Certification Update

The clock is ticking, and every REALTOR®-owned MLS needs to be in compliance with Data Dictionary 1.7 and Web API Core 1.0.2 by November 10, 2021. | LEARN MORE

Several MLS vendors are in the process of being certified. Once that is complete, MLSs can expect to hear directly from their vendor about how to apply for and receive near-immediate certification.

Some vendors are already certified and have reached out to MLSs to have them go through the final steps necessary to be listed on RESO’s website and certification map as being up to date on certification.

Policy Requirements for REALTOR® MLSs

National Association of REALTORS® (NAR) policy dictates that MLSs owned and operated by REALTOR® organizations must be in compliance with RESO’s most recently ratified standards within 12 months of RESO ratification.

A recent NAR policy update also requires REALTOR® MLSs’ Web API services to include all fields available in their RETS, FTP or other data access services. These fields must be delivered in conformance with RESO Data Dictionary standards.

RESO Hits the Road with Refreshed Industry Message: RETS Will End

RESO participated in the National Association of REALTORS® Innovation, Opportunity & Investment (iOi) Summit in August, will be participating in the Council of Multiple Listing Services (CMLS) conference in September and will be hosting its own conference in October.

At iOi, RESO CEO Sam DeBord was given an opportunity to talk about the importance of third-party verification for the adherence to data standards and how important that is to new technology development. It’s difficult to build modern tech on broken or outdated systems.

To that end, while on stage, Sam dropped the hammer on the impending switch from RETS to Web API for data transfer, but it won’t be heavy handed. In the coming months, RESO will introduce a T-RETS countdown to the extinction of an industry dinosaur. We will highlight the organizations that have already embraced the Web API comet and those that are well ahead of the pack.

The RESO Web API’s time has arrived, and the next era of real estate data transfer will be a Paradise Age, not an Ice Age.

RESO’s upcoming certification reports were also teased at iOi. You can see some initial screenshots of these reports on the Certification section of RESO’s website (subject to change).

Keep your eyes open to more news from RESO at other conferences or consider inviting us to your conference. Where there is real estate, there is RESO.

Workgroup Spotlight – Showing Subgroup

The showing space has seen plenty of new and evolving players this year. In light of the additional companies offering showing services, there is a need for the Data Dictionary to account for different systems being able to talk data at each other in a seamless way to accommodate customer needs. Enter a new Data Dictionary Workgroup spinoff called the Showing Subgroup.

The temporary group has been tasked to create a common terminology to be added to the Data Dictionary that can be used between systems. 

This is not about implementations or the data language used between an MLS and a showing provider. This is about unique showing ecosystems talking to each other.

There have been three meetings so far, and the meetings are drawing quite a crowd. More than 60 people have participated in at least one meeting. Attendance is great, metadata is better, dictionary definitions are best!

RESO Workgroup Meetings

Data Consumers Subgroup | July 19, 2021
In the first Data Consumers Subgroup meeting, technology vendors, MLS vendors, MLS representatives and other real estate industry professionals gathered to go over “pain points” of working with real estate data in this data transport-related offshoot of RESO’s popular biannual conference Pain Points session. The goal is to create more frequent touch points and more meaningful action plans to erase pain in an orderly and measurable fashion. | VIEW CALL NOTES

Days on Market Business Descriptions Subgroup | August 2, 2021
The group reviewed the Days on Market (DOM) formula that has been shared in the StandardDOM – Business Descriptions Discussion Forum and went over listing status progression scenarios to determine proper interpretations of DOM. Consensus treatment of DOM was found for two common scenarios – Purchase Contract failed to close and Purchase Contract closed escrow – and then the group agreed that any status being On Market or Off Market would be defined by the Data Dictionary definitions of the statuses. | VIEW CALL NOTES

Showing Subgroup | August 4, 2021
In the inaugural Showing Subgroup meeting, the group discussed industry goals for revisiting showings in the Data Dictionary, critical components of scheduling showings, what’s missing from the Showing resource and a roadmap for achieving goals. | VIEW CALL NOTES

