I think some work has been done on Arlington National Cemetery which
might be relevant.
A couple of years ago I made this proposal:
attempts to capture this sort of requirement. The main interest was
European forests, but cemeteries were very much on my mind because it is
often really difficult to find a particular grave even in small cemeteries.
I don't know if anyone has used it (I wasn't particularly happy with the
tag name because its meaning is non-obvious) for tagging. Obviously it
is unlikely to be supported by renderers, although if you look at the
discussion you can see interest for some renderers.
I did do one cemetery but it was horribly tagged for the renderer & I
really ought to fix it!
I think admin_level is getting terribly overused (e.g., neighbourhood)
and would deprecate its use for anything except administrative
boundaries. I tend to think of it as a rendering hack anyway: and it may
force the data consumer to use the wiki to interpret it.
