Kjetil,

As a first step to reaching common ground, would you say the following 
is identical to the above:

curl -iH "Accept: text/turtle" 
'http://data.lenka.no/fragments?subject=http://data.lenka.no/geo/inndeling/06/0627'
HTTP/1.1 200 OK

I see the following metadata, in TURTLE notation:

1. Hydra Template
2. VoiD.

So far so good?
