This metric will help me generate a more meaningful WikiProject Watchers report https://en.wikipedia.org/wiki/Wikipedia:Database_reports/WikiProject_watchers

Further, having this information will help me evaluate the outcomes of my WikiProject work – using raw watchers is an unreliable metric, since some WikiProjects are several years old and have watchers who haven't edited in years.

Therefore, I would be happy to see "actual watcher" information exposed via the API. Thank you.

whoever closes this ticket - i think it may be good idea to redefine it as:

all data available via

action=info

should be available via api call

action=query&prop=info

whenever possible.
this will add a bunch of new "inprop" values, and should not affect any existing code not using those new values.

peace.

Looking through it:

• "Redirect target" is T31115.
• "Default sort key" could be added easily enough, although when it's non-default it's already available from &prop=pageprops as 'defaultsort'.
• "Page ID" isn't necessary from prop=info, since it's automatically returned by action=query itself.
• "Indexing by robots" could be added, although it would have to duplicate much of the logic from Article::getRobotPolicy() to avoid having to instantiate 5000 Article objects.
• "Number of redirects to this page" I'm not sure is terribly useful, if someone cares they could probably do better using prop=redirects.
• "Counted as a content page" could be difficult to do efficiently since it requires loading the Content object.
• "Number of subpages of this page" I'm not sure is terribly useful, if someone cares they could probably do better using list=allpages&apprefix=... (if meta=siteinfo reports the namespace has subpages enabled).
• Category information is available from prop=categoryinfo.
• Most of the edit history stuff is likely better done with prop=revisions. Total authors is prop=contributors. Recent bits, probably list=recentchanges&rctitle=...
• "Magic words" are in prop=pageprops.
• "Hidden categories" are prop=categories.
• "Transcluded templates" is prop=templates.
• "Pages transcluded on" is prop=transcludedin.
• A hook parallel to 'InfoAction' could be useful, although some of it (e.g. the page image) are better done via their existing prop modules (e.g. prop=pageimage).
