Hi!
Thank you so much for this awesome API bringing ontology work to the modern world in Python :)
I have an ontology (RDF/XML) built in Protege to the effect of:
----
Classes:
Thing
Ingredient
Kale <--- subClassOf: hasTaste some Bitter . EquivalentTo: {kale}
Taste
Bitter <--- EquivalentTo: {bitter}
Individuals:
kale
bitter
Object Properties:
hasTaste
----------
Notice that I've closed/reified the Kale and Bitter classes to include exactly 1 individual each. When I run the following code:
from owlready2 import *
world = World()
onto = world.get_ontology('.../my/ontology/file.owl')
print(onto.Kale.instances()) # []
sync_reasoner(world)
print(onto.Kale.instances()) # [onto.kale] GOOD!
print(onto.hasTaste[onto.kale]) # [] BAD; Expected: [onto.bitter]
Any ideas how to make this work? I've tried wrapping it in with onto: ... But that hasn't worked either.
Thanks in advance!
