I am a novice to the Jena API. I would like to read an ontology as depicted
in the code below:
The problem is the following:
1. the ontology is not hosted on the web currently and have a local copy.
I added the alt entry as depicted in the code below to address this.
This is A.owl in the below code.
2. Ontology "A" has a direct import to Ontology "B". I also added the alt
entry for that.
* OntModelSpec spec = OntModelSpec.OWL_DL_MEM;*
* spec.getDocumentManager().addAltEntry("www.example.com/A.owl",*
* "file:D:/ontology/A.owl");*
* spec.getDocumentManager().addAltEntry("www.example.com/B.owl",
"file:D:/ontology/B.owl");*
This should be the full URI, *exactly* as it appears in the source code
that you are reading. So I would have expected:
.addAltEntry( "http://www.example.com/B.owl";,
"file:D:/ontology/B.owl");
assuming that you have in your source code:
<>
a owl:Ontology ;
owl:imports "http://www.example.com/B.owl"; .
By the way, I don't use Windows, but I think you'll find that the
alternate file URL will be more robust if you make it an absolute URL,
not relative. So:
"file://D:/ontology/B.owl"
