Application of the RRP

The RRP can be selected in the schema creation wizard at DATEX II webtool.

  • If you want to implement the RRP “as-is”, you simply click through the wizard starting with the default selection of the package in the first step.

You skip Step 2.

Choose the respective RRP in Step 3.

In step 4 you select the location referencing method(s) you are going to implement.

Then you skip the subsequent steps and choose which type of output (XML Schema or JSON Schema) you want to produce in Step 6.

These schemas will then be used by the implementer of your RRP to create the interface software, e.g. by application of data binding.

If your service manages more data elements which have not been selected in the RRP, it is possible to extend the profile in Step 5 by selecting further elements.
