"textContent": "Generally speaking, Lifecycle Prefixes mean that when something is no longer in use, a tag such as `amenity` gets changed to `disused:amenity`. That should be straightforward, but sometimes `disused=yes` creeps in.\n\nThis example overpass query for `nwr[\"amenity\"=\"fast_food\"][\"disused\"=\"yes\"]({{bbox}})` finds a couple of examples. In these cases we can have a look at the tag history and (as seen in the picture at the top) notice that the FHRS ID changed recently, and the `disused=yes` actually corresponded to the name of a different business on the same site (in fact that that one has the full set of such tags: `[\"amenity\"=\"fast_food\"]`, `[\"disused:amenity\"=\"fast_food\"]` (which don’t make sense together) _and_ `[\"disused\"=\"yes\"]`. In these cases you can often look through the tag history and see what the current status is supposed to be; if the last changeset comment was “this has now closed” it’s fairly obvious.\n\nSo does `disused=yes` _always_ mean that someone has forgotten to change something to a lifecycle prefixed version? Well, maybe not. As an example, what about this former quarry? It’s not used as a quarry any more, but it is still a very big hole in the ground, so it makes sense to show it as such. Maps that I create distinguish between operational quarries\n\nand historical ones\n\nso including `disused=yes` in the latter category was straightforward.\n\nWhat else might `disused-yes` occur with?\n\nQuite a lot of the landuses don’t need any change at all. For example `landuse=brownfield; disused=yes` is something that people have tagged, and landuse=grass; disused=yes is also around; it usually means that _something else_ (perhaps no longer tagged!) is disused.",
