Workgroup Overview

This workgroup simplified the way distribution systems connect to each other for the sharing of rates, availability, inventory, reservations and statistics. In addition to expanding distribution opportunities for hotels, this workgroup’s output has greatly reduced the need for double entry of reservation and rate data by enabling simple, yet robust, connections of PMS, RMS, CRS, and other systems with external distribution channels (GDS, OTAs, brand websites, and other) and intermediaries. The workgroup designed a single method for implementing the highly flexible OpenTravel Alliance messages, which participating companies (and now many others) could support, enabling a near plug-and-play implementation of distribution interfaces across a wide range of distribution partners and models.

The first publicly available specification was released to the HTNG certification program in February 2007; it included reservation delivery, rate update, and availability update. Since then, the workgroup has released additional specifications that provide updates to the original release, as well as new usage profiles and WSDLs and XSDs. Some of those additions include: a reservation pull model, ARI pull, seamless shopping and booking, and statistical data extracts for revenue management systems.

Business Benefits include:

  • By developing once, vendors can achieve basic connectivity to a large number of systems in a reduced time frame
  • Eliminates manual entry of reservations and rates into the PMS
  • Enables hotels to automatically push yield controls into distribution channels in real time, without the need for custom interfaces
  • When re-branding forces adoption of a new PMS or CRS, full channel connectivity can be quickly restored
  • Provides facilities to eliminate data duplication and redundant entry of data
