Hi,

I agree that parking tagging needs to be unified in some way. Last year 
I worked on the proposal to introduce conditional tagging to parking 
lanes, which was approved. I only considered that a stopgap solution as 
there are differences in tagging for parking areas vs parking lanes that 
cannot be reconciled without fundamentally changing either one or the 
other. I would like to explore some way of unifing this tagging, and I 
think that using the 'parking:' namespace would make the most sense. The 
problem I see is that when dealing with areas, the parking is the main 
feature which allow the use of top-level tags like 'access=*', 'fee=*', 
etc, while parking lanes are a secondary feature on highways like 
sidewalks or shoulders where you can't use them as they would refer to 
the highway and not the parking feature.

Also, like I've previously said in another communication channel: great 
write-up on the wiki!

Best regards,
