[Ovmsdev] Sharing Data Publicly - Public Charges

From a user point of view, what do we need?

I guess, for each station:

a) An indication of when someone last charged successfully
b) A 'star' style rating system to tell me how reliable it is
c) Pictures
d) Instructions
e) Comments

I think OVMS can help with (a) and (b) primarily.

Regards, Mark.

> From my personal point of view this all sounds good, OCM is probably not the best place to store very fine-grained charging stats and is mostly interested in aggregated summaries instead - basically high level info that's useful from a user perspective. While OCM is indeed focused on charging location information we also need to help users by identifying quality/usage information (good and bad) with locations which is where comments/checkins comes in. We augment that with photos to allow users to illustrate stuff about the location.

Obviously thats up to you but probably the simplest integration. We don't want to hold information of charging locations at private residences (someone's home) as the data protection/privacy issues are too complicated.

Privacy is my main concern, infringing other peoples data license is obviously undesirable too, to varying degrees. People can get very upset about licensing, very quickly.
