time-based tagging

Tags may be time-dependent. Perhaps a road is closed for some hours on certain days of the week for a type of vehicle. A bridge may be open only at special times... time-based speed limits, parking restrictions, and so on. It is impossible to think about all the possible cases.

Thus a method is needed to define that ANY key can be valid,invalid or changed depending on the time.

  • key_timedvalue_(Keyname)
    • {string defining values of a key for certain timeslots}
      • Example: key_valid_way_lanes="h=8-16,d=0-7:2;h=16-8,d=0-7:1" could be used to describe a road that changes the number of lanes every day a week at 8 and 16 o'clock.
  • key_valid_(Keyname)
    • {string defining timeslots the key is valid}
      • Example: key_valid_path="m=4-9" makes the path accessible in the summer, else it is ignored.
  • key_invalid_(Keyname)
    • {string defining timeslots the key is invalid}
  • key_valid_until_(Keyname)
    • date+time
      • Example: temporary alternative road because of construction area
  • key_invalid_until_(Keyname)
    • date+time
      • a road that currently is in construction
  • key_valid_from_(Keyname)
    • date+time
  • key_invalid_from_(Keyname)
    • date+time

So... ferry timetables can be embedded into the map data this way, too: just open the last piece of road at the harbour the right times ;) It is of course possible to do a lot of stuff with the time-based tagging that just makes no sense.

A flexible scheme to represent the different timeslots has to be found.

Hi Wollschaf,

while you refer to attributes still in service, maybe its you who can give me a hint to the historic dimension, as the saying goes, by when a road is build, by when a certain part of a castel ist build (and destroyed). This would enable to travel in time through the map (then obviously infinite maps) for which tags have to be invented. This is a must and would extend WikiPedia to the utmost.... scoid 21:48, 23 Aug 2006 (BST)


Hi, User:Bruce89 has sugessted to change the value for the Proposed_features/Pedestrianised_road from pedistrian to precint. So I think its the best to start a new voting period. Can you please go to that page and vote again? Sven Anders 11:33, 20 September 2006 (BST)

OpenGL OSMplotter in 3D?

Hey Wollschaf,

I'm also working on some OSM 3D app to for browsing (see my user page), I'd like to contact you for sharing ideas and/or contributing, please email me :)

Ich wollte nur mal kurz Hallo sagen. Ich wohne in Mannheim-Wallstadt und habe als Kind in Gorxheim gewohnt. Weinheim hast Du ja schon echt gut hinbekommen :-) -- LosHawlos 15:21, 4 May 2007 (BST)
