Hi Max, > However shouldn’t it be “text/x-org”, not just “text/org”? (I am against > “application/*” variants since it is a text based format). As per the de-facto mime type for Org is `text/org'. Why not `text/x-org'? Among other reasons, the `x-' prefix is depreciated as of RFC 6648 (2012). Existing MIME type databases that use `text/x-org' should be updated to use `text/org'. We are missing IETF MIME type registration, but I hope to get to that at some point. In the mean time the realistic options are `text/org' and `application/vnd.emacs.org' — and I think we’ll all agree that the former is vastly preferable.
