Identifier Domains Registry (aka. IDR)

Problem
Imagine: You have created an object or a set of objects (a kit¼), and when you or somebody else deploys it/them, a conflict arises. Somebody else has used the same name for a class, and the project won't link, or give errors when some code in a bundle is loaded. Someone has to give in, but who? And even so, there is bound to be some sorrow for some developer(s) and/or user(s). Maybe some code that is already in established use has to be adapted as a result. Suppose you're called Ervin Oldfield, so you're using the prefix EO, and suddenly some software company comes trampling all over you...

``Solution''
We're in the objects business, folks! Here is where you should turn to to make sure such a conflict will never happen to your code (``I want to use such-and-such a prefix, is it still free, and if so, would you register it for my exclusive use?''), or at least it will then be less likely, if everyone participates. I volunteer to maintain this at least for a while.
This is not a real solution to this problem, of course, just a workaround, painting over the rust. But it should make a difference. (A real solution would be an entirely different programming environment, I suppose.)
Warning: This is just a means to coordinate efforts, without authority, and it relies on the cooperation of the participants. If a conflict arises about established code, please try to resolve it amongst yourselves.

Guidelines
· Important: Don't use a digit as the first character after the prefix, because this is an escape mechanism whenever conflicts arise.
· It is assumed that if you have registered a prefix, then you may also use it with any number of underscores in front of it. Right?

Good style
· Occupy as few slots as is feasible (which should really be only one); use additional prefixes after the initial prefix to create subdomains (e.g., NeXT should have used NXDB, NXIB, NXIX, NXWM, NX3D, ¼).
· Individuals and small companies should use at least 3 letters, larger companies may use 2 (or more); conflicts will be resolved by appending digits to the desired prefix.
· Your prefix does not need to be all capitals, it's perfectly OK to use something more descriptive.
· If you've been using a prefix that doesn't follow these good-style guidelines, and it is not feasible to adapt things, then maybe that can't be helped. But do explain carefully why your claim should be accepted anyway.

How to register
· Send your requests to Raf_Schietekat (aliases explained below). Please use the subject ``Identifier Domains Registry''.
· Motivate the requested prefix (e.g., by stating your full name with any middle initial).
· This is also for established code that you know of, NEXTSTEP related or not.
