Data sources

Every price in our database is traceable to a registered source with an authority level and a verification date. This page lists them.

Collection principles

Registered sources

This is a source register, not a list of live booking connections. “Registered” means the source is available to the data workflow; it does not mean every price or route has been imported. Use the verification date and validity window beside the actual fare or result. Development-only demo sources are not evidence for published prices and are omitted below.

About demo data

During development and in local installations, clearly-labeled demo records (grade demo) stand in for verified production data so the tools remain testable. Demo records are marked in the database and are replaced by collector-verified records before production numbers are presented as verified. Methodology details: how recommendations are calculated.
