Location Communication between (web based) Servers
Data communication in XML, within- and between the gazetteer part of the system (determining origin and destination of your trip) and the trip planning part Uses co-ordinates (WGS'84) as well as public standard identifiers (IATA airport codes, OVR busstop codes (NL), Railtrack station IDs (UK), etc - all valid locations in the context of Public Transport ) Final Thoughts: Now one Gazetteer Processor... but anyone can create valid XML locations for input to the system. POI "owners" might be interested to post their locations to attract the public Now one User Interface, but adding a WAP server would be peanuts
