Parser from OWL/XML TO RDF/XML problem

[Jesus]

I've used

 from owlready import *
 onto = get_ontology("file://C:\\Users\\ ... myPathTo.owl ...").load()
 onto.save(file=" ... name ...", format = "rdfxml")

but it gets errors when is executed such as

 "Ontology IRI does not ends with '.owl' as expected."

Hi,

Which version of Owlready are you using? This error was present in Owlready 1, but no longer exists in Owlready 2. I highly encourage you to switch to version 2, because it is much faster, has more functionalities and also better parsers.

Thanks for such a quick reply. But it still does not work, this crashes in some lines. For example with Protégé it works without problems, I don't know what differences there will be

Hi,

I need more information to investigate the problem. Can you give me the entire error message (including the traceback)? An example of code and/or ontology could help too.

Hi,

It's confidential and I can not share it.

---- the code is

from owlready2 import *

drm = get_ontology("file://C:\\Users\\...Path to ...\\file.owl").load()

and it fails.

---- the traceback is

Previously I get an error in line
...
...
...
KeyError: 'ontologyIRI'  

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

File "..... \PYTHON\lib\site-packages\owlready2\owlxml_2_ntriples.py", line 492, in parse
    raise OwlReadyOntologyParsingError("OWL/XML parsing error in file %s, line %s, column %s." % (getattr(f, "name", getattr(f, "url", "???")), parser.CurrentLineNumber, parser.CurrentColumnNumber)) from e
owlready2.base.OwlReadyOntologyParsingError: OWL/XML parsing error in file .....\file.owl, line 7, column 56.



I do not know what happens ...

best wishes

Hi,

It seems that your ontology is in OWL/XML format, and that the <Ontology> tag has no "ontologyIRI=" attribute. This attribute normally indicate the IRI of the ontology. Is it missing?
