you are not the creator of the SRD, so you cannot enter into a different agreement, WotC however could publish the SRD under the OGL as well
If there is something in the CC which you can publish under the CC, the terms of the CC say you can publish it into another license provided you follow their attribution requirements.
The OGL (not the SRD - the OGL) doesn't have any bar, as far as I know, in publishing your CC content into the Open Game License. You do not need to be the creator of the material to use the OGL, you just have to " have sufficient rights to grant the rights conveyed by this License." Which, as far as I can tell, you do have. The CC explicitly says you can put it into a different license - even a more restrictive license. So you have the rights to convey into the OGL as far as I can tell.
Tell me where I am going wrong here? The steps are:
1. WOTC puts content into the CC.
2. You use that CC content to create a new CC contribution.
3. Your use of the CC to do that, comes with explicit permission under the CC to put your CC contribution into another license (even a more restrictive one like the OGL), provided you follow their attribution requirements.
4. You then put that CC contribution into the OGL.
5. The OGL does not require that you be the copyright owner of material you put into the OGL. It says it needs to be your original content OR "You have sufficient rights to grant the rights conveyed by this License." Which, under the terms of the CC, you do.
6. The WOTC content put into the CC, by means of your new contribution under the CC and the OGL, is now in the OGL for use by others.
What part of this is flawed?
