Say, has anyone considered LDraw DAT file certification for clones? (I don't
mean clone brands of LEGO bricks, I mean clone software of LDraw/LEdit/etc.)
Some random thoughts...
ldraw.org could maintain the official definition of the LDraw DAT file format
and certify (or allow clone authors to self-certify their) software packages
which import or export LDraw DAT files.
The definition could say things like: a program which writes LDraw DAT files
-must- output LDU coordinates as decimal integers or IEEE floating-point
numbers, -may- output these numbers to high precision, but -should- round
them to at most 2 significant digits past the decimal point.
And there could be a few sample files for regression testing and that sort
of thing.
This way, packages like MLCad and LeoCAD (and clones like LDLite) would have
some sort of official working definition of the file format, and inasmuch as
certification doesn't mean a whole lot from the "Hey, wow, it's certified!"
wowie zowiee point of view, I think may encourage more careful attention to
details and conventions.
