# Build a Commons Extension
- It gets the url of a wikipedia file
- It checks if the licence allows it to be moved
- It creates the file on Commons, with history etc, displaying correctly who uploaded the file
- Details: In the file history, there should be one entry that says that the file was moved and who moved it and another entry saying that the template was changed to the current one
- TODO build a mockup
# Add a link to wikimedia file page
- The link "Move to Commons" should be a tab next to version history (and will probably be bundled under the "More" tab
- The link is only there, if the licence may allow the moving of a file, if not, it is greyed out (with the explanation in a tooltip)
- The link is only visible with the people who have the rights (TODO WHO?)
# Allow the undoing of a file move
- users with rollback rights might undo a file move
- This will result in the deletion of the file on commons and the reinstantiation of the file on Wikipedia (files may alway be reinstantiated by people with admin rights)
