Re: Related to Issue-46

Hi Phil,

Very sorry for this. To be honest I was not aware of the presence of this
text on persid.org but, as you would expect, I strongly disagree with it
too. We should definitely remove the link, I would not mind keeping the
word "persistent" but that one can go too.

Just to give a bit more context there is some agreement at DANS that URNs
are not enough and that you need some dereferencing service to go with it.
So far the focus is set on http://persistent-identifier.nl/ for this but
unless you know it. We are moving into exposing all the meta-data we have
about preserved entities as Linked Open Data. I hope this move will be
joined by a switch towards using URIs as persistent identifiers but it
takes time to change things...
