Extension Directory

DATEX II models can be extended using extensions. The following conditions must be kept in mind:

  • DATEX II can be extended with application specific extensions.
  • Extensions are recommended to be done in the UML model. Users are strongly discouraged to manually edit the generated schemas.
  • A level A model can be extended and will then become a Level B if the Level B extensions rules are respected. If not, the model will become a Level C model.

In here you can look into updated extensions.
