**Reason**
The MachineVision extensions was leading to more bad than good edits. See https://phabricator.wikimedia.org/T339902
**To-do list**
- This task
-- [+] Add maintainers of that extension/skin as subscribers to this task (if they have no apparent Phabricator account, notify them on-wiki or via email if possible and note it here).
-- [+] Add Phabricator project #MachineVision as a tag for this task, and remove #mediawiki-extensions-other/#other-skins as appropriate.
- Undeploy
-- [] Remove from config so that it no longer gets intialized in production ([[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1013284 | patch ]])
-- [] Remove any scheduled jobs ([[ https://gerrit.wikimedia.org/r/c/operations/puppet/+/1013329 | patch ]])
-- [] Once these are done and the patches deployed then drop from [[ https://codesearch.wmcloud.org/search/?q=machinevision&files=&excludeFiles=&repos=releng%2Frelease&i=fosho | releng/release ]]
- On-wiki documentation
-- [ ] Archive documentation on `mediawiki.org` (provide URL): replace page contents with `{{Archived extension|last revision id before archiving|task=T352884}}`
-- [ ] If documentation page was translatable, remove `<translate>`, visit Special:PageTranslation, and click "remove from translation" (if you don't have the translation administrator right, ask a [[ https://www.mediawiki.org/wiki/Special:ListUsers/translationadmin | user who does ]]).
-- [*] Update Wikidata item (provide URL) associated with documentation page
--- [*] add statement `Abandonware (Q281039)` to `instance of (P31)` together with qualifier `start time (P580)` = the YYYY-MM-DD date that you decided to archive extension/skin (generally per edit history)
--- [*] add qualifier `end time (P582)` = the YYYY-MM-DD (same date as above) to `instance of (P31) = MediaWiki extension (Q6805426)/MediaWiki skin (Q21996535)`
- Phabricator
-- [ ] Mark all Phabricator tasks for the extension/skin either Declined or Invalid. Add a comment pointing to this task when doing so for reference.
-- [ ] Archive Phabricator project #MachineVision for the extension/skin.
-- [ ] Edit Phabricator project #MachineVision description for the extension/skin with a link to this ticket.
- Translatewiki.net/translations
-- [ ] Remove from `translatewiki.net` ([[ https://gerrit.wikimedia.org/r/plugins/gitiles/translatewiki/+/refs/heads/master/groups/MediaWiki/mediawiki-extensions.txt | groups/MediaWiki/mediawiki-extensions.txt ]] / [[ https://gerrit.wikimedia.org/r/plugins/gitiles/translatewiki/+/refs/heads/master/groups/MediaWiki/mediawiki-skins.txt | groups/MediaWiki/mediawiki-skins.txt ]] / [[ https://codesearch.wmcloud.org/search/?q=ext-machinevision&files=&excludeFiles=&repos=translatewiki.net | and also here ]]).
- Configuration/tests/integrations/etc.
-- [ ] Remove tests in [[ https://gerrit.wikimedia.org/g/integration/config | integration/config ]] ([[ https://gerrit.wikimedia.org/r/plugins/gitiles/integration/config/+/master/zuul/layout.yaml | zuul/layout.yaml ]]).
-- [+] Remove manifest/other references from [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/vagrant/+/master | mediawiki/vagrant ]] if they exist. ([[ https://gerrit.wikimedia.org/r/c/mediawiki/vagrant/+/1006019 | patch ]])
-- [ ] Remove from https://doc.wikimedia.org/cover-extensions/ if present (requires #continuous-integration-infrastructure shell user to delete directly from the server).
- Repositories
-- [ ] Empty repository, leaving only the README indicating the repo is archived, and referring to this task by URL.
-- [ ] Remove from [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/+/master | mediawiki/extensions ]] / [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/skins/+/master | mediawiki/skins ]] (along with in `.gitmodules`).

-- [ ] Delete the GitHub mirror: (provide GitHub repository URL).
- Events
-- [] Remove all events and event schemas T347970
- Data
-- [] Archive db tables - just putting [[ https://dumps.wikimedia.org/other/machinevision/20240316/ | the latest dumps ]] someplace they can be found is probably enough
-- [*] sqoop data from production db into hdfs
--- done, available in hdfs at `/wmf/data/archive/backup/machine-vision-backup/`
-- [] drop db tables on production (and beta)
