RDF is the world's most outlandishly bloated way of expressing triples.
IBM did not adopt it for Watson, Google never adopted it, Facebook never
adopted it, Amazon never adopted it. Apple never adopted RDF, and they
trounced Nokia, who poured millions of euros into research on the Semantic
Web.</p><p>Even the W3C has backed off from using RDF by promoting RDFa,
whose only resemblance to RDF is in the three lettters R D F. Programmers
are rapidly migrating away from RDF to notations such as JSON, which is
basically LISP with curly braces.</p><p>At this late date, why would
anybody working on NLP adopt a notation that all the major web companies
abandoned or rejected?</p><p>John</p>
