[Imports] Blog post about imports

[Christian Quest]

Serge, most of the problem you're mentioning in your post do happen without
imports. Imports just make them happen more often because of the amount of
data involved.

The bicycle parking example happens without import. Someone adds a POI at a
the wrong location, then someone else add it (again) at the right
location... or the reverse !

Most problems are mostly related to the ratio of data vs contributors in a
given area.

Regarding import related tags, some are really useless, some like unique
IDs have not been sucessfully used in many cases up to now, but this
doesn't mean we will never be able to take advantage of them.

Differential imports are not easy to manage especially when the imported
data have been manually updated. Regarding the cadastre building imports in
France, we have a couple of tools helping to update building data. They are
not fully automated and easy to use to be mainstream, but this is a work in
progress.
