Key:image
There are serious problems with the use of this key in the database.
I recently started discussing the problems related to urls and File:filename.* that links to wikimedia_commons using the tag. See Talk:Key:image#Discourage_linking_to_commons_files_and_migrate_all_File:filename..2A_values_and_direct_urls_to_wikimedia_commons and tagging.
Algorithm 1
- image=File:* -> wikimedia_commons=File:*
- image=Category:* -> wikimedia_commons=Category:*
- image=https://commons.wikimedia.org/wiki/File:* -> wikimedia_commons=File:*
- image=https://commons.wikimedia.org/wiki/Category:* -> wikimedia_commons=Category:*
There are some image= tags that link to multiple images separated by ";". These will not be touched. (if a ; is found in the url this algorithm will skip it)
There are some elements like https://www.openstreetmap.org/node/674919702 that both link to a commons category with wikimedia_commons= and an additional image= that links to one of those images. I will not touch this as it would probably be best to introduce new tags commons_image and commons_category for this usecase like Yurik did in the tagging discussion.
There are some urls that link to a category and the media viewer. This is not always working (see [1]) but will not be touched by this edit as there have not been a discussion of this practice yet to my knowledge.
Algorithm 2
Based on suggestions by Yurik of separating the file and category references.
- image=File:* -> wikimedia_commons_file=File:*
- image=Category:* -> wikimedia_commons_category=Category:*
- image=https://commons.wikimedia.org/wiki/File:* -> wikimedia_commons_file=File:*
- image=https://commons.wikimedia.org/wiki/Category:* -> wikimedia_commons_category=Category:*
Note commons_file could also link to a video.
There are some image= tags that link to multiple images separated by ";". These will not be touched. (if a ; is found in the url this algorithm will skip it)
There are some elements like https://www.openstreetmap.org/node/674919702 that both link to a commons category with wikimedia_commons= and an additional image= that links to one of those images. These will be changed to commons_file and commons_category.
There are some urls that link to a category and the media viewer. This is not always working (see [2]) but will not be touched by this edit as there have not been a discussion of this practice yet to my knowledge.
Affected features
This edit will affect about 80,000 elements in the database. There are >80,000 image= tags with links to wikimedia commons where 50,000 of them is in Germany alone.
Execution
Changesets will be kept small ie. country size bbox maximum. For Germany there are ~50150 so there I will keep the bbox region sized.
I will use JOSM to make the changes using find/replace.
