4. Enforcements
|
|
|
|
The single copyright holders are the sole entity responsible for
|
|
enforcements of their copyrights. For purposes of enforcement
|
|
LDraw.org considers the following good rules of thumb to determine
|
|
if a new file is not a Derivative Work. Anything else should be
|
|
considered a Derivative work and an attribution would be required.
|
|
If in doubt, contact the current LDraw SteerCo.
|
|
|
|
What is not considered a Derivative work?
|
|
|
|
* Rendered images generated from the LDraw library. Rendering here
|
|
covers any conversion of a 3D model file into a 2D image.
|
|
|
|
* Model files containing references only (the source code for the
|
|
part may NOT be included in any form) to parts in the official
|
|
LDraw Parts Library at the time of their creation. Part files
|
|
which are marked as unofficial at the time of creation may be
|
|
included in full in the model file. If the sole or main purpose (as
|
|
determined by the LDraw SteerCo in consultation with the potentially
|
|
offending author and the LDraw community at large) of the model file
|
|
is to include large numbers of unofficial parts then it WILL be
|
|
considered a derivative work.
|
|
|
|
* Alternative libraries of parts which LDraw.org does not own or
|
|
enforce the copyright. If some or more of the parts in the library
|
|
are converted from the LDraw Parts Library then they must be
|
|
considered a Derivative Work. |
