Die namiddag, op [frontend]:

What @mvuijlst and @defreek suggest is akin to unix file permissions w/ an owner.

Symbolic Notation   Octal Notation  English
----------          0000        no permissions
---x--x--x          0111        execute
--w--w--w-          0222        write
--wx-wx-wx          0333        write & execute
-r--r--r--          0444        read
-r-xr-xr-x          0555        read & execute
-rw-rw-rw-          0666        read & write
-rwxrwxrwx          0777        read, write, & execute

to have it resource oriented this would result in -crudcrudcrud (using symbolic notation)

Would this cover all needs?

Ja, ik kan daar hard om lachen, ik.
