Re: [dotNetRDF-Support] skos/rdf

[Rob V. <rv...@do...>]

dotNetRDF provides minimal control over how the RDF/XML is generated, as you
have noticed RDF/XML can serialise the same graph multiple ways.  Getting
serialisation correct is far more important to us than any concerns about
readability.  RDF/XML was never designed as a readable format and should not
be treated as such.

You can try tweaking the CompressionLevel property of the RdfXmlWriter to a
higher value (10 is highest) but this will likely make little difference to
the output for the graph you have shown.

As you point out the triples are the same so the serialisation is
irrelevant.  My advice is that whatever RDF tools you are using is to ignore
the serialisation and only worry about the triples.
