That's where I come in.

I think that, eventually, we should have some loadable Scheme modules that
provide convenient ways to specify database servers and schemas. For the
time being, however, I don't see any reason not to stick to using some sort
of external helper programs for actually accessing the database, as long as
we can get the UI and basic Scheme API nailed down.

The current component library isn't a file chooser. It's some sort of weird
file-chooser database-client hybrid thing. It's a bit like a file chooser
that's pretending to be a database client, and being neither one thing nor
the other, it doesn't really work terribly well.

Totally agree. Could we implement this by asking the backend to take care of
where the symbols come from, and merge them with the database info before
presenting them to gschem? Or is this the wrong way? Is it better to place
a symbol, then invoke a special "select part" command? My worry is that the
latter option would make it easier to end up with a resistor which thinks
it's an op-amp.
The commercial tools I've used which implement such a parts database have used
the former option -- OrCAD Capture CIS being the main example -- of
generating heavy symbols by adding database info onto a small collection of
light symbols. But is this the best option for us?

Not boring at all. Thanks for your input.
