On a page Key:amenity - OpenStreetMap Wiki there was recently added entry for amenity=mailroom. However, it is shown as error in red color:
[[ Data item not found. Check your spelling. | mailroom ]]
I’ve tried fixing few obvious errors made by original editor (not updating id from copy/pasted block etc), but this error still remains.
That Data item sounds suspiciously like wikidata related Data items - OpenStreetMap Wiki , which I know next to nothing about.
The {{valuelink}} template manages links to tag value pages in multiple languages; from, for example, Hr:Map Features, it would link to a documentation page in Croatian if there is one, otherwise another language. There appears not to be a data item corresponding to amenity=mailroom, if the Data items bot was running one would have been created.
So, you suspect the Data items bot might be down? amenity=mailroom was added to wiki at 11 November 2022, which seems like it should be enough time for bot to pick it up?
If that is abnormal condition (which it looks like to me as an outsider), could I bother you @Wynndale to report it to people who are able to fix it (I don’t want to burden you; but you seem to be only one around here knowing what is going on)? Thanks in advance!
@nyuriks used to run Yurikbot to update and create data items based on infoboxes, but this bot hasn’t been running for some time. In the meantime, you can create a new item manually.
By the way, it isn’t enough to create the item with a matching label and give it a documentation wiki pages (P31) statement; you also need to set its sitelink using the link in the sidebar, so that the tag description page will link to the data item.
