However, I've been thinking about how to create a supplementary license for the product identity stuff, similar to the way the D20 STL defined under which circumstances you could use WotC trademarks to indicate compatibility with their products. I want:
- to allow people to use certain parts of my product identity in their own products, so long as they give proper attribution;
- to allow people to make comparisons or references to or express compatibility with Liber Zero in their own products without having to go through semantic gymnastics;
- to protect the text of a complete, final document, particularly if I plan on publishing such a document commercially.
I'll have to work on exact wording of the attribution clause and decide what other material beyond the basics should go into the SRD. If anyone has any comments about what they think should be included, or personal experiences with licensing their own game materials, I'd appreciate it.
