[OSM-talk] what can be mapped - temporary, pernament and reoccuring

Some features are always present and are indisputable mappable - like
Some features are seasonal but are easily verifiable all the time as they
merely change the form. For example an intermittent river - riverbed is
always there, nearly always with obvious indications that water flowed
there some time ago.
There are features that obviously should not be mapped - with objects like
vehicles in motion being the extreme example. Other obvious examples are
events - OpenStreetMap is not a place to map events that happened in the
past or will likely happen in the future. One may still map memorial
plaques or monuments or football stadiums, but OSM is not place to mark for
examples places of famous robberies or crash sites of aircraft or planned
locations and dates of matches of a soccer tournament.
But there are also features that are possible to survey only during
specific circumstances and unverifiable otherwise. For example shops in a
mall building closed during night - verifiable only during opening hours,
with building interior inaccessible otherwise. Other example is a shop
without sign, or with movable sign placed on a sidewalk during opening
hours - such building may be after closing indistinguishable from
residential building with a garage or a vacant shop with type of the shop
nearly impossible to guess. Or a street vendor - somebody may be regularly
at given location within his/her opening hours, after that time such place
would be indistinguishable from any other party of the street. Or movable
loungers, present at the same location each spring, summer and autumn,
removed for winter. Or a flea market present on each Tuesday, regular
street otherwise (maybe with some street markings).
I think that all cases like that may be mapped, and I plan to amend "Good
practice" wiki page to explicitly allow features that are reoccurring and
to explain that they are not included into "temporary features" that are
not supposed to be mapped.
