Description of the rnv: "A very slim data set. Here we provide you with files for our rnv lines in XML and JSON formats, very reduced, even without history. There is not much more to say about this data set, because Otherwise, the data set is compiled identically to our data sets for lines with a stop reference. We have been offering new data sets since mid-July 2020. These are always up-to-date and replace the old data sets. The structure and content of the new data sets is described in the respective resource."
