GeoMajas Provenance Review
To establish a reasonable comfort level that projects going through incubation do not have improperly contributed code, and that the code is all under the project license.
A code provenance review is desirable because it reduces the risk of the foundation, project developers or software users becoming involved in a legal action or having their use of the software disrupted by sudden removal of improperly contributed code. In particular, many enterprises will not build on open source software projects without some degree of assurance that care is being taken to avoid improper contributions.
It is not the goal to be able to prove that every source file, and every contribution to those files, was contributed properly. The onus is not on us to prove there are no problems. However we want to ensure we do not release code with provenance issues that we could have identified and corrected with a reasonable effort.
External components "in source tree" for the project
Code Copyright Review
- The original code was developed by DFC nv.
- The IP was bought by Geosparc nv from DFC nv on 01 Jan 2009.
- Any changes since code is owned by Geosparc nv are either by covered by a CLA (Contributer's License Agreement) or an employment contract, transferring copyright to Geosparc nv.
General, see contributors guide :
- All Java files contain a copyright statement which is checked as part of the build.
- All authors are required to add their name in the list of authors at the top of the files.
The objective here is to visit every source file, and identify possible issues, and work to "regularize" things.
The result of the provenance review is two fold. First, there is clarification and "fixes" done during the review. For instance, adding missing copyright notices, or factoring out external libraries. The second is a review report with a fairly detailed list of outstanding issues, ambiguities and information of note.
Action points resulting from the review:
- All resource directories needs a "LICENSE.txt" file indicating where the files came from when not original work of the project (original work includes stuff like screen shots or specially created graphics). All resources for which the source and/or license is unclear need to be removed or replaced by data for which the license is acceptable (DONE).
- The back-end and all plug-ins need to maintain a list with copyright/license details (DONE).
- These details need to be logged when starting the application (DONE).
- A command needs to be created to get this information from the system (DONE).
- Faces need to display this copyright/license information in an about box or similar. This needs to be a requirement for graduating a face (DONE).
- Contributors guide needs to be adjusted to mention that copyright/license info needs to be maintained on the back-end and plug-ins (DONE).
It is sufficient to refer to a single copy of the license agreement for the project, but each file should include an indication of what the license is, and the location of the full license document.
