Hello,
I have two problems with loading ontologies and importing ontologies. 1、The first problem When importing ontology, how can I only import the instance of the ontology , (the ontology and the importing ontology have the same Classes ) 2、The second problem path = 'file://yang_v2-union.owl' unionOnto = get_ontology(path).load() When I use the codes as above to load the ontology which has importing other two ontologies (that is the owl file has the following statements: 'owl:imports rdf:resource=....'),I will meet the following errors(fstarting from 'Traceback'. I can not solve the problem. Please help me! Thank you!

How can I solve the baove two problems? Many thanks. Shirley |

Hello,
For the first problem, do you mean that you want to load only the ontology, but not the other ontologies it imports? For the second problem, the problem is that the imported ontology is not available online (the URL does not respond). In this case, if you want to work with local copies, you should put all OWL file in a given directory, and add this directory to the list onto_path, for example: onto_path.append("/path/to/directory/with/owl/files") Jiba |
