Artisan Software Licence
The Artisan Software Licence is an open source software licence created by Alexander Nicholi in response to a Twitter conversation started by Wolf Tivy about monastic software development. Wolf identified that a good way to enshrine this is through a new sort of software licence that ensures sharing of source code as it is, but gives the authors discretion through copyright who is allowed to distribute derivative works. In principle it is very similar to the Creative Commons Attribution–No Derivatives licence for creative and cultural works.
In 2022, the ASL was updated to version 1.1 to comply with the Open Source Definition as defined by the Open Source Initiative. It includes a clause explicitly permitting the inclusion of discrete "patch files" as the form taken by modifications to ASL-licenced source code. Plain text, rich text, Unicode and ASCII-only versions were differentiated for both versions of the ASL.
