Product Updates
Data Dictionary
Data Elements Approved for Data Dictionary Version 2.2 (Minor)
PoolCommunityYN Field (Boolean) – Approved new field to go along with the existing PoolPrivateYN field.
Study – Approved as a new lookup under the RoomType and FireplaceFeatures fields. Study also currently exists under ImageOf.
Survey – Approved as a new lookup under the LotSizeSource field. Adding Survey under LotSizeSource brings consistency to the lookups of the measurement source fields, as it currently exists under LotDimensionsSource and RoomLengthWidthSource.
Screened Porch – Approved as a new lookup under the ImageOf field.
Data Elements and Changes Approved for Data Dictionary Version 3.0 (Major)
Move the Humidifier lookup from Appliances to OtherEquipment – Humidifier and Dehumidifier are currently in two different fields. The decision to move one of them so that they are both under OtherEquipment increases consistency in the Data Dictionary.
Change the name of the HorseYN field to HorsesPermittedYN – The new name provides more clarity to the meaning of the field.
New Projects / Focus Groups
Data Dictionary Wiki – This will be a RESO staff-led focus group to redesign the Data Dictionary Wiki. This will include selecting a new platform and wiki generator.
RESO Desktop Client – This is another RESO staff-led focus group to review, test and improve the upcoming RESO Desktop Client, which will be a desktop-based version of RESO Analytics.
Schools / Geographies Subgroup – Chaired by Dan Troup of Broker Pubic Portal and Al McElmon of Cotality, this group will work to standardize the City, PostalCode and Schools fields. Any changes from this group will be major changes for the Data Dictionary.

Research & Development Workgroup | Thursday, October 2, 2025
The workgroup focused on defining the need for AI fields in the Data Dictionary, concluding that identifying specific AI use cases and permission categories should be the next step. Discussion on Environmental Hazards and Disaster Mitigation may involve proposing new fields to communicate risk, further categorized by legal disclosure requirements vs. general property information. The group discussed ways to improve follow-up on previous Pain Points by “closing the loop” at conference sessions and documenting resolutions in resources like FAQs, Knowledge Base posts and the RESO Monthly newsletter. Additionally, a business case for officially bringing the Model Context Protocol (MCP) Server topic into the RESO ecosystem was suggested. | NOTES
Global Subgroup | Wednesday, October 8, 2025
The group reviewed the DD Global Research–Potential New Data Elements (Working) sheet, which details potential new elements, along with usage metrics derived from certification aggregate data and SNPI usage data. SNPI also provided sample metadata from France. The group identified several new data elements to pursue and will create an easy-read list of these items that will be added to as the work progresses. | NOTES
New Construction Data Elements Subgroup | Wednesday, October 15, 2025
The meeting addressed two business cases for enhancing the Data Dictionary with new construction data elements. The group will first focus on the New Construction Data Elements case, which proposes adding data elements for individual new construction properties (likely to the existing Property Resource), using submitted metadata as the primary guide. The second case, which involves data elements for whole new construction developments, will require the group to first identify specific stakeholders, goals and use cases. | NOTES
