OpenTravel Alliance Announces Publication of OTA Specification Version 2003A

Washington, DC, USA. June 06, 2003.

The OpenTravel Alliance (OTA) is pleased to announce the publication of the 2003A Specification that provides the travel industry and travel related services the ability to deliver new features and enhanced capabilities to travelers, through enhanced XML transactions.

The 2003A release enhances messages previously released and introduces three new message pairs, two (2) for the Hotel Industry and one (1) for the Travel Insurance Industry. Also new in 2003A, additional business scenario and instance documents have been added to the text section of the Specification. These were added to assist those companies in the implementation process.

OTA would like to thank its 120 member companies, project teams, working groups and committees that worked so diligently to provide a richer, more robust specification and further travel technology and XML development. Thanks to this effort, the OTA is one step closer to its goal of creating a common and complete XML dialect for the travel industry.
