Excuse me... BTW, is there a mailing list to discuss such design problems?

Moreover such a dbfs should allow rapid development of views over data
(with different permissions) by simply write the query in a file and
then open the file for reading the XML.

First of all... Thanks for your reply!
I hope we could continue this brainstorm... it was really useful for me.

I split my system into two - one to deal with the SQL and one that makes a
FS tree from columnated data. Though I abandoned dev on the tree because I
just ended up accessing the data through the Limbo pg module directly.
How was the data more outdated than when you used pg directly?
I ended up just adding the PGmodule to the app instead.
You used libpq to write such a PGmodule?
I worked with PostgreSQL for 6 year... I find it wonderfull, and I would use
it as the db backend for any opensource application I would write.

the pg protocol and saw it didn't map very well. I couldn't see what one

too)
- a data file (append only in the transaction, but not outside) where

On db ↔ fs conversions:

there's two things you could mean here: either the
relations between the data fields/types or the relations
between their values. SQL databases are interesting
because they don't do anything to keep the relations

just to be clear, i think webtop or web based approach is a backward
step (or at least a side step). the whole point of plan9 is to
represent everything as a namespace; in rangboom it means representing
distant filesystems in the native form, hence use of windows IFS and
FUSE for Linux and Mac.

filterfs: sythesize a filesystem from other fs and rc filters. could use
exportfs as a start. design in mind, no code yet. at one
point ehg mentioned such a thing at Labs.
sessionfs:

and error handling)
an rdbms interface will be messy; maybe just try to get a ODBC client
