OK, I understand what you intend (but didn't know - or forgot - you
planned to do so), but what do you expect those DOIs to land on?
Currently we expect the DOIs for the simulation to resolve to the
metafor page for the simulation (but see below *)
We currently have no logical CIM document which makes sense for landing
on a centre or a model.... and I'm not sure it makes real sense either:
academia doesn't have a DOI for normal publication aggregatoins - apart
from those which are published as deliberate anthologies ... when would
one publish these aggregations? At the end of CMIP5, at the close off
date for the IPCC ...??? How would we deal with these in the q.c.
sense? We'd end up with a new level of versioning for the centre and the
model ... (and only wrt to their use, not them themselves).

* Yes, and we'll have to increment those documents version to conform
with any changes to the realm datasets, even if they themselves don't
change.
This nicely contradicts something I was saying at the sprint: that we
could do the associations with a query. I should have known better. The
registry world deals with these sorts of asociatoins as first class
objects in their own right. So, eg, we should have:
s: a simulatoin description (v1)
d1, and d2: two realm descriptoins (v1)
a1: the association from s to d1 and d2 (at v1)
The citation will need to point to a1, not s, and be rendered
accordingly (one doesn't render a1, one renders s with the associations
denoted in a1).
If new versions of data are released, then even if s doesn't change, a
new association group can be created, and a new doi to point at that.
I don't think the CIM (currently) handles this gracefully. It will
within a week or so :-) (It would have had we really gone down the OGC
route properly where this stuff has already been thought through in the
context of ebRIM).
Hopefully that'll handle these issues.
Cheers
Bryan
