As an independent web developer I personally find it easier to work with
RDF triples than with JSON.  One single advantage of JSON imho is that it
does not require a parser when working with JS.  But adding a parser is one
like of code for me, so not a huge overhead.  But I suppose everyone will
have their own preferences.  So thanks for putting this together!
