The simple case is boundaries, you might be able to use info from POIs
to create a boundary but I wouldn't use them to generate a map like
that.

is_in is being replaced with boundaries so you don't need to tag every
single node/way/relation with is_in same with addr:postcode I'm
guessing.

All the postcode boundaries in Australia have been tagged as
postal_code and were that way before I became involved so I'm not sure
if this is the best tag to use or not but it was already in use and
will keep getting used for consistency reasons.
