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.

Here you can look into updated extensions.

If you want to upload an extension yourself, please log in to your datex2 user account and upload your content by clicking on  in the user account menu on the bottom of this page.
