2022 RESO Fall Conference Recap

RESO 2022 Fall Conference RecapThe 2022 RESO Fall Conference, held October 25–27 in Sarasota, Florida, was another incredible gathering of the best technology minds in the real estate industry. More than 400 onsite and livestream participants enjoyed a week of presentations, networking, working on real estate’s toughest tech problems and – we cannot tell a lie – a lot of fun.

Hurricane Relief Donations

The best news of the week was that RESO’s members raised more than $90,000 for the REALTORS® Relief Foundation and Florida Realtors® Disaster Relief Fund in conjunction with Stellar MLS. Lead donors were Triangle MLS, Heartland MLS and

The money raised through these two incredible outlets have been instrumental in efficiently getting funds to the people who need them most. Thank you all for coming together for this cause.

In addition, two RESO members, TRIBUS and Solid Earth worked with many Florida MLSs to create, a listings repository of homes immediately available for rent across Florida for those who were displaced by Hurricane Ian. The site went from idea to reality within three days. Standards are not the hero of this story, but the supporters of standards stood tall in service, and RESO was cited as a great partner for helping to get this done so quickly.

RESO Today – Web API Transition Update

During opening remarks, RESO CEO Sam DeBord provided several updates on current activities, starting with welcome news about the RESO Web API. Almost all MLSs have RESO Web API services, but moving customers off of the old RETS data feeds has taken time. That said, utilization of the RESO Web API standard has skyrocketed to more than 30% of the industry’s subscribers in the last 18 months (chart 1). The trend line is most definitely up!

Nearly half of the industry’s MLSs have committed their organizations to fully converting their data customers to Web API feeds (chart 2). If your organization has begun the process, let us know at so we can recognize your leadership.

Main Stage Presentations

We were once again able to provide a varied and excellent group of presenters who shared standards-based work, oncoming trends and plenty to think about as we all continue to make the industry tick a little faster, a little cleaner and a lot more efficiently.

Dan Troup of RE/MAX presented new insights available through RESO Analytics. Industry aggregate statistics are now available in the Data Dictionary Wiki, so developers of technology and their management teams can make data-driven decisions. Are other MLSs using a particular field? Does a certain lookup already exist in another market? We are letting usage statistics lead the way for the first time in the history of the Data Dictionary. | VIEW PRESENTATION – What is RESO Analytics Telling Us?

Al McElmon from CoreLogic provided a fascinating, real-time view of metrics and opinions about RESO’s most important projects and how the Data Dictionary directly affects the industry. Attendees were given questions to answer on the spot and shown anonymized answers with a series of easy-to-read charts and graphics that reflected interesting tidbits like the fact that nearly 20% of RESO conference attendees were first-timers, that people feel as though custom fields and slow adoption are the two biggest challenges facing the Data Dictionary, and that time and money are the greatest barriers to achieving Data Dictionary adoption. | VIEW PRESENTATION – Data Dictionary’s Dramatic Effect on Your Business

A new way to replicate data from an MLS provider to a broker or broker’s vendor was demonstrated by Rick Herrera of Constellation1. Traditionally, data consumers would check constantly to look for changes on the data provider’s system. Did a new listing show up? Did one sell? Did one change? This expensive and inefficient process can become a thing of the past based on a RESO standard for push notifications and webhooks. Rick demonstrated how the MLS provider could simply push a change to the data consumer for them to know exactly when they needed to update their data without the constant checks. | VIEW PRESENTATION – Pushing vs Polling: The Future of MLS/Broker Data Distribution

Kerry Rakuson from Openn shared how standards in transaction management can drive innovation and affordability with data opportunities like audit trails and marketplace intelligence in order to break down barriers toward fair housing. | VIEW PRESENTATION – How Standards in TM Can Drive Innovation, Fair Housing and Affordability

Dave Conroy from the National Association of REALTORS® shared a fascinating look at how artificial intelligence is going to continue to impact listing photos in the near future. | VIEW PRESENTATION – What You Say is What You Get – Advanced AI’s Impact on Listing Photos

Joseph Szurgyi of MLS Grid and Turan Tekin of Zillow Group (and Co-Founder of Zillow’s Bridge Interactive data solution) delved into the promised land of one data feed to rule them all in accordance with NAR Policy Statement 8.6: One Data Source, which requires MLSs to offer their participants a single data feed in accordance with the participants’ licensed authorized uses, thus creating efficiencies for brokers who participate in an MLS and who use MLS data for multiple purposes. The data feed must be in compliance with RESO standards. | VIEW PRESENTATION – One Feed to Rule Them All: Getting It Done Right

Jessica Edgerton from LeadingRE was featured in the Broker Advisory Technology Spotlight, offering an enticing view of what the Data Dictionary of the future should look like. LeadingRE represents an international audience and wants to see the dictionary built in multiple languages, with a variety of measurement and monetary displays to truly create standards without borders. | VIEW PRESENTATION – Broker Advisory Technology Spotlight: LeadingRE

Denee Evans provided an update on Council of Multiple Listing Services (CMLS) activities over the last year and going forward, including the Champions of MLS phase of the “Value of MLS” initiative, which we highlight later in this newsletter. | VIEW PRESENTATION – CMLS Update

Kristen Carr and Donna Rauch from RPR shared practical tips on how your company can get the most out of RESO workgroups (hint: show up and participate!) in what may have been the friendliest and most team-oriented presentation of the conference. | VIEW PRESENTATION – How Your Company Can Get the Most Out of RESO Workgroups


Onsite meetings were held for all eight RESO workgroups and four subgroups. Summaries and links to more complete notes are shared in a dedicated section later in this newsletter.

