[Imports] RFC - Import of Electric Car Charging Data from Open Charge Map

I am involved with Open Charge Map ( http://openchargemap.org/  ). It is a
project similar in style to OSM but it store charge point data for electrc
car charging locations worldwide.

It is currently a mix of crowd-sourced data, where anyone can enter the
location and details of an electric car charging location, and imported
data from various public and commercial databases (with permission). Much
of the imported data is currently not able to be licensed under the OdBL
and so this data would not be a candidate for importing into OSM but I am
hoping that we can get all the OCM data licensed under a compatible open,
share-alike license and so eventually I am hopeful that the entire database
might become eligible for import.

However, for now, there is some 2563 manually entered (not imported)
chargepoints on the database that is eligible to be imported to OSM.

I propose that only these eligible ones be imported to OSM as single nodes
with the tags following the proposed Charging Station tagging (
Charging_station<http://wiki.openstreetmap.org/wiki/Proposed_features/Charging_station>).
I also propose an additional tags to hold the OCM references to allow for
cross referencing. This will also provide an easy way to determine which
data was imported from OCM. I suggest OCM:ChargePointID & OCM:AddressInfoID

This import would comply with all the OSM Import Guidelines.

Import would be staged country by country. Countries with small volumes
would be added first (there are many countries with just one on OCM at the
moment). Counts of ChargePoints on OCM that are currently eligible for
import by country are approximately (taken from recent backup of OCM):

ChargePoints Manually Entered  :     2563

ChargePoints Manually Entered By Country : GB :    772
ChargePoints Manually Entered By Country : US :    566
ChargePoints Manually Entered By Country : BE :    269
ChargePoints Manually Entered By Country : FR :    260
ChargePoints Manually Entered By Country : HK :    189
ChargePoints Manually Entered By Country : CA :    154
ChargePoints Manually Entered By Country : DE :    69
ChargePoints Manually Entered By Country : AU :    49
ChargePoints Manually Entered By Country : NL :    40
ChargePoints Manually Entered By Country : MC :    36
ChargePoints Manually Entered By Country : JP :    29
ChargePoints Manually Entered By Country : LU :    20
ChargePoints Manually Entered By Country : IS :    16
ChargePoints Manually Entered By Country : CH :    13
ChargePoints Manually Entered By Country : IE :    11
ChargePoints Manually Entered By Country : AT :    9
ChargePoints Manually Entered By Country : LT :    9
ChargePoints Manually Entered By Country : EE :    7
ChargePoints Manually Entered By Country : ES :    7
ChargePoints Manually Entered By Country : DK :    4
ChargePoints Manually Entered By Country : VU :    4
ChargePoints Manually Entered By Country : BR :    3
ChargePoints Manually Entered By Country : PT :    3
ChargePoints Manually Entered By Country : AL :    2
ChargePoints Manually Entered By Country : IM :    2
ChargePoints Manually Entered By Country : NZ :    2
ChargePoints Manually Entered By Country : AF :    1
ChargePoints Manually Entered By Country : BB :    1
ChargePoints Manually Entered By Country : BY :    1
ChargePoints Manually Entered By Country : CL :    1
ChargePoints Manually Entered By Country : FI :    1
ChargePoints Manually Entered By Country : IT :    1
ChargePoints Manually Entered By Country : NO :    1
ChargePoints Manually Entered By Country : PL :    1
ChargePoints Manually Entered By Country : SK :    1
ChargePoints Manually Entered By Country : UM :    1

There are currently 13063 ChargePoints that are not currently eligible for
import due to uncertain licensing, however we are investigating switching
OCM over to the OdBL and so once we get written approval from the data
providers to this re-licensing they will then become eligible to be
uploaded also. This re-licensing may or may not happen and timescales for
this relicensing is currently not determined so, the only eligible
ChargePoints will be those that were manually entered into OCM as they are
the only ones that are currently absolutely compatible with the OSM license.

It is hoped that as publically available charge stations get tagged into
OSM so they could then be used for route planning and real-time routing of
electric vehicles.

I would also like to point out that I am not the main developer in the OCM
project. It is currently funded by a charity (Zero Carbon World Ltd in the
UK). Although I am an experienced software developer I am still very much a
novice at OSM. I am planning on discussing every move before any decisions
are made or actions taken regarding imports. In the meantime I may manually
add some stations just to get a flavour for the tagging requirements.

I realise that this is the very first stage in developing an OCM/OSM import
but I would be very interested in any comments.
