Travelport is a company that focuses on e-commerce for travel purposes either by land or air. Users can benefit from this SDK that is available by request to create applications and increase sales. Technical requirements include Message Envelope SOAP 1.1, Message Transfer HTTP 1.1, Encryption SSL 3.0, and Web Service Description Language WSDL 1.1, an XML-based interface definition language.

When Google added transit directions to its Maps, it also created a format that allows any transit agency to be included. To date, over 400 have made their routes, schedules and fares available for the search giant using the GTFS feed format. As I lamented previously, very few of those feeds are available publicly. One developer decided to try and fix that and help transit agencies at the same time.
