I think proper relationships are probably best though one can abuse
key/values for this :)

The main thing missing (at least from linked data perspective --
correct me if i am wrong Richard!) is the ability to add more info to
the link -- i.e. want not just to link but to say there these are
linked and have 100k triples pointing between them. Adding additional
metadata to links is reasonably straightforward but does require a
change to the core model and hence a migration. If someone wants to
jump in and try this they'll get full support and guidance from the
devs :)

In the mean time I'm going to try adding package relationship editing
to the proof of concept ckan javascript library/editor i'm working on:

I think you should start speccing one now even before we reach final
resolution ;)
