Public Transport GTFS

These rules add additional checks for public transportation tagging. One major part are tags in use with GTFS and PTNA (OSM-Wiki, website).

See Public Transport GTFS preset for a corresponding preset.

Notes

Really beta so far and under development. Expect false positives and lots of changes.
The tagging schema is still under heavy development and therefore the rules might change quite often.

Supported Tags

So far checks in the categories Missing tags, Conflicting tags and Value syntax for the following tags exists.

colour
duration
fee
from
gtfs:feed
gtfs:name (no page, yet)
gtfs:route_id
gtfs:shape_id
gtfs:trip_id
gtfs:trip_id:sample
~~gtfs:source_date~~ replace by gtfs:release_date
gtfs:release_date
gtfs:stop_id
interval
local_ref
network network
network:guid
network:short
opening_hours
operator
operator:guid
operator:short
railway=stop
