We used a similar approach. Our Preservation Department records a
bunch of data in an RDB at scanning time and exports text files that
we use to generate digital collections. Some of this was outlined as
part of a talk at DLF in the fall. Slides and handouts are at:

The handouts may be more useful, as the slides are mostly pictures
that I'd talk about. If you DON'T use the slideshow, you'll see the
outline slides that were hidden. Anyhow, the METS to GSAF mapping is
pretty natural. I can share the XSLT we use, though it is fairly
custom to our local needs.

Will all of your collections be using the same metadata set? If not,
you'll want to allow for that in your METS construction stream and in
the METS to GSAF transformation. Should be easy enough to check the
dmdSec attributes and invoke the correct template (assuming XSLT).
