Media Type for GRLC

[kad-beekw]

Thanks for working on an standardized approach for exposing SPARQL query metadata!

In TriplyDB we expose all our saved queries as GRLC. We are already exposing some properties, and are planning to add more of them over time.

When a client wants to retrieve the GRLC version of a query, they currently issue an HTTP request with the text/plain Media Type in the Accept header.

This is a reasonable temporary solution, but for the long term it would be better to have a specific Media Type format, maybe application/grlc (or application/sparql-query+grlc). Such Media Types can be proposed at IANA, an Internet standardization organization (link).
