How do I denote a business is not yet open or has shut down?

1. For a POI that is not yet to be constructed, do not add it on OSM.

2. For a POI that its construction is in progress, add your data, but prefix the POI type key with construction: lifecycle prefix. This prefix will prevent your not-yet-open POI from displaying on the maps/applications in an inappropriate way.

   For example (node-type POI):

   construction:shop=convenience
   name=7-Eleven
   

   Which, once open for business, you can remove the prefix; turning it into:

   shop=convenience
   name=7-Eleven
   

   In case you have other information (like phone=*, opening_hours=*), you may add them if you wish. (May the verifiability be with you) Applications, as far as I figured, would not take them seriously if the POI is in construction or closed down.

   If said POI is also building-in-construction (way-type POI), consider adding building-specific building=construction, construction=* combo too; for example:

   building=construction
   construction=retail
   construction:shop=mall
   name=Zen
   

   Which, once open for business, you can turn it into:

   building=retail
   shop=mall
   name=Zen
   

3. For a POI that recently went out of business, prefix the POI type key with disused: . This will remove it from most maps/applications display.

   • If the sign is still there, you can leave other data intact.
   • If the sign is removed, then you can remove other information that is specific to the closed business. Leave other standing information, like address, and disuse-prefixed shop type, intact.
     • Note: If locals still know or call it by the old name, you might consider changing name=* key into old_name=* instead of removing it outright.
   • If the POI is also a building, keep those building-related tags intact.

   For example, a bottled gas shop, that is also a building:

   building=retail
   shop=gas
   name=Wang Gas
   opening_hours=08:00-16:00;PH closed
   addr:housenumber=123
   addr:street=Merry Street
   

   When it's out of business:

   building=retail
   disused:shop=gas
   name=Wang Gas
   opening_hours=08:00-16:00;PH closed
   addr:housenumber=123
   addr:street=Merry Street
   

   When its sign is taken down:

   building=retail
   disused:shop=gas
   addr:housenumber=123
   addr:street=Merry Street
   

P.S. If the POI is not just closed down, but also in a very bad shape (e.g. windows/walls falling down), consider using abandoned: prefix in place of disused:.

P.P.S. If the entire block or building got torn down, then you can just remove all information/sub-POIs inside it. (Also consider marking the area with landuse=brownfield if you see fit) Don't forget to note the fact on edit summary when saving your edit too, or otherwise people would think you were vandalizing the map.
