Deep below DatasetAccessor.putModel(), I get the following error:
com.hp.hpl.jena.shared.BadURIException: Only well-formed absolute
URIrefs can be included in RDF/XML output: <> Code:
57/REQUIRED_COMPONENT_MISSING in SCHEME: A component that is required by
the scheme is missing.
Placing a breakpoint where the exception is thrown reveals that
BaseXMLWrite.checkURI has been given an empty String.
So, I looked for empty URI strings in the Model being written, at
least as represented in Eclipse's toString() output. I'm not sure what
format(s) the following is in, but I see empty subjects in some triples,
all of which are associated with the ontology imports. (It has been
edited to remove proprietary info):
I can't tell without more information, ideally something that can be run
and also a stacktrace.
but it's to do with the model passed into putModel so try writing the
model as RDF/XML and as N-triples.
This:
[, http://www.w3.org/2002/07/owl#imports, http://anchor/OntS]
looks like the subject is the URI string ""
