well, use the usual interface:

stat
creat
lockf
open
write
read
close
truncate
unlink
opendir
readdir
closedir
rename
sendfile
utime
readlink

I don't get what good it would do to use some extra interface with
different functions, given that all possible basic actions are already
covered... (although transactions would be nice to have ;))

What do you mean by that?

You mean like in a relational database? That's very unflexible and a bad
idea on a filesystem. There is a reason relational databases are only
used properly in well-defined and limited-size big-design-up-front
projects.

And good relational databases are not even stored in files, but directly
onto the raw partition.

It really depends on what you want to do with it, but of course you can
store each field into a file of it's own. The question is if you need
that kind of fine granularity...
