Having read through this thread, I've seen a lot of good points made.
However, it also appears that people haven't really fully thought about the
implications of meta-commands.
It's very important to realize that meta-commands are presented as generic
.dat comments. Some of the meta-commands that I have seen listed in this
thread don't reflect careful consideration of this fact. (And, while it may
not be in this thread, the "0 FILE" MPD meta-command is arguably the worst
offender.) When you choose a meta-command, it should be something that is
incredibly unlikely to be entered as a standard comment by someone.
For better or worse, we're now stuck with the orginal LDraw meta-commands,
and effectively stuck with the meta-commands that are already in use (for
BFC, MPD, etc). But, if we're going to try to decide how define good
behavior for future meta-commands, I think we should come up with something
that guarantees that legitimate comments aren't mistaken for meta-commands.

I've been tossing around the concepts of an LDraw file format standards body with Tim and others, and IMHO the weakest link in the LDraw file format is that comments and meta-commands use the same record type.

| Hi All, As long as we're updating documentation, I'd like to create a list of the known meta-commands. The process for defining new meta-commands is completely unregulated, which is fine, but as a newcomer to LDRAW compatible CAD tools development, (...) (21 years ago, 14-Mar-03, to lugnet.cad.dev)
