Re: content negotiation isn't working

`text/turtle` is indeed the registered MIME/media type for Turtle syntax:
https://www.iana.org/assignments/media-types/text/turtle

Might want to handle both going forward though.

Cheers,
Benjamin

Cheers!

For the moment, I am happy to scrape the linked data description from
the RDFa.  Just thought it was worth mentioning that it didn't behave as
I had expected.

b.t.w. I think the generally-accepted MIME type for Turtle is
"text/turtle".  "application/x-turtle" fell out of favour a while ago,
as far as I am aware.

Best wishes!

Mark
