Reisidest

Reisidest is a term used in the field of travel planning to denote a unique identifier assigned to a specific travel itinerary within a digital system. It functions as an internal reference to distinguish one itinerary from another across services such as search, selection, and booking.

Etymology and terminology: Reisidest is not a standardized term with formal etymology. The component reis- evokes travel in several languages (for example, Dutch reis and German Reise), while -idest is a suffix sometimes used in internal labeling. The combination is primarily a practical label in software contexts.

Definition and role: In data models, a reisidest acts as a stable key that uniquely identifies a particular itinerary version. It may accompany other identifiers such as user IDs, booking references, or timestamps to support versioning, synchronization, and auditing.

Usage and examples: In a travel app, a response from a search query might include a reisidest field, which a client uses to fetch full itinerary details via an API endpoint like /itineraries/{reisidest}. The identifier helps decouple human-readable descriptions from the underlying data and supports consistent referencing across modules.

Benefits and limitations: Reisidest supports consistent references across modules, caching, and cross-system reconciliation. It is typically not shown to end users, and care is needed to avoid exposing sensitive information through identifiers. Documentation and stable versioning are important for long-term reliability.
