Oh, sorry, I should have mention the gtfs:*[:*] tags and PTNA.
The gtfs tags recently went through a refinement and I am not sure if gtfs:stop_id=* + gtfs:feed=IL-MOT or gtfs:stop_id:IL-MOT=* is the better approach. For sure you can use all other appropriate GTFS tags.
Using these tags instead of source=* is definitely an approvement.
Regarding PTNA you might be interested to add Israel to it. I am sure @ToniE will happily add both, the analysis and the GTFS feed.
