Here are two RESO champions who were recently featured:


RESO Workgroup Meetings

Rental Subgroup | November 2, 2023
The meeting covered the topics of move-in costs and ongoing fees that renters may be required to pay, outside of their normal rent payments. The group recommended that a Move-In Costs field be created as a multi-select with several common options, as well as a field for a dollar amount to coincide with them. A multi-select Ongoing Fees field was also recommended with a similar structure of related dollar amounts field for its lookups. For the next meeting, a grid showing the lookups for RentIncludes, OwnerPays and TenantPays will be created in order to better identify inconsistencies of lookups across these related fields. | NOTES

Internet Tracking Workgroup | November 15, 2023
The meeting included a review of the Tracking Fields 2.0.10 Spreadsheet. The group was shown the recently approved field name changes for the InternetTrackingSummary fields. Actor session tracking was discussed and a vote was held for the approval of two new lookups (Sign In and Sign Out) for the EventType field. Bot vs. human Internet traffic and the possibility of adding data elements to track bot information in the future was also discussed. The privacy update covered how Proton Mail is now protecting users from UTM (Urchin Tracking Module) tracking links, information about class action lawsuits on pixel tracking and an update on privacy legislation across the U.S. | NOTES

Fast Track Subgroup | November 21, 2023
The group reviewed the comments on the first batch of suggested mappings for lookups of the top-used fields. It was decided that a second mapping option should be added when the source lookups can match more than one standard lookup and/or field. A motion was made and a vote passed to approve the mappings on the Fast Track – November 2023 – Suggested Mappings sheet, which will be loaded into the certification system for Data Dictionary 2.0 testing. The proposed amendment to the Architectural Style lookups previously approved was shown and should be reviewed prior to the next Data Dictionary Workgroup meeting. | NOTES

Data Dictionary Workgroup | November 30, 2023
The meeting included a vote for and approval of a set of architectural style lookups for the ArchitecturalStyle field, which will replace the lookups previously approved. A proposal for a field to indicate whether a property has restrictive covenants was discussed, with the group determining further research on existing implementations was needed. It was also decided that two new subgroups should be formed to establish the best way for the Data Dictionary to convey 1) smart home device/fixture information and 2) additional living unit information. Additionally, the group was informed that the Building Subgroup will hold its first meeting in January and that a proposed list of potential Building Resource fields has been posted. | NOTES
