I don't understand this comment.

The data attached to a key is arbitrary.  You could store a list of
stuff there if you want.

Christopher> Gnome.Open.2 -> "php -cgi < $this > $1"
Christopher> Gnome.Open.3 -> "netscape $this"

I don't understand this either.  Why would you want 3 ways to open a
file?  Remember, you can always load the file into any program you
want.  This is just setting the defaults for programs that want to
know how to open the file without popping up some unfriendly dialog.

This should be hidden in the program that is used to actually launch
the program.  The actual edit request should happen via CORBA.

Metadata processing works in phases.  You can have metadata attached
directly to a file, to a regular expression which matches files, or to
a file's type.  There are also various ways of determining a file's
type.

I don't understand this question.