Workgroup notes can always be found on each group’s page located on RESO’s workgroup collaboration system for members, Confluence. If you haven’t signed yourself into that member-only space yet, you are not getting the full benefit of your RESO membership, so check it out today!


In-person roundtables delved into discussions about:

  • transitioning to the RESO Web API
  • what should be contained with the WWRED Technical Module (RED-T)
  • smart home tech
  • how market dynamics can affect standards
  • Data Dictionary basics
  • the oncoming world of Web3
  • rental metadata for future entry into the Data Dictionary

Virtual roundtables covered:

  • the WWRED course
  • RESO Analytics
  • RESO certification from the MLS vendor perspective
  • building collaborative environments with RESO tools
  • a show and tell about cool things member organizations are working on right now

Pain Points

This year’s Pain Points session continued to work through the frank discussions that have become a staple of this open forum. The fire and brimstone of past meetings gave way to more even-keeled discourse about some commonly discussed topics and some new ones.

  • There was still a lot of interest in some form of vendor endorsement system or certification that RESO could help facilitate so that MLSs have a better idea of which vendors are on a healthy standards path.
  • There was a call for a standard for customized fields. Now that we can find them easily with RESO Analytics, it’s a matter of knowing what to do with them. Do we put them in existing Data Dictionary resources or create a Custom Resource?
  • Data consumers and MLSs alike would like a best practices guide for data updates – something reliable and understood across the industry.
  • Multi-use local fields have been a problem for some vendors. For example, a generic local field name like custom_01 will be used in multiple areas for multiple purposes and can’t be mapped correctly without lots of extra dialogue or workarounds.
  • Getting association management systems (AMS) to be more compliant with RESO standards was a noted desire.

Although the conversation was polite, it is clear that there are still many industry pain points to resolve. The industry pros in the room seemed to recognize and trust that RESO is aware of, working on and often resolving the major points that have been brought forth during the years in which conferences have closed with this open forum. | VIEW SESSION – Certification Analytics, Data Consumers Joint Subgroup and Pain Points


RESO will continue to listen to and work on what its members ask. Our mission is to create and promote the adoption and utilization of standards that drive efficiency throughout the real estate industry. The Pain Points session and the conferences themselves are important tools that we use to serve our mission. Thank you to everyone who participated. We will see you in San Antonio!

Members can view slide decks, videos and workgroup notes on the Conference Presentations page of RESO’s Confluence system. Much of this material can also be found on the RESO website.

RESO is often invited to participate in industry events, but we had just one big one in the past month because we were pretty busy with our own fall conference.

NAR NXT Ready-Set-GrowNAR NXT, The REALTOR® Experience!
RESO’s CEO Sam DeBord and three other RESO staffers were on hand at the annual National Association of REALTORS® conference and expo in Orlando, Florida. They attended governance meetings, sold the benefits of the WWRED course and its accompanying RED-B designation on the expo floor and even found time to rock out to John Cougar Mellencamp and ride brooms with Harry Potter. It was another productive annual meeting by the incredible NAR team, which persevered despite not being blessed with weather.

Industry News

CMLS: Champions of MLS
As shared at both their own CMLS2022 conference in Indianapolis in September and at the 2022 RESO Fall Conference in Sarasota, the Champions of MLS is the next phase of the “Value of MLS” initiative by the Council of Multiple Listing Services (CMLS).

The idea is to establish an increased level of engagement with federal regulators. In order to do this, CMLS has hired attorneys, Dylan Carson and Alicia Batts, to help them advocate and tell the story of the MLS at the national level with the following key points in mind:

  • Advocate and educate regulators on the consumer benefits that the MLS provides
  • Highlight the pro-competitive benefits the MLS provides 
  • Draft a white paper and economic study to share

There is more to come, and CMLS will be asking their members for support as the initiative gets off the ground.

International Update
The Canadian Real Estate Association (CREA) has decided that its national aggregated data feed ( DDF) will make all future new customer connections on the RESO Web API standard. CREA worked with RESO to develop a French-Canadian display layer for the Data Dictionary.

New member, Omni MLS, should be able to use and/or help enhance RESO’s Spanish display layer for the Data Dictionary.

DD 2.0
Data Dictionary 2.0 arrives next year, and it’s a major change for the industry, bringing broad new standardization in lookup values that agents and brokers use in MLSs.

For example, the StandardName for the DisplayName of Original List Price in the Property Resource is OriginalListPrice in our data language, not OriginalListingPrice, FirstListPrice or otherwise. Industry technology systems can display however they’d like to their customers, but our universal technology language in the background does it one way and one way only.
