New 4-Country Global Data Exchange Emerges at Groundbreaking International MLS Forum Event
Five leading real estate organizations from four countries – Stellar MLS (USA), Toronto Regional Real Estate Board (TRREB, Canada), Syndicat National des Professionnels Immobiliers (SNPI) (France), Madhmoun MLS (United Arab Emirates) and San Diego MLS (USA) – announced a Memorandum of Understanding (MOU) to launch Global Data Exchange (GDX), a RESO standards-based framework for sharing public-facing listing information across borders using the RESO Web API.
The goal of GDX is to make it easier for professionals and consumers to explore international opportunities, while respecting each market’s rules, licensing and data protections.
Under the MOU, the organizations will grant controlled peer access to security-protected, standardized public listing data through RESO Web API feeds under existing publisher terms, with a clear purpose of use. Members will access a merged international feed for discovery within their existing tools, with governance provided by an oversight committee representing all founding parties. New parties may be invited into the agreement by a two-thirds vote of the founding parties.

Recent and Upcoming RESO Workgroup Meetings
Members can review workgroup agendas in the RESO Workgroup Collaboration System. | JOIN A WORKGROUP
Transport Workgroup | August 4, 2025
The group discussed the changes included in a recent policy vote. A motion was made to immediately fix a false positive in the RESO SDK that currently allows providers to implement expansions as Complex OData Types, which differs from the Data Dictionary specification. ModificationTimestamp fields were discussed, including a definition update to the existing fields and potential new timestamp fields (e.g., OriginatingSystemModificationTimestamp). Additionally, the group was directed to review and comment on the DOM Increment Proposal and PackageSale Resource Proposal from the Bulk Sale Subgroup. | NOTES
Duplication Subgroup | Thursday, August 28, 2025
The group stepped through items on the Data Dictionary Duplication sheet, which shows potential duplicate data elements in the Data Dictionary. Duplicate Types were assigned to several lookups, and recommendations for the Data Dictionary Workgroup were recorded for several lookups. | NOTES
Global Subgroup | Wednesday, September 3, 2025
The group reviewed sample data from France in the DD Global-SNPI Sample Data sheet, including fields and lookups that may be of interest. The DD Global Research-Potential New Data Elements sheet with updated usage metrics was reviewed, and group members were encouraged to review and comment on it. The need for subject matter experts (SMEs) on international data was reiterated and a plan to create a list of potential additions to the Data Dictionary was formulated. | NOTES
Research and Development Workgroup | September 4, 2025
The group continued its discussion on the potential need for fields to communicate AI permissions on listings, including whether listings can be used for training models or enhanced with AI tools. The need for examples of disaster mitigation fields was also discussed. Both of these items will be mentioned at the upcoming RESO 2025 Fall Conference, with the goal of gathering implementation examples and other feedback. An update on the Unique Licensee Identifier (ULI) from the ActivityPub Subgroup was provided and included the approval of a consensus mechanism and formula that must be met before ULIs are created. | NOTES
ActivityPub Subgroup | Friday, September 5, 2025
The ActivityPub Subgroup continued to discuss consensus mechanisms for ULI (see August Meeting) and added support for a set of mandatory participants during the confirmation process. The group also discussed the feasibility of creating a lightweight offer management specification, which it has sent to the Interoperability Workgroup for further discussion. | NOTES
Interoperability Workgroup | Wednesday, September 9, 2025
The group discussed the possibility of standardizing the exchange of Offer Management (OM) data by developing a lightweight specification using the ActivityPub protocol. The group is working on determining if sharing offer data between different OM systems is feasible and beneficial. Action items include creating a data model and to gather OM providers and SMEs to define the necessary data fields. This project could serve as a pilot for larger initiatives, such as standardizing exchanging showing data. | NOTES
Fast Track Subgroup | Tuesday, September 16, 2025
The group went over the Fast Track Suggestions Review sheet and determined that several mapping suggestions should be removed. Additionally, new suggestions for the Data Dictionary Workgroup were documented. | NOTES
Data Dictionary Workgroup | Thursday, September 18, 2025
The following proposals for new lookups were motioned for a virtual vote at the meeting: Add Study to RoomType and FireplaceFeatures, Add Survey to LotSizeSource and Add Screened Porch to ImageOf. A new field named PoolCommunityYN and changing the HorseYN field name to HorsesPermittedYN were also moved for a vote, as well as a solution for the inconsistency of the Humidifier and Dehumidifier lookups being in separate fields. Additionally, the group recommended that the definitions of the Levels, Stories and StoriesTotal be updated to better convey their typical use cases, for which a new post will be created. The group was informed of two upcoming subgroups – New Construction and Multi Family Property Type – and how to volunteer for them. | NOTES
Duplication Subgroup | Thursday, September 25, 2025
The group went through items on the Data Dictionary Duplication sheet, which shows potential duplicate data elements in the Data Dictionary. Duplicate Types were assigned to several lookups, and recommendations for the Data Dictionary Workgroup were recorded for several lookups. | NOTES
