I want to suggest the following feature to the next API : valid_per tag supported
- API will return only data of which the valid_per argument evaluates to TRUE - A standard delete action may just set the expire_per tag to "expired per today". The tags will need some regular expressions to it to allow for visible on all Mondays, weekdays, time of days , holidays Default (untagged items) are always valid of course. This allows for: - tagging items that are known to be exist only for a limited time (expositions, art projects and others) - setting areas under construction to an appropriate state for a defined span of time - drawing both current and future situation in a supported way (when new plans are known), this prevents the google maps problem of drawing non-existent roads and even quarters - allow for bus routes and other with time varying items be drawn correctly (great support to route planning) (tag on relation) - draw historically correct maps This proposal will certainly need some refinement, please go ahead and suggest so...
