The DATEX II information model is a vast model for all kinds of information that is possibly exchanged in the traffic and travel domain. In operational practise the implementers of information links focus on parts of the model only, as these parts are relevant for their operational exchange requirements.
To manage this focus and in order to ensure the standardisation of subdomains, the concept of profiling is developed. In this guideline the way a profile can be defined to support a specific information link, is provided.
