I understand that it is recommendable to treat Filesystem resources
in a uniform way, managed i.e. by a Jigsaw Webserver. 
I maybe to naive, but a direct alternative to a CGI accessible 
RDBMS is JDBC. If you don't rely heavily on HTML for other reasons, let
an JDBC Applet do the work in your browser. This shortcuts HTTP.

This makes the Create Methods to something like Factory Methods,
decoupling the Creation  API from the concrete Creation.
The implementation of the creation process is adaptable to
individual issues.
This I find particularly attractive in an open environment, where
the resource to be built i.e. doesn't come from the local file system,
but from a remote system transferred by something like ORB's.
