Owlready2 0.22 has been released!

[Jiba]

Hi everybody,

This new release adds support for disjoint unions, blank node creation with RDFlib, and removes OwlReadySharedBlankNodeError when transfering constructs.

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

Thanks Jiba
Do you have any illustrations of the additional bnode functionality to share please?

[Jiba]

Hi,

You can now create blank node with RDFlib, however, you need to create the blank node with the new BNode() method of the graph object, as in the following example:


import rdflib
graph = default_world.as_rdflib_graph()

bn = graph.BNode()

with onto:
      graph.add((bn, rdflib.URIRef("http://www.w3.org/1999/02/22-rdf-syntax-ns#type"), rdflib.URIRef("http://www.w3.org/2002/07/owl#Class")))
