What is the problem you want to solve?
Normal way of uploading files using Special:Upload lacks of machine-readable metadata field. (i.e. Template:Information must be manually added and most of user are unaware of this template)
Users are confused on choosing the licenses and hence numerous images are wrongly licensed (e.g. fairuse image tagged as GFDL). This is mostly due to the confusing and text-heavy UI when choosing the licenses.
Which users would benefit? (editors, admins, Commons users, Wikipedia users, etc.)
Those who care about having correct machine-readable metadata in the images.
How is this problem being handled now?
Many wikis have their file uploading feature disabled and were redirected to Commons instead.
But similar to the case on local wikis, by redirecting uploading process to Commons, I observed that the users still upload fair-use image to Commons since they are not aware about file licensing stuffs and their purpose is merely to upload image, i.e. they will choose whatever license options available to enable them upload their image for usage in the article.
In en.wiki, "FileUploadWizard" has been created to insert Template:Information to the image and hence there are machine-readable metadata.
But to the other wikis where JS developers are lacking, nothing can be done since the localization has been hard-coded in the JS codes. Moreover, the UI has not improved since it is heavily text-based (and as a result, looks like a Terms & Conditions page)
I'm not aware about other wikis, but in id.wiki, localization effort of "FileUploadWizard" has been started but stalled due to the large effort needed in improving the UI.
What are the proposed solutions? (if there are any ideas)
Enable commons:Special:UploadWizard in local wikis, enhancing its features to adapt with local wiki rules, including the fair-use licenses.
Indonesian Wikipedia community has proposed this, but nothing has been done yet since this Phabricator task was not supported by the developers there. T88918: Enable Extension:UploadWizard on id.wikipedia
