TRAVIC vs. TRAVIC, data format for real time data (any standards ?)

[coffeepotprotocol]

Hi all,
thanks for the list here https://github.com/MobilityData/awesome-transit#visualizations. In "visualizations", there's a link to https://mobility.portal.geops.io for TRAVIC. There's another TRAVIC here (including buses with real time data) https://travic.app, documentation https://ad-publications.informatik.uni-freiburg.de/GIS_travicdemo_BBS_2014. Means the latter is missing in the overview.

I'm currently in contact with NVBW (MobiData BW) to check why the real time data for Reutlingen (RSV buses) doesn't work in TRAVIC and https://open-store.io/app/fahrplan2.luksus. It works for https://github.com/grote/Transportr and https://gitlab.com/oeffi/oeffi, though (I assume as they both use https://gitlab.com/oeffi/public-transport-enabler, which might include a fix ?). Real time data works for the city of Tübingen with both TRAVIC and Fahrplan. Any hint what to look for first ?
