Hi Thiemo, from the Creative Commons attribution license (v. 4.0):
If You Share the Licensed Material (including in modified form), You must: retain the following if it is supplied by the Licensor with the Licensed Material: identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);
I would point specifically to the words "retain" and "reasonable." Take a look at the following example:
- File on English Wikipedia:
- Username attributed on the Wikipedia page prior to move (blue link leading to genuine information):
- File after move to Commons:
- Username attributed on Commons after move, but before manual repair (redlink):
The photographer uploaded the file to English Wikipedia, and in so doing, defined the way he wanted to be attributed. In addition to his username, the method of attribution included a link to a page that has his username, and further information about himself, including links to blog and website.
After a move by this tool, that information is not retained. The blue link becomes a red link, which leads to a blank page inviting the reader to "create" it. It matters not to any reader who lacks intimate familiarity with the inner workings of wiki sites that there is some link between that blank page with the word "create" and some page on a different website which has the information they may have been seeking. To expect most users to get from the page they land on to the page originally linked as attribution would not be reasonable.
The solution to this problem, I think, is technically very simple: Simply have the tool insert the proper code in any relevant userpage links to retain the original link, as I did manually here.
