Hello, by testing, it looks like application of, eg, |show=arts or |country=ja returns a reduced number of results from wikidata; there are number of wikidata properties that would be relevant for Japan-related pages, eg P4275, P12144, P12145, P4257, P9080 (with a couple more imminent, inc. P?????); there are thousands of pages for which these would be directly relevant, but they shouldn't clutter and make less efficient/more energy intensive the authority control for non-Japan-related pages; to have these added, without removal of other properties, would you populate the ja whitelist with the full authority control list, then add to this, or is there a way to add a smaller numer of ja-specific properties to the standard list (likely many of those at Template:Japan properties), via an additive equivalent to whitelist? I haven't raised it there yet, but would it be possible to run a bot to add this parameter to the authority control for all pages where the talk page is linked to Wikipedia:WikiProject Japan?

It is not possible to do this currently. Adding a new identifier will add it to all pages, unless there are restricting them with |show=. I suppose we could make a default list of identifiers, and then if you wanted to add to these you could use something like |show=default, JA. Or perhaps a new parameter like |show_also= — Martin (MSGJ · talk) 08:47, 14 March 2025 (UTC)[reply]
In that case, it might be clearer to rename "show" to "show_only". What should happen if "show_only" and "show_also" are used at the same time? — Martin (MSGJ · talk) 19:05, 25 March 2025 (UTC)[reply]
As an initial step I have added a default set of properties to Module:Authority control/config/sandbox which consists of all the current properties. If you add any more to the sandbox, then you can test if a combination like |show=default, ja works as expected — Martin (MSGJ · talk) 21:37, 1 April 2025 (UTC)[reply]
Seems to be of limited value to English readers/editors, but if this is something akin to a national library then I could be convinced — Martin (MSGJ · talk) 21:27, 23 April 2025 (UTC)[reply]
