How to interpret conflicting conditional restrictions?

If the ferry should use foot:conditional, should the track use foot:opening_hours, if that is even a thing?

There is no need for a foot:conditional on a ferry. If it’s not operating you can’t access it. Same goes for e.g. a bus route or any shop.

foot:opening_hours is not used, that’s what the conditional syntax is for.

@alan_gr

I think it’s less clear when access:conditional is used.

First of all there’s a general problem with access and several conflicting opinions. Does access=destination on a path really allow all traffic including trucks or does it only refer to the traffic modes that are typically allowed on a path?

Then, the set of rules in the Wiki is given as an ordered list. I.e. if the first rule already applies, the others are not needed. That is, any specific transportation mode overrules any access tag, no matter if it is conditional or not.

@alan_gr

And I think the interaction between opening_hours and other tags is not really spelled out.

I think it’s the same everywhere: If a POI is not open, you can’t access it, so none of the access tags apply.

@alan_gr

there is also the question of how far we can rely on mappers correctly applying an evaluation algorithm

As the examples in the first post show: We can’t. But neither can we rely on mappers applying other tags consistently like recent discussions on maxweight or overtaking show.
