[Tagging] Proposal of electricity=* and electricity:origin

[Lukas Richert]

Hello all,

after the comments on the confusing nature of the word 'source' in my 
original proposal of 'electricity:source', I have now changed the name 
to 'electricity:origin' as suggested on the discussion page. 
Furthermore, I would like to revive and extend the proposal of the key 
'electricity' as this previously conflicted with parts of the 
electricity:source proposal and was not consistent.

Both proposal pages:

[1] https://wiki.openstreetmap.org/wiki/Proposed_features/electricity

[2] 
https://wiki.openstreetmap.org/w/index.php?title=Proposed_features/electricity:source

The idea now is to allow for the tagging of buildings or amenities that 
have electricity. The rationale is described in more detail at [1]. Tags 
such as access, fee, schedule and origin can then narrow down the 
availability to the public and the question of financial or direct 
origin of the electricity.

This is distinct from the drafted tag power_supply as it is used to 
describe the type of sockets used at a specific outlet. The values for 
that tag are still currently under discussion.

I would also not tag this as a subset of power=* as this maps the 
facilities and features that relate to the generation and distribution 
of electrical power and should not be used to map the consumers of 
electricity.

I am eager to hear the feedback to the revised proposals!

Best regards,

Lukas
