Technical specifications typically describe requirements for two (or more) systems to be able to interconnect and interoperate seamlessly.  Or, they may set forth the requirements of an infrastructure component (software, network, hardware) in order to meet the needs of the hotel industry and interoperate with various devices and systems.  Examples of technical specifications include:

• Standards for XML messaging for interfaces
• Design for hospitality-specific hardware components such as set-top boxes, connectivity panels, or remote controls for an in-room entertainment system
• Requirements for key infrastructure-level hardware/software systems, such as PBXs or network gateways

HTNG technical specifications are released to the public domain following formal ratification by the workgroup that produced them.  Pre-release specifications are available to HTNG members only.

Implementation of technical specifications is the first step towards HTNG certification.  For that process, you will also need product specifications which, along with their associated conformance statement questionnaires, state the minimum implementation of technical specifications that are required to achieve certification.  All released HTNG XML interface specifications are available for certification, typically starting a few weeks following their release.  Some non XML specifications may be available for certification in the future.

This table provides a quick reference to the latest version of each of HTNG's released technical specifications, as well as to prior versions that may be needed if you are targeting an implementation with another product that uses an earlier version.  Some referenced documents incorporate multiple specifications, in which case a "Part number" references the relevant section of the document.  In addition, many specifications have a companion zip file (containing XSDs/schemas, WSDLs, sample messages and code samples) to assist in implementation.
