I'm not sure to understand how what's the purpose of detectNetzgrafikJSON3rdParty() and how this is triggered, if you could provide a short video clip?

Otherwise, nice spot, we've forgotten this one

We have an data conertor at SBB which transforms internal data into the Netzgrafik. The tool will be open sourced as soon as possible, but it has still a few bugs and not yet solved stuff.

What it does: It generates all nodes and write them into a json. Then it generates all trainrun elements and its sections. But the node doesn't have the ports set. As soon as you import a json without ports, Nerzgrafik-Editor detects it and tries to import the JSON as 3rd party. During importing it recalculates the port routing and all other missing elements and updates as well trainrun categories whenever there are new ones. What you get is a complete Netzgrafik which can further edited or just used for visualisation...

Our convertor detects frequency and round-trips based on a heuristic from common timetable.

Thanks for the explanation, lgtm then :)
