Sep 17 Meeting Notes | Oct 20 Meeting Notes
2026 Fall Conference
At the October 20 meeting, the group reviewed items approved for v2.2 and v3.0 and highlighted the new documentation site at dd.reso.org. Overviews were given of the release model, Universal Mapping Initiative (UMI) and active subgroups. Valuation-related Data Dictionary enhancements were discussed, which are a set of requests for more detailed data elements in six topics, with draft proposals coming to the workgroup soon.
Approved Votes
- Add an EventTypes multi-select field to the EntityEvent Resource to signal fraudulent listings and other events (v2.3). Its lookups are Delete Compliance, Delete Fraud and Canceled. Note that the lookup name is EntityEventTypes.

RESO received requests for more detailed data elements on six topics that may affect valuation. About 40 percent of the requested items already map to existing standards.

Data Dictionary Subgroups
UMI Workshop
The Universal Mapping Initiative (UMI) Workshop met over four 90-minute sessions to review proposed lookups for the 20 most-used fields, as surfaced by UMI analysis. Several proposed new data elements were approved, each going to the Duplication Subgroup if a duplication check is needed, then to the Fast Track Subgroup before reaching the Data Dictionary Workgroup.
Duplication | Oct 12 Meeting Notes
UMI Workshop Lookups Review: The group checked lookups proposed at the UMI Workshop for duplication with existing data elements. None were found to be duplicative, and all of them will be recommended as new lookups to the Fast Track Subgroup for review prior to going to the Data Dictionary Workgroup:
- InteriorFeatures: Living/Dining, Kitchen/Dining and Kitchen/Family Room (proposed for InteriorFeatures only, not RoomType), Jetted Tub and Steam Room
- ExteriorFeatures and InteriorFeatures: Storm Shelter and Sport Court, with definitions that explain the context in each field and refer to each other
- ConstructionMaterials: Masonry (defined as load-bearing), Wood Frame, Steel, Hardboard and Metal Frame
- Flooring: Porcelain Tile, Subfloor and Flagstone
- Roof: Steel
Fast Track | Oct 27 Meeting Notes
The group reviewed lookups proposed by the Universal Mapping Initiative (UMI) for the ConstructionMaterials, InteriorFeatures and ExteriorFeatures fields. All proposed lookups were approved for recommendation to the Data Dictionary Workgroup except Steel, None and Sport Court, which need further research or discussion. Additionally, provider outreach will be conducted for Steel, None and Water Feature. The group also reviewed several disputed machine-driven mapping suggestions and decided each could be ignored.
Global | Oct 5 Meeting Notes
The group reviewed previously recommended data elements at the request of the Data Dictionary Workgroup:
- InternetPriceDisplayYN: The group will research renaming the field around “Current” (e.g., InternetCurrentPriceDisplayYN) so it covers listings in any status. This would align it with the CurrentPrice field. The group will also research price-related text fields (e.g., PriceRemarks) for cases where the price is suppressed.
- ComplexName (proposed for the Property Resource): The group recommended definitions that set out a Subdivision > Complex > Building hierarchy:
- ComplexName: The name of the apartment block, complex or campus of buildings where the property is located. A complex is typically within a larger subdivision and may contain one or more buildings.
- Building.BuildingName: The marketing or vanity name of the building. (“Complex” is removed from the current definition.)
Interoperability
- Offer Management Demo: The 2026 Fall Conference session included a live demonstration at offers.reso.org with a listing agent and buyer’s agent exchanging an offer through an offer hub. The demo showed the payloads and fields that pass between systems.
- Proposed New Resources and Fields for Offer Management: The group built a proposal from offer data models and metadata contributed by industry participants, an Offer Management Data Flow Diagram and a mapping of Offer Management fields to the Data Dictionary. It will be finalized and posted to the Data Dictionary Workgroup for review.
Research & Development
- Smart Home / Internet of Things (IoT): At the 2026 Fall Conference, the group shared results from the RESO Smart Home/IoT Survey showing that 84 percent of respondents see a benefit in having standard data elements to communicate smart home/device information, and more than half prefer a simple structure.
- AI and General Data Governance: The group presented the Hierarchical AI Governance & Machine-Readable Usage Rights business case. It addresses the gap between human-readable license agreements and technical data delivery. A Data Governance Subgroup is gathering examples of data governance typically communicated via paper contracts. The goal is to use these examples to develop standards for communicating governance downstream with the data. Technical work will be handled by appropriate workgroups.
Transport Subgroups
Schools & Geographies | Sep 18 Meeting Notes
- Recommendations Complete: The subgroup finished its work and sent its Schools and Geographies Proposal to the Transport Workgroup.
- School Data Structure: The Transport Workgroup will decide whether the school data elements become a new Data Dictionary resource or a data shape. Either way, they will be available as a Schools collection in the Property Resource.
