the same thing if there were no Cadastre to import? No, you couldn't.
Cadastre is an import.
Cadastre is sometimes an import, sometimes not. Using the same data
source, you may upload tons of buildings, or draw a single house thanks
to cadastre WMS-like service as a background layer. In the end all
buildings, without any difference, will get the "Cadastre xxxx" source tag.
For instance :
this one is from an "import" :
http://www.openstreetmap.org/browse/way/63994077
this other one was drawn manually :
http://www.openstreetmap.org/browse/way/181674272
Both have the same source tag, which is a request from the French
Cadastre authority.
A reason for a dedicated import account (read above in this topic) is
that it helps to make a distinction between data sources in case of
incompatibility between the source and a new licence. Let's assume
French Cadastre Authority changes its mind and revokes any right to use
its data in OSM. Cleaning the database will not consist in reverting
changeset of "imports", no. The only criteria for removing French
Cadastre data will be the value of the source tag. Both buildings above
will have to be suppressed. it is not a matter of import here.
A lot of contributors mapping in France use Cadastre in such both ways :
massive uploads and single edits using the same source. Such a mix make
a dedicated account useless in this case. That's why I think that, as
you say Richard :
- "Cadastre is different;
and does not apply for a separate account.
