In the search for an appropriate rubric to govern the sort of licenses which will be permissible for content hosted by FLCS I have discovered the Free Cultural Works definition which I believe suits our purpose nicely:
- Availability of source data: Where a final work has been obtained through the compilation or processing of a source file or multiple source files, all underlying source data should be available alongside the work itself under the same conditions. This can be the score of a musical composition, the models used in a 3D scene, the data of a scientific publication, the source code of a computer application, or any other such information.
- Use of a free format: For digital files, the format in which the work is made available should not be protected by patents, unless a world-wide, unlimited and irrevocable royalty-free grant is given to make use of the patented technology. While non-free formats may sometimes be used for practical reasons, a free format copy must be available for the work to be considered free.
- No technical restrictions: The work must be available in a form where no technical measures are used to limit the freedoms enumerated above.
- No other restrictions or limitations: The work itself must not be covered by legal restrictions (patents, contracts, etc.) or limitations (such as privacy rights) which would impede the freedoms enumerated above. A work may make use of existing legal exemptions to copyright (in order to cite copyrighted works), though only the portions of it which are unambiguously free constitute a free work.
I think that such licenses as are compatible with the above or works in the Public Domain will be the best candidates for hosting here at Free Library of Christian Scholarship.
