A Transmodel Based XML Schema for the Google Transit Feed Specification With a GTFS / Transmodel Comparison

This paper compares the Google Transit Feed Specification (GTFS) with then equivalent elements from Transmodel and then out lines a proposal to create a Transmodel based XML schema for exchanging transit stop and timetable data. The schema would be fully compatible and interoperable with both Google s GTFS and Transmodel based data sets. The main purport of this paper - a precise mapping of concepts and terminology between GTFS and Transmodel concepts has value in its own right, even without a schema being created.
