BUB2 tool helps librarians upload books in Public Domain from public libraries such as Google Books, Panjab Digital Library, and Trove Digital Library to Internet Archive. The plan for the tool is to integrate directly with Commons, Wikisource and Wikidata to help the users upload directly to Wikimedia projects and bypassing the IA Upload tool. To achieve the same, I need to integrate MediaWiki OAuth in BUB2.
We recently migrated to wmcloud from Toolforge hence that would require a different callback URL.
