Re: Survey for media-type evolution

Hi Pierre-Antoine,

Thanks for the effort!

I can confirm that Comunica (https://comunica.dev/) also gracefully handles your resources:
https://query.comunica.dev/#datasources=https%3A%2F%2Fperso.liris.cnrs.fr%2Fpierre-antoine.champin%2Findex.ttl&query=CONSTRUCT%20WHERE%20%7B%0A%20%20%3Fs%20%3Fp%20%3Fo.%0A%7D

Kind regards,
Ruben Taelman

A long standing question that we have to respond is whether we should change the media types of the formats, or keep them for the new versions of the format [2,3].
