there are two problems:
1) a list of some local default exists (e. g. speed values according to
the type of road per country). the problem is the lack of a schema to
assign these values indicated on the wiki to the osm data.
every router for exemple have his own not-opensource-opendata schema to
retrive those value.
there is an unsuccessful default value proposal but unfortunately nobody
has been working on it for a long time.
2) Even if this list exists, the other problem Fernando mentioned is
that it is impossible to tell the difference between someone who added a
street without checking the details (number of lanes, cycleway, ...)
that someone who checks a road and fill all tag that are not the same as
the local default value.
in this usecase, a key like defaults=checked would be interesting.
or something like survey:date + survey=default
otherwise, do not hesitate to suggest a way to indicate that you have
checked the secondary tags on 200 roads in a city so that another
contributor knows which street is completely described and which one is
not. or how to make a one-year check to tag change in oneway street.
My usecase is the trick of marking streetlights when I have completely
finished a street. since the only one doing it around here, I always
know witch are still to be done. there should be a more serious way to
share this kind of information.
