We discourage the use of large RDF/XML dump files in the context of GoodRelations, since they are a perfect entry for Denial-of-Service attacks. Also, properly deploying RDF/XML resources on production systems is often difficult in an enterprise context. Even supporting the rdf/xml media type can pose a challenge when there is fine-grained access control on production systems.