Research & Development Workgroup | August 5, 2021
The group discussed rules around the display of licensee contact information, the ongoing collapsing of organizations down from two IDs to one ID in the transition from the sunsetting OUID to Unique Organization Identifier (UOI), the ongoing advancement of the Unique Licensee Identifier (ULI), and a keep-alive mechanism for a session and finding a standard to service providers to extend sessions. | VIEW CALL NOTES

Unique Licensee Identifier (ULI) Subgroup | August 6, 2021
There was a review of user stories, followed by a presentation of some initial UI designs. The group reviewed current project goals, which are to develop a UI for the prototype and deploy it so ULI Pilot participants can test with real data and help refine the search methodology; these results will ultimately become part of a case study and white paper on how to search and deduplicate licensee information. | VIEW CALL NOTES

Board Liaison Committee | August 6, 2021
This meeting is held once per month in order to give workgroup chairs an opportunity to converse about their top agenda items, request help from each other and provide summary reports to the RESO Board of Directors. The reports are collected and shared as part of the meeting’s official call notes. | VIEW CALL NOTES

Transport Workgroup | August 9, 2021
The workgroup continued discussion of the Field resource, and then talked about whether to tackle the Add/Edit or Expand endorsement next, with the group preferring the former at this point. Data Dictionary JSON Payloads from any API were revisited, a topic which the Transport group had previously approved proposals for, which now have two implementations with providers seeking certification. | VIEW CALL NOTES

Interoperability Workgroup | August 10, 2021
The workgroup discussed the addition of a Transaction Management Contacts resource to the Data Dictionary. Terms and data shape are still being discussed, but the group is working toward a final vote next month to present to the Data Dictionary Workgroup. Once the group moves Transaction Management forward, it may be looking more closely at documents, particularly signatures. Subject matter experts are actively being engaged not only for this topic but for other possible pain points of cross-platform interoperability. | VIEW CALL NOTES

Showing Subgroup | August 11, 2021
This second meeting of the Showing Subgroup continued to define the scope of these meetings, which is not implementation strategies but determination of a common terminology for inclusion in the Data Dictionary that is based on existing metadata of organizations that are currently active in the showing space. Between this meeting and the next subgroup meeting on September 1, the group is collecting metadata for further discussion and comparison. | VIEW CALL NOTES

UPI Registry Subgroup | August 11, 2021
The group continues to work on how to market the UPI and how to build a UPI Registry. Work will be done to shine a more focused light on what the UPI is, how to use it and why it is a great tool. Meanwhile, a new UPI Service Container has been built that is actively in search of testing, usage and feedback. | VIEW CALL NOTES

Internet Tracking Workgroup | August 18, 2021
The workgroup talked about how Redfin and other sites implement tracking, using artificial intelligence (AI) or otherwise. This was followed up by a discussion about how single sign-on (SSO) products provide tracking information and possible ways it could be approved upon for the benefit of stakeholders. Lastly, current events about privacy were discussed. | VIEW CALL NOTES

Certification Subgroup | August 19, 2021
The workgroup discussed the specification and testing rules for the Expand endorsement as well as the migration of Transport and Certification specifications to GitHub. | VIEW CALL NOTES

Distributed Ledger Workgroup | August 24, 2021
The workgroup discussed the concept of containers to validate Universal Property Identifiers (UPIs), its features, how to increase their adoption and the best approach to document the standard. | VIEW CALL NOTES

Universal Property Identifier (UPI) | August 25, 2021
The group decided to sunset the separate UPI Registry Subgroup meeting, and then discussed UPI field population, a Data Dictionary change from PUID to UPI and what the immediate focus should be to promote UPI adoption. | VIEW CALL NOTES

Showing Subgroup | September 1, 2021
The group continued to define the goal of creating a common terminology for showing service to showing service interoperability to be included in the Data Dictionary. Submitted metadata was discussed and compared for commonality but more showing service metadata would help develop what is beginning to look like a unique Data Dictionary resource. | VIEW CALL NOTES

Research & Development Workgroup | September 2, 2021
The group discussed the priority and future of the IdP Keep-Alive Interaction along with pivoting the Licensee Display Rules to include social media links. There was also a status update on the Unique Organization Identifier (UOI) merging project and a discussion about which topics would be discussed during the RESO Retreat fall conference. | VIEW CALL NOTES
