Sounds good.  Here an updated and polished one line description:

A R6RS and R7RS API for any database with a text query language that
returns rectangular results.

See https://github.com/Schemepersist/sdbi-design/blob/master/remit.txt
for the current version and an explanation of rectangular results.

I'll take it as a given we won't go out of our way to make life hard
for previous Scheme standard revisions etc.
