I'm going to wind things back in a bit here as the discussion seems to
be widely disjointed.

I think there needs to be a formal discussion as to just what secondary
data sources are preferred when adding additonal data to OSM objects.
Wikipedia is a useful secondary source for a vast range of material, but
some objects in OSM will not be 'notable' enough for wikipedia to allow
an article to exist, so an alternative mechanism is needed for those
objects. wikidata may well be a suitable alternative, but the simple
fact that a more detailed article for a wikidata object by not be
accepted makes wikidata something of a problem as well. While
wikipedia/wikidata provide a sort of standard framework for additional
data, the primary link from an OSM object should perhaps be to websites
specific to the object rather than the filtered wikipedia view of the
world?

Some of the tangential debate has been re ADDING links to OSM object
that have not yet been tagged with something suitable, and this is where
cross matching these items depends on the information already available
on in the OSM tags. I have still to be convinced that wikidata is
'independent' enough to be a reliable source of cross-reference links,
especially where other reference tags are already used. UK Schools we
have added the reference from the schools database. I've not looked to
see if a wikidata 'view' of that data is available, but I would not look
to add wikidata id's in addition to the school id's - BUT the wikipedia
reference has been added where the schools are notable enough to warrant
an article. I WOULD only look to tidying these objects to ADD the
wikidata id if one was also checking that all three elements are
correct, rather than simply automatically adding them. Whilst I was
processing that data during the UK group push on it there were often a
lot of corrections made to get the right 'set' of data on a school
object. While only a small number of objects were actually wrong, that
is enough to justify needing a manual cross check of some sort.
