Missing license statement

[stweil]

The project includes many files with a license header, but I did not find any information on the license used by the whole project. Is it GPL2 / GPL2+ / GPL3 / GPL3+?

I suggest to add a license file in the standard form which is recognized by GitHub and other tools.

@albig What is the standard procedure for licensing of TYPO3 extensions?

[albig]

That's not only related to TYPO3. The LICENCE.txt file is missing. See https://help.github.com/articles/licensing-a-repository/. We should put the same as in Kitodo.Presentation.

According to https://typo3.org/index.php?id=782, GPL2+ seems to be the right choice. GPL3 / GPL3+ are compatible to GPL2+, so I think that using them would also be possible.

Obviously TYPO3 documentation requires a different license, see https://forge.typo3.org/issues/46163.

[stweil]

I think that using the same license (GPL3) as for Kitodo.Presentation would be reasonable.

By the way: The trigger for this issue was https://www.wikidata.org/wiki/Q47007505 (which already suggests that GPL3 is used).

Thanks a lot.
