HTNG publishes a wealth of technical specifications designed to promote easy interoperability among systems used in hospitality. We also operate the only Branding and Certification program in the hotel technology industry, whereby vendor products can become certified to HTNG specifications and use the "HTNG Certified" trademark label.

This page is your guide to find the documentation you need:

• As a vendor or in-house hotel systems developer, to achieve compliance with HTNG specifications
• As a hotelier, to understand what HTNG interfaces can do for you or, if you are writing an RFP, to find out what questions you can ask your prospective vendors to qualify their commitment to adoption of HTNG interfaces.

For HTNG's certification program, one or more related Technical Specifications are grouped together into Product Specifications, identified by a Name (such as "Property Web Services") and a Version (such as "2008B"). Vendors may certify technology products as compliant with an HTNG Product Specification. This means that the product complies with requirements outlined in the Product Specification and implements one or more (but not necessarily all) of its component Technical Specifications. When a product is certified, it is allowed to display the trademark "HTNG Certified" logo, which always includes the name and version of the Product Specification.

Release Cycles and Version Names:

• HTNG Software Product Specifications (using web services) are released twice a year, in the spring and fall (see the upcoming release schedule for details). Version names consist of the year followed by the letter "A" for the spring release and "B" for the fall release, for example 2008B.
• HTNG Hardware and Infrastructure Product Specifications (related to devices, networking, etc.) will be released on an as-needed basis, and version naming conventions may differ; some will likely use the 1.0, 1.1, 2.0 type sequence.
