so when you see the amenities tag, split on ';' or whatever, trim the
result and insert a row into the database/file store for each result.
it doesn't seem that hard to me.

in any case, it seems like the "amenities" key suggestion is rejected
by all sides. certainly no-one is using it in the wild.

the impression i got from "the current namespace ...
transition-period" was that you intended to run a bot continuously
over the data to keep amenity=xxx and amenity:xxx=yes in sync. sorry
if i misinterpreted - as long as it doesn't involve bots, i don't mind

the people seem to have already decided (see blackadder's email).

and ask some of the water to turn into gold, so you can go buy a pump. ;-)
