I assume that disused=yes could also be used on bunkers, as they<br>
usually have no other function today. So there is no confusion with<br>
any other tags to which the "disused" could be applied.<br></blockquote><div><br></div><div>I would say disused applies only to things that are not used at all,</div><div>as opposed to conversions.

Pubs appear in a</div><div>lot of website listings (beer guides, reviews, etc.) and armchair mappers</div><div>spotting one of those may add a pub that is no longer a pub. Consumers</div><div>may spot a pub in one of those guides and look for it on the map, assuming</div><div>that if a building has the same name as the pub (as several pub conversions</div><div>I know of do) that it really is a pub. Using was:amenity=pub or</div><div> disused:amenity=pub as appropriate makes the map slightly more useful.</div><div><br></div><div>-- <br></div><div>Paul</div><div><br></div></div><div class="gmail_quote"><br></div></div>
