I'm not sure I understand that statement. My understanding is that there
will will be DOIs that point to simulations (which are run by models at
institutes on platforms in conformance to experiments). Those documents
will point to mulitiple realm datasets.
We need to deal with what happens with changing versions of data, but
that's a slightly indpendent issue: but certainly, if the simulation
points to *different* versions, it's a different simulation instance, and
itself has a version increment.

Further, we point DOI's to particular metafor simulation documents,
which need to be fixed* once the DOI points to them, and they need to
point to fixed versions of data.

So, the only change to a fixed* metafor document should be that it is
allowed to be have a DOI added to it (the DOI that points to it). Once
that is done, the document will propagate into the ESGF and everyone
lives happily ever after.
*fixed to indicate that it is *really* fixed, once a DOI is assigned to
it. The only wee problem is that we need to assign the DOI to a metafor
document version which is one higher than the latest - ie to the one
with the DOI in it.
