The OpenTravel Alliance (OTA), the leading data standards organization for the travel industry and a member of the Linux Foundation, today announced it has joined the Overture Maps Foundation (Overture), another Linux Foundation initiative focused on building reliable and interoperable open map data for global use. By joining Overture, OTA will work with another leading consortium to resolve one of the travel industry’s most persistent challenges: standardizing location data across the highly fragmented ecosystem of travel providers, platforms, and markets by establishing open, interoperable mapping frameworks.
Overture’s open dataset already includes more than 60 million places of interest, each with standardized names, categories, and addresses. Its technical foundation includes the newly released Global Entity Reference System (GERS), a reference framework that unifies how locations are identified and integrated. By utilizing GERS, each hotel, vacation rental, airport shuttle, or train station receives a unique, persistent identifier that works across all platforms and systems. By eliminating the need to manually reconcile data from different sources, GERS streamlines how location data enters travel systems, reduces integration times from weeks to minutes, and accelerates the delivery of new location-aware services.
The travel industry has long struggled to unify data about where things are, especially across fast-changing and inconsistently named places like bus and train stations and local attractions. By integrating OpenTravel’s object models with Overture’s foundational open data and GERS framework, we aim to lay the groundwork for smarter, safer, and more connected global travel experiences. Stuart Waldron, director of the OpenTravel Alliance
From Fragmented Data to Frictionless Travel
OTA’s contributions to Overture are intended to pave the way for members to freely build upon and enrich a single source of truth for places data. While Overture does not directly handle dynamic updates such as station hours or real-time transit availability, these types of rich data can be attached to GERS IDs, enabling them to be integrated into widely used systems. These systems ultimately reach billions of consumers through applications powered by Overture members such as Tripadvisor, Uber, Esri and founders AWS, Meta, Microsoft, and TomTom. Use cases for shared data include:
- A connected travel ecosystem: GERS IDs support a seamless web of data, improving coordination across travel discovery, booking, and in-trip experiences. A hotel booking system can share precise location data with a ride-sharing app, local restaurant or tour operator using a common GERS ID.
- Richer map experiences: A stable, open base map allows developers to add travel-specific data layers. With OTA, the travel sector aligns on schemas for real-time details like hotel availability, room rate, and pet-friendly policies, allowing attribute data and other amenity updates, all linked to a GERS ID.
- Future innovations: Forward-looking applications may include lightweight open standards anchored in GERS IDs that would make AI agents for businesses discoverable. A traveler’s AI assistant could then programmatically communicate with a hotel’s AI to ask questions or make a reservation, opening a new frontier for automated travel services.
The travel industry is a prime example of a sector that relies on accurate, interoperable location data, but has been held back by a patchwork of inconsistent identifiers and siloed systems. By working with OpenTravel and its network of data providers, we’re applying Overture’s open, scalable map infrastructure to create a unified foundation to support smarter experiences, not only for travelers, but also for the AI agents and applications acting on their behalf. Marc Prioleau, executive director of the Overture Maps Foundation
In the coming months, OTA and Overture plan to align OTA’s existing location schemas and definitions to GERS IDs to enable seamless adoption. Over time, OTA’s compiler may allow updates from members to flow directly into Overture’s datasets, ensuring that the travel industry’s most authoritative data remains current, accessible, and open, without requiring OTA members to rework their internal systems.
The OpenTravel Alliance invites travel providers, booking platforms, and transit agencies to join this effort to build an open, shared map of the world’s travel infrastructure. To participate or learn more, visit opentravel.org or contact us.
