Do you notice that this is a primarily a TEXT!!!! system. Sure the
metadata will go into Oracle nicely, but if what you care about are the
articles, it sure sounds plausible to me that one would use a storage
system optimized for the articles, and then shoehorn in the metadata,
rather than use an RDBMS and shoehorn in the corpus.

Oh and for what it's worth, I have plenty of anecdotal information that
bibliographic metadata was a very hard problem for the relational model.
It may have been solved in the last few years, but it was still a
storage-eating performance killer ten years after the RM was the 'best
practice' for 'widgets in warehouses.'

Publishing/documents. I agree, Nature should maintain their subscriber
list in Oracle. That's not where the articles belong.
