Steps
Obtain the SIRI XSDs and documentation from the CEN-managed GitHub repo (SIRI-CEN/SIRI), corresponding to CEN/TS 15531
Identify which SIRI functional service is needed, e.g. Stop Monitoring (SM) for stop arrivals, Vehicle Monitoring (VM) for vehicle positions, or Estimated Timetable (ET) for trip-level predictions
Check for a national profile (e.g., a UK SIRI profile, or an agency-specific implementation spec) since base SIRI is broad and real implementations often constrain it
Implement or consume the request/response (or subscription/publish) exchange pattern defined for the chosen functional service
Cross-reference SIRI stop/line identifiers against the corresponding NeTEx or local static dataset to resolve human-readable names
Known gotchas
SIRI is a European standard with many regional profiles (UK, France, Norway/Entur, etc.) that are not fully interchangeable — code written against one profile may not parse another's SIRI XML correctly
SIRI supports both a request/response mode and a subscription-based push mode; assuming only one pattern is supported by a given producer can break integration
