LDRAW.ORG PARTS LIBRARY AGREEMENT: CAreadme.txt

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 please visit: http://creativecommons.org/licenses/by/2.0/

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.
   * Any of these conditions can be waived if you get permission from the copyright
     holder.

The 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.

   * Alternate 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.
