here are the changes:

• General class axiom support

• Update Log4J in Pellet for security purpose

• Add get_lang_first() for annotations.

• Bugfixes: - Add trailing / to ontology URL if missing - Fix Individual.is_a when loading ontologies with individuals belonging to two classes, one being the descendant of the other - Fix datetime to make them XSD-compatible (thanks Lukas Müller) - Ensure that Things are properly initialized so that the __init__ method can be safely overwritten (thanks Lukas Müller) - Fix destroy_entity()

Here are the changes:

• Make RDF triple deletion non-ontology-specific

• Faster creation of individual with property value (e.g. MyClass(prop = [value]))
