Re: RDF Thrift : A binary format for RDF data

Thanks, Richard.
Yeah.
But it can be useful if you agree to mint the same MIME type as other people :-)
Would one use "application/rdf+thrift” or "application/rdf+x-thrift”, for example?
If I remember correctly, the x- usually indicates an unregistered type, but if the type is expected to get registered one day, then people often use the x-less one in anticipation, for future-proofing.

It is especially useful to use an agreed type if you want to consume other peoples’ services/data (or let them consume yours).
Of course I realise that is rather unusual in the SemWeb world, but it does happen ;-)

Best
Hugh
