The TIH Principles
The Travel Information Highway uses a 'common practice' approach to the exchange of travel information. This means that we only adopt practices that are both relevant to all our members and conform to international standards.
The common practices we have adopted are collectively known as the TIH Principles.
What is defined by the TIH Principles?
To effectively exchange information, the format of the data needs to be agreed in advance. If the data doesn’t match exactly what the receiving system is expecting to see, the exchange will fail. Following the TIH Principles makes sure that we all make our data available in a common format and using common standards for locations, event types, etc.
The TIH Principles do not compromise your data ownership, nor do they imply a data warehouse, they just capture the agreed framework for joining many systems together over the Internet, setting out the rules for these key areas of data exchange:
- The charging mechanism for data should be clearly described
- Security levels should match the value of the data
- Location references should follow international standards
- The format of the data should be described adequately
- Data should be published using XML (eXtensible Markup Language) for economy and ease of implementation
As you can see, there’s no mystique or complexity to the Principles – just some common-sense standards that we can all work with.

Setting up a travel information service?
