There is one aspect that I am a little worried about and it deals with
unofficial files... we can make it clear what a model file is (references to
parts only) but then we have the problem that it is considered good practise to
include unofficial files in a model file to ensure it remains working. This
would not be covered by such a limited definition.
Perhaps something like:
"LDraw.org is the sole entity responsible for enforcement of the Parts Library
copyrights. LDraw.org does not consider rendered images or LDraw model files [1]
to be derivative works of the Parts Library. Any MPD file containing Official
parts from the Parts Library is considered a derivative work. As a rule of thumb
if it includes any element of the Parts Library it is a derivative work.
[1] A model file is defined as a file which contains only type 1 [2] references
to part files. There are limited exceptions such as the inclusion of unofficial
parts (but not official ones) and the inclusion of primitives written by the
author. If in doubt please contact LDraw.org for more information.
[2] A type 1 reference is a line representing an LDraw commands of the form:
1 {col} {x} {y} {z} {R11} {R12} {R13} ... {R33} [FILENAME]"
