Incomplete license information

[stefan6419846]

The wheels apparently ship with patched templates from Django itself:

     adminsortable2/templates/adminsortable2/edit_inline/stacked-django-4.2.html          
     adminsortable2/templates/adminsortable2/edit_inline/stacked-django-5.0.html
     adminsortable2/templates/adminsortable2/edit_inline/tabular-django-4.2.html
adminsortable2/templates/adminsortable2/edit_inline/tabular-django-4.2.html.orig
     adminsortable2/templates/adminsortable2/edit_inline/tabular-django-5.0.html
adminsortable2/templates/adminsortable2/edit_inline/tabular-django-5.0.html.orig

I could not find any license details for these files (especially relevant on distribution, id est inside the PyPI wheels), although they are subject to the BSD-3-Clause license and have different copyrights compared to your own package code.

Interesting use case. The patched files are not part of this repository, they are generated during the build and publishing state. So what is the resulting license of a BSD-3 licensed file patched by an MIT licensed file?

What would you suggest as solution?

One could argue that the patches should be subject to the BSD-3-Clause license as well as they refer to BSD-3-Clause code and partially reproduce them. Other approaches might be possible, but I am not a lawyer and therefore I am limiting this to the basic approach.

I would recommend to either add a corresponding section to the django-admin-sortable2 license file or to each of the bundled files. (An alternative could be the ABOUT File Specification, although this might require adapting your MANIFEST file to include these files inside the distribution.) Something like this should work (here inside the template, I use some similar snippet inside some of my own code as well):
