It would be more logical to have the date construction started be start_date,
and the date construction completed be completed_date. Having the completion
date tagged as start_date doesn't make sense.
I disagree, because start_date is the beginning of the tagged feature,
this is IMHO not the date when someone first thought about it, or the
plan got approved or the construction started but it is the date when
the feature was actually there as it is now.
partly disagree.
If I tag a construction site, I can add start_date - describing "start
of construction". If the building is finished, it's no construction site
any more, but the osm object may be the same one; re-tagged as
building=yes without construction and start_date describing the date the
building is finished "as it is now".
start_date, as you see in this example, is a generic tag, like e.g.
width is.
Refinements like start_date:construction, start_date:usage;
start_date:planning; start_date:disusage; start_date:abandonment are
possible - but start_date should not be used to be one of these.
