SIRI references pointing to ScheduledStopPoint instead of Quay

[leonardehrenfried]

Background

South Tyrol in Italy has a SIRI feed where the <StopPointRef> elements point to ScheduledStopPoint and not Quay.

After a lot of discussions with the NeTEx authors as well as the Entur authors, we agreed that OTP should support ScheduledStopPoint references in SIRI as well as Quay.

Design

To achieve this I propose the following design:

Here is a diagram showing the NeTEx data model and its closest equivalent in the OTP model.

Here are the key data flows:

• TimetableRepository will have a new map from ScheduledStopPointId to QuayId
• This collection is filled during the graph build
• TimetableRepository is then is then injected into TransitService which is injected into the SIRI updaters
