Three Questions

Three Questions with G. Sax photo collageThe Three Questions interview series introduces you to real estate professionals with a hint of personality and humor. | VISIT THREE QUESTIONS

Here’s an awesome collection of professionals who were recently featured:

RESO Workgroup Meetings

Research & Development Workgroup | September 7, 2023
The group discussed the Suggested Payloads Business Case, including changing direction and leveraging the work being done by subgroups, such as the Rental Subgroup, for tagging payload fields. Business Linkage (Experience Record) and MLS Data Process Resources, previously discussed together, were split into their own separate topics, and the group discussed options for hosting, updating and means of communicating the information (spreadsheet, new resource, etc.). A potential Display Rules Resource for communicating required disclaimers, logos, fonts, etc. as requirements of data providers was also briefly discussed. All of the preceding topics are planned to be continued at the R&D meeting of the RESO Fall Conference. | Research & Development Workgroup NOTES

Transport Workgroup | September 11, 2023
The group approved creating an RCP to handle Single Feeds (RCP-035), approved the RESO Common Format proposal (RCP-025) so it can be ratified, approved the creation of an RCP to address Legacy and Deprecated Data Elements (RCP-045), and formalized naming rules for Data Dictionary resources. The group also discussed posting as well as commenting and voting on Transport discussion items in preparation for the 2024–2025 roadmap.  | Transport Workgroup NOTES

Interoperability Workgroup | September 12, 2023
There was a brief update about new metadata from Offr for use in the Offer Management Shape. There was an open discussion on Add/Edit Server Messaging, use cases for Add/Edit functionality and strategies to discuss it with a wide audience at the RESO Fall Conference. Suggestions for the Best Practices Guide were given, including visual representations of standards and workflows to be used by vendors to bring a product to market using RESO standards. | Interoperability Workgroup NOTES

Fast Track Subgroup | September 19, 2023
The group reviewed suggested mappings for PropertyType, PropertySubType, StateOrProvince and Country, which are among the most popular enumerations used. A recommendation was made to limit the Country and StateOrProvince lookup values to those defined in the ISO (global) standards and to cross-validate which Country and StateOrProvince values can be used together. | Fast Track Subgroup NOTES

Certification Analytics Subgroup | September 20, 2023
The group reviewed recommendations from the Fast Track Subgroup to start closing some enumerations, such as Country and StateOrProvince, and validating values between them in certification. PropertyType and SubType were also discussed, but there is more work to do in Fast Track in terms of mapping the existing data that’s been found in the RESO Analytics industry aggregates data set. | Certification Analytics Subgroup NOTES

Data Dictionary Workgroup | September 21, 2023
The group voted to add Heat Pump Water Heater as a new lookup under the Appliances field and also reviewed the Data Dictionary 2.0 and 2.1 Merged Spreadsheet. These items will be included in the Preflight Check feature of RESO Analytics. The group voted to go forward with correcting plural resource names to singular names for the next version release (3.0). A preview of work to implement validation between related lookup-type fields was discussed, along with the goal of enumerating the ArchitecturalStyle field. | Data Dictionary Workgroup NOTES

Rental Subgroup | September 26, 2023
The meeting covered the LeaseTerm field and how it may be improved for use in rental transactions, including the proposal for a new multi-select field called LeaseTermOptions to supplement it. The topic of move-in costs associated with rental listings was discussed, with examples of fields currently in use by the organizations of group members. Additionally, it was recommended that RESO staff research certification aggregate data to find common move-in cost-type fields used “in the wild” for consideration at the next meeting. | Rental Subgroup NOTES

Universal Property Identifier (UPI) Workgroup | September 27, 2023
The meeting included a discussion of two main ways to generate UPIs, primarily concentrating on either removing or preserving formatting, special characters, spaces and other delimiters used by governing authorities in their parcel identifiers. The group also discussed options of using a County Metadata Resource with county-level instructions on which identifier to use for UPI vs. always using the parcel number in all cases. The group would like to hold another meeting before the conference to finalize the content for the meeting at the event, and RESO staff will work with the chairs to set that up. | Universal Property Identifier (UPI) Workgroup NOTES

Commercial Real Estate (CRE) Subgroup | September 28, 2023
The group discussed the final product of the subgroup as likely being a new Data Dictionary Class for CRE and discussed the implications of a class vs. a new resource. The group continued to work on the CRE Mapping Spreadsheet and decided the best next step will be for the chairs of the CRE Subgroup and Data Dictionary Workgroup, along with RESO staff, to hold an extended meeting to map out a proposal for CRE fields to be included in the class. Additionally, it was decided that a structure of property-level and suite-level fields are likely needed. It was also recommended that amenities and size/area fields be kept at a higher level, unless the need arises to get more detailed. | Commercial Real Estate (CRE) Subgroup NOTES
