Hi!
Maybe someone can help me defining the following access restriction
using the 1.5 proposal:

I think I found a solution using a self-defined rule:
access:motor_vehicle!rule.time=10:00-18:00
access:motor_vehicle!rule.width=5+
access:motor_vehicle?rule=no
Can this be simplified somehow (using the 1.5 proposal)?

With the access 1.5 and default opening_hours syntax it would look like this:
define the rules for forward and backward:
• access!forwardrule.time=Mo-Fr 16:00-18:00
• access!forwardrule.direction=forward
• access!backwardrule.time=Mo-Fr 06:00-09:00
• access!backwardrule.direction=backward
apply
I tried to express this with the other proposal. I got this:
motor_vehicle:(Mo-Fr 16:00-18:00):forward=no
agricultural:(Mo-Fr 16:00-18:00):forward=yes
goods:(Mo-Fr 16:00-18:00):forward=yes
motor_vehicle:(Mo-Fr 06:00-09:00):forward=no
agricultural:(Mo-Fr 06:00-09:00):forward=no
goods:(Mo-Fr

You mean:

access:lgv?wet.speed=80
condition1=wet
maxspeed:lgv=120 or 80 in condition1

Hi.
I'm a little bit afraid about the discussion here and would like to
point out that a key IMHO should be different than a value.
I like the idea of namespaces for keys, to be able to group tags that
belong together, but I think, even namespaced stuff should belong keylike.

At first glance this looks like a motor vehicle going forward between
those times is considered agricultural. It doesn't feel very
intuitive, based on the established key=value paradigm.

In the UK agricultural vehicles are prohibited on motorways due to their slow

Martin, if it walks like a duck and quacks like a duck, then it had

I've only heard tailings used to refer to the waste from mining.
Regarding wastewater treatment, I'm assuming other reservoir_types
discussed were things like sedimentation and aeration?
