I setup user-config.py file with osm family to connect to OSM Wiki
import pywikibot site = pywikibot.Site() item = pywikibot.ItemPage(site, "Key:amenity")
Crashes with
AttributeError: APISite instance has no attribute 'item_namespace'
despite that item namespace exists - see https://wiki.openstreetmap.org/wiki/Key:amenity with "Data item" in the sidebar

I guess APISite is the problem which must be DataSite interface then. The usual way is to get the repository from APIsite site:
repo = site.data_repository()
item = ItemPage(repo, <title>)
repo = site.data_repository() item = pywikibot.ItemPage(repo, "Q4980")
works, but it does not solve anything as
repo = site.data_repository() item = pywikibot.ItemPage(repo, "highway=motorway") print(item) repo = site.data_repository() item = pywikibot.ItemPage(repo, "Tag:highway=motorway") # fails with 'Tag:highway=motorway' is not a valid item page title print(item)
still fail - and what I want is to get a matching data item for a given page ( https://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway )
So far I found code that simply fetched every single data item and cached all of them.
Vorpalblade77-kaart at OSM Wiki tracked down https://wiki.openstreetmap.org/w/api.php?action=wbgetentities&sites=wiki&titles=Key:bridge:movable&languages=en|fr&format=json that can be used as an workaround, thanks!
Key:amenity is a regular page, not an item. You should be able to access the item through:
import pywikibot site = pywikibot.Site('en', 'osm') page = pywikibot.Page(site, 'Key:amenity') item = page.data_item()
However, OSM is not a DataSite. When I update the family file, it throws ValueError: Cannot parse a site out of wiki. because of a sitelink to wiki (local page?).

https://github.com/matkoniecz/data_item_spillover_cleanup/blob/master/data_item_extractor.py has some code that (partially) parses this response into something usable (I have not found any way to get data using normal pywikibot code)
osm is its own DataSite
>>> site = pywikibot.Site('osm:en')
>>> repo = site.data_repository()
>>> site
APISite("en", "osm")
>>> repo
DataSite("en", "osm")
>>>but there are some problems with supporting osm:
item.get() loads the content and stores it in _content attribute. The problem is the initializing after that:
# make use of lazy initialization (T245809)
print(self.DATA_ATTRIBUTES)
for key, cls in self.DATA_ATTRIBUTES.items():
value = cls.fromJSON(self._content.get(key, {}), self.repo) # <-- this will fail
setattr(self, key, value)
