Loading ontology via owlready yields error

Question

I would like to use the ontology "dbnary" and I am using owlready When trying to load the ontology from the website, I get this error :

Maybe I am using the wrong library, is there a library to work with ontology in turtle format. I want to extract synonym of words via that library.

from owlready2 import *
onto_path.append(r"C:\Users\Em\Docu\tal\Substitution\fr_dbnary_ontolex\fr_dbnary_ontolex.ttl")
onto = get_ontology(r"C:\Users\Em\Docu\tal\Substitution\fr_dbnary_ontolex\fr_dbnary_ontolex.ttl")
onto.load()

#error 
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
~\Anaconda3\lib\site-packages\owlready2\driver.py in parse(self, f, format, delete_existing_triples, default_base)
    153               if not line.endswith("\n"): line = "%s\n" % line
--> 154               s,p,o = splitter.split(line[:-3], 2)
    155 

ValueError: not enough values to unpack (expected 3, got 1)

The above exception was the direct cause of the following exception:

Answer 1

From Owlready2's doc:

Owlready2 can:

• Import OWL 2.0 ontologies in NTriples, RDF/XML or OWL/XML format

Use RDFLib for parsing Turtle.
