The Creative Commons licenses regulate in detail, with pre-build modules, what is allowed by using the selected license and what is not allowed. Such modules can not fulfil all the variety of needs of all projects, and need specific additions or exceptions in individual cases.
CC+ is an special version of Creative Commons, which is intended for possible additions or exceptions to one of the existing standard CC licenses. The default license for all topos and the accompanying texts on RockTopo.org is the Creative Commons CC-BY-NC-SA 3.0/4.0, This standard license is complemented with the SLA license: CC+ = CC-BY-NC-SA 3.0/4.0 + SLA
Other content on RockTopo.org, like photos, videos, can be released under a different CC license, so our own wallpapers are released under the CC-BY-NC-ND 3.0 license.
