[galaxy-dev] Licensing Galaxy workflows; are they software or documents?

Hello all, A philosophical question - for my Galaxy tools and wrappers, I have been using open source software (OSS) licences, e.g. the MIT license, or GPL. For licensing my Galaxy workflows, should I also treat them as software and do the same, or as a protocol document and go for something like one of the Creative Commons licenses? e.g. CC BY, or CC BY-SA Thanks, Peter
