We recently found imported users were being marked as anonymous users in MediaWiki History (MWH) T425735: interwiki imports and its effects on revision data. A new field event_user_is_cross_wiki was added to identify those users. But we don't have information about whether the original users were actually permanent/temporary/anonymous and whether it was a bot.
This ticket is to add these information in MWH. This information may be required in various metrics, most recently in Unique Editor Counts metric T426316#11979835 where we try to find permanent, temporary, anonymous, and bot editor counts.
It would have been ideal to get the user_central_id and user_id of those users. Transwiki imports link to the original user in the source wiki, so we should be able to find a way to get the user_ids. Example Wiki. It could also be non-wikimedia wikis: strategywiki>Garrett in this wiki
Upload imports, on the other hand, are not very consistent and do not link the original user. *>Hapa and more in this wiki.
