<p>Thanks for your replies. Linking to subject:wikipedia and <font
face="monospace">subject:wikidata</font> is supposed to help
people looking up what they're looking at, I always presumed. "oh,
there is a plaque here about such and such a person, I wonder what
else they did apart from being born in this house". I just
checked, and not even the Kilpeck Sheela has her own Wikipedia
article, even though she is the example used everywhere (because
she was one of the first to be described by scholars, I presume).
The tags subject:wikipedia and subject:wikidata could be
automatically generated like it is done with brands, I guess.<br>
</p>
<p>I don't think it can be compared with linking to the wikipedia
article about water, because everyone has a fair idea what water
is and the numbers of features tagged with <font face="monospace">natural=water</font>
and the potential <font face="monospace">artwork_subject=sheela-na-gig</font>
are quite different.</p>
<p>I agree that the <font face="monospace">artwork_subject</font>
key is a mess, but that is an argument I have heard for several of
my proposals, and just because I became very active on OSM when
there was a mess already cannot mean that my proposals should be
rejected.</p>
<p>I'm also not a fan of <font face="monospace">key=yes</font>
tagging, when there is no <font face="monospace">key=no</font>
option.<br>
</p>

<div class="">this is (or should be) generally the case for
all "...wikipedia" and "...wikidata". <br>

<div class="">Our data should be self contained (not sure if
this is the right term, I mean that the semantics should be

<div>There doesn't seem to be a conceived system behind the

<div>the second most used value, "religious", has potential
overlap with all the other values (and could possibly be
expressed with the standard religion=* tag), although with
some few it may be less likely (e.g. lgbtq). There are
only 3800 objects with this tag, and you cannot see yet
where it may evolve to. The documentation is a bunch of
referrals to wikipedia, so that they will change by the
time without us noticing in the OSM-Wiki<br>

<div dir="auto">I agree, though my conclusion would be "and
therefore this tag should be avoided,<br>
</div>
<div dir="auto">using some other scheme that will not be very
likely to be problematic in future<br>

<div dir="auto">should be preferred"<br>

<div>IMHO not. It would not provide context unless you knew
what "sheela-na-gig" was, better put it in the value.<br>
</div>
<div>If you wanted to use sheela-na-gig as a part of the
key, why not sheela-na-gig=yes?<br>
