COSPA 1.0 (Compatibility Open Source Protection Agreement)

0. Definitions

0.1. Reference to COSPA: Defined on a per-project basis. If one or more files within a project hold the COSPA license, the project as a whole shall be deemed to "reference COSPA".

0.2. Holding COSPA: Defined on a per-file basis. If a file holds COSPA, it is equivalent to stating that the file is subject to COSPA.

0.3. External License: Any license other than COSPA that is held by a file due to its origin or inclusion. This excludes licenses actively chosen by the project author for their own original work within the project.

0.4. Automatic Application: Defined on a per-project basis. If a project references COSPA, then after all possible licensing effects have taken place (with any External License taking precedence over COSPA), COSPA shall automatically apply to any file within that project that does not hold an External License. Such files shall be deemed to hold COSPA and are prohibited from actively adopting any license other than COSPA.
