Different software license options are available for the standard scripts. The most common is the GNU GPL, but there are others like the MIT. We need to discuss which license we want to use for our standard scripts, meaning programs, macros etc. in SAS, R, Java or whatever. All should be able to benefit from the collaboration including Authorities, Companies, CROs and Academia.
The following Wiki should be used for License discussions.
GNU GPL V3
The “General Public License” is the most common used license for open source projects.
The GPL is very restrictive when it comes to commercial usage and modifications. When we want to use standard programs, it is very likely that the programs need modifications, e.g. when we need to use company styles, specific dataset adaptions or even special footnotes. We also want CROs to be able to use the standard scripts when they should program outputs for companies and companies being able to use those when outputs are produced for authorities. Is this a kind of commercial use? Our collaboration could be different from the general open source projects, as the covered topics are business driven.
When a project is started under GNU GPL V3, it could cause major problems or might even be impossible to migrate to a different license which is more open.
Someone needs to investigate whether and how we can use this license.
The “MIT” is a very open license. It seems that everything can be done with the “software”. So there seems to be no restrictions.
This means that people could take up collaborative work and “sell” this which is of course not an intention for our initiative. But how high is the risk, when the companies known of the work and available free scripts through the community? And wouldn’t it be a risk for adapting e.g. macros without publishing it to “sell” it when it is likely that the community implements later on features differently, so the finally user friendliest version is done by the community anyway?
When a project is started under MIT, the project can easily be migrated to another license, but the status from the migration always stays MIT.
Also here someone should investigate the risks and chances of this license.
Apply a license and disclaimer
To apply the license, a standard text (see external links for details) should be included in all scripts, e.g. programs and macros in the header). Furthermore links should / must be provided to the license details, e.g. the GNU GPL V3 webpage. Do not forget the disclaimer, as we do not guarantee that the scripts always work as expected. Even when we perform a validations, not all cases and situations can be checked, so there might be bugs or version dependencies (e.g. version 9.2 of an executing system might have a different behavior then a version 8).
The following text can be used for MIT:
