Current State of the Industry 15 Sponsored by the Organization for the Advancement of Structured Information Standards (OASIS) and United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT), ebXML standards provide a common method to exchange business messages, conduct trading relationships, communicate data in common terms, and define and register business processes. Collaboration and Sharing Information The elements discussed in this chapter reflect the growing movement toward a more collab- orative approach to integration at airports. The Next-Generation Air Transportation System, 2-D bar codes, adaptive compression, Recommended Practices such as CUPPS, and innovations in video analytics, intelligent sensors, and XML technologies--All of these illustrate the shift toward systems that have an open-architecture, integrated and collaborative environment. CUPPS is an especially valuable example of the integration efforts taking place. CUPPS applies a specific XML schema within a recommended practice, creating standardized processes for inte- gration. CUPPS uses information from many outside sources, including airlines, the FAA, and other agencies, and is an initiative that all parties can embrace. These developments represent a shift toward a standardized integration approach, where information is shared and integration is now more feasible than ever before.
