1. Introduction
|
||
|
|
|
||
|
|
The following is the README text for the LDraw Parts Library
|
||
|
|
licenced by the Creative Commons Attribution Licence 2.0 as
|
||
|
|
specified by the LDraw Contributor Agreement (CA). Parts which
|
||
|
|
fall under this agreement will contain the following line in
|
||
|
|
their headers.
|
||
|
|
|
||
|
|
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt

However this text is not a license! It is simply a handy reference
|
||
|
|
for understanding the Legal Code (the full license), which can be
|
||
|
|
found in the CAlicense.txt file - it is a human-readable expression
|
||
|
|
of some key terms. Think of it as the user-friendly interface to
|
||
|
|
the Legal Code beneath. This text itself has no legal value and its
|
||
|
|
contents do not appear in the actual licence. For a deeper insight

2. Rights
|
||
|
|
|
||
|
|
You are free:
|
||
|
|
|
||
|
|
* to copy, distribute, display, and use the CA approved LDraw
|
||
|
|
Parts Library
|
||
|
|
* to make derivative works
|
||
|
|
* to make commercial use of the CA approved LDraw Parts Library
|
||
|
|
|
||
|
|
Under the following conditions:
|
||
|
|
|
||
|
|
3. Attribution.
|
||
|
|
|
||
|
|
You must give the original author credit.
|
||
|
|
|
||
|
|
* For any reuse or distribution, you must make clear to others
|
||
|
|
the licence terms of this library.
|
||

|
||
|
|
|
||
|
|
The LDraw Steering Committee (SteerCo) also holds an attribution
|
||
|
|
to 'The LDraw Parts Library' in such Derivative Works to be sufficient
|
||
|
|
in lieu of a full list of authors.

Your fair use and other rights are in no way affected by the above.
|
||
|
|
|
||
|
|
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 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.
