Instinctively I dislike this intensely. It encourages bad practice by 
suggesting that identifiers for data sets should all be treated as 
ephemeral except the special case of the dcat:permanentIdentifier. Gah!

If you create a catalogue as an aggregate of other catalogues (like 
publicdata.eu) then you jolly well SHOULD use the original URIs from the 
original catalogue. If you don't/can't/won't, then at least have the 
decency to include owl:sameAs links.

As ever, I am aware that I take a purist view and that practicality can 
play a trump card - meaning that if there are cases where the reason for 
wanting permanentIdentifier is something a lot better than "we like the 
way we do it so we're going to use our lovely 
foo.aspx?sessionID=claptrap" URIs but we recognise that your well 
designed http://{domain}/{type}/{concept}/{reference} URI might have 
something going for it" then OK, I won't be intransigent - but I don't 
like it.

So, -1 from me, but I remain open to persuasion if the evidence is there.
