Thanks Tom, we can chase that up, or alternatively if you know people at these networks you're welcome to invite them to join OCM as a data provider (just CC myself and J-C Saint-Po) - we are generally trying to convince them to donate their information under a CC BY S-A 3.0 license (http://creativecommons.org/licenses/by-sa/3.0/) but we'll consider other terms as long as it means we can redistribute the information via our API etc. In general most US stations have come from either the DOE AFDC system or from Carstations.com (and these would probably have been a point of reference for other map providers as well). It would generally be better for OCM to pull from the networks own data sets however these are often locked into systems we're not permitted to copy from. Historically we've been flexible about our data sources (so OCM data has mixed data licensing terms which can be seen in the Data Provider section of each POI) but we're now pretty strict about getting explicit permission - for instance we got permission yesterday to redistribute another 600 Canadian locations under an open data license. De-duplication is a big and surprisingly complicated problem. Currently we will try not to add stations which are within 100m of each other specifically because it may just be the same location described differently. In general stations from the same network are grouped under 1 POI with multiple equipment details entries. The absolute best way to get the information correct is for you to edit things when you see that they're wrong, or add information if you see it's not there. I realise that's where it gets frustrating because you end up having to enter stuff into all the various apps you use. Thanks for the offer of the perl script, we have a fairly standardised import mechanism (written in C#, which is similar to Java) which you can see here (excuse the mess, several of these providers are not used): https://github.com/openchargemap/ocm-system/tree/master/Import/OCM.Import.Co...

That's a fair point, although I don't think it's especially proprietary since users can report the same information manually. The stations are all public.
I'd suggest contacting Kent Rathwell:
Kent Rathwell President and Founder Sun Country Highway kent@suncountryhighway.ca 306-612-4600 800-467-6920
If Kent says it's OK, but can't give you a nice data feed, my script may be useful.

I think that OCM needs to be mindful of copyright when taking data from other sources. In fact, I know that Christopher Cook of OCM is mindful of that. So unless the data at the Sun Country Highway Network is open source OCM will be cautious of "grabbing" data from anywhere.
This whole area of potential of breach of copyright and data licensing is something we all need to me mindful of. :-)
