fare_rules.txt and a conditionally required agency_id about transit HOT 9 CLOSED

I think that we should add fare_attributes.agency_id to add to the spec. Trillium currently supports this in order to specify fares in multi-agency feeds (e.g. https://transitfeeds.com/p/arcata-mad-river-transit-system/148/latest/file/fare_attributes.txt). I suspect this is broadly used, but am not sure.

@antrim have you seen the discrepancy in my comment?

@skinkie : I didn't follow everything, particularly the part about "allow multiple agencies sharing the same route_id". I noticed that you're discussing both fare_rules.txt and and fare_attributes.txt but didn't parse everything out. Instead, I thought it was simpler to just share Trillium's practice. If there's more to explore or a correction/clarification to make, please share!

In order to merge a feed the tripids of feed A and B must not have any value in common. The same would go for route_id. Hence you can't have a route_id and trip_id combination that is less unique than a agency_id, route_id and trip_id. I wonder if it therefore would make sense to have an agency_id, if agency_id is in fact an attribute and not a compound key.

Yup! I was thrown off by this:

Google Transit seems to have received a private extension to have an agency_id added in fare_attributes.txt

fare_attributes.agency_id is already part of the spec.

I'd favor leaving fare_rules.txt as it is. Could we close this issue?
