If OSM is just a unique repository of hand collected data, sure,
that's right.
If OSM is an end result (e.g. published maps) then we should be
talking about how valuable the particular data is to viewers... or
creating a way to merge the hand-collected repository with other
quality repositories to produce useful mapping products.
Which is the more important goal? I hope the script I'm working is
compatible with either goal, and helps by improving the quality of
imports that are done.
even if you can't be convinced to put this information in the
changeset (which would be preferable as Frederik told you as well),
please consider using just one tag. E.g. source:license is not
important once the data is in OSM: all OSM data is distributed under
the same license. Source:website is information that doesn't belong to
the dataset IMHO, it would be better put (together with the license
information) on a wiki page.
source:license was meant to point to the license documentation that
permits the import. I don't mind leaving it out, or moving it to the
changeset.
source:pkey has to remain on the node/way, as that runs the conflation
process.
I will extend JOSM as needed so the changeset tags can be set
automatically (the whole goal here is automation and repeatability).
If I understand well, the set of data (car sharing location) first
imported is already a conflation of existing data in OSM and new data
given by the agency.
Some people said that the source tag seems more accurate on the changeset.
So maybe the source=my_agency may be wrong when the data is coming from
a previous conflation, but I need it for maintenance.
If I still understand, the function of the tag on the object (way,
node...) is to maintain synchronisation, and when the tag is destroyed,
the conflation is stopped.
So why not rather use a sync:*=* tag ?
The sync key is still not used (on taginfo Data from: 2011-08-26 00:00
UTC). Write a proposal... I would approve.
