Hi Dave,
I agree there is technically no problem with either representations.
However we need to document in our specification (in ABBREV xml) with
examples which one it will be. Currently it could be either depending on
which server at runtime. There could be non-Jena, or simple XML parsers
which could not parse the other output. We just want to consistentently
specify the first format (which is valid).
I tried the RDFSyntax.sectionReification() with no improvement - still get
different outputs for URL changes. Maybe I am doing this wrong?
RDFWriter abbrevWriter = model.getWriter("RDF/XML-ABBREV");
abbrevWriter.setProperty("blockRules", new
Resource[]{RDFSyntax.sectionReification});
//abbrevWriter.setProperty("prettyTypes", new Resource[]{DCTerms.Agent});
model.write(System.out, "RDF/XML-ABBREV", someBase);
Regarding 'rdf:Id' - since Statement.createReifiedstatement() generates
either format depending on URL, we are thinking of not using it but rather
somehow attaching 'rdf:Id' to the statement. Doing this will allow us to
generate a top level rdf:Description about this rdf:Id (like example 20 in
http://www.w3.org/TR/rdf-primer/#reification).
I have opened https://issues.apache.org/jira/browse/JENA-183 to track this
further.
Thank you for your time,
Regards,
Srimanth.
