Initial Situation
In a system where there are over 300 data providers (transport companies) and at least as many data recipients, certain specifications in the form of standards are essential. In the overall context, all parties must have the same understanding of what a stop is and also be able to clearly identify a specific stop. This information must then be transmitted correctly and consistently across all interfaces.
System management only sets out binding specifications in two areas:
- Structural standards: overarching specifications, such as how objects at the Swiss Union of Public Transport are defined and identified.
- Interface standards: based on interface standards that usually exist, the versions specific to Switzerland are set out precisely in the form of implementation guidelines.
All standards declared binding by the Management Board for Switzerland’s licensed transport companies are listed below as downloads. Previous versions and documents in the process of being drawn up are also listed where possible. There are also links to further supplementary documents.

1. Structural standards
Structural standards ensure the same understanding throughout the entire system of the Swiss Union of Public Transport. Some structural standards have been produced in cooperation with the Transport Customer Information Committee of ch-direct.
All structural standards validated by the SKI Management Board are summarised in this table. The status provides information on the progress of the item in the overall validation process (for planning, see SKI Roadmap).

2. Interface standards
In total, there are over 50 interfaces in and out of the systems of the Customer Information System Tasks. The following graphic provides an overview of the underlying standards, including their issuer. The overview contains both currently used as well as planned standards.
For some interfaces there are specific Swiss implementation guidelines that require further specification of the existing standards. The working groups are responsible for drafting.
