[protege-discussion] Export ontology from Protege server

[Jie Zheng]

Hi,

I am working with WebProtege which both Protege server and Protege rich 
client is Protege 3.4.6. I used Desktop protege to export the ontology 
from the server using "Export to Format' XML. I got error message when I 
open the exported ontology using both Protege 3.4.6 and Protege 4.1.

The error message got using Protege 3.4.6:
"Errors found performing operation.

1. An error occurred at parsing the OWL ontology

     http://purl.obolibrary.org/obo/opl.owl

     at line 2045 and column 737.
     Jena parse error message: XML document structures must start and 
end within the same entity.
     Exception class org.xml.sax.SAXParseException.  Message: XML 
document structures must start and end within the same entity.

See console and log for more details."

The error message got using Protege 4.1:
"Export ontology using Protege, export format as XML, when open using 
Protege 4.1 got following error

org.xml.sax.SAXParseException: XML document structures must start and 
end within the same entity.

I attached the exported owl file (opl_inferred_export.owl) and the 
original file stored in the Protege server (opl_inferred_server.owl).

Any idea of why it happen? Is it a bug of protege or did I do something 
wrong?

Thanks,

Jie
