The beginning of each year is an opportunity for plotting and strategizing a successful game plan, and February is a good month to turn plans into action. Read on to see what’s cooking at RESO, starting with an update from our board chair, Rebecca Jensen.

Message From RESO Chair, Rebecca Jensen

RESO Members,

We did it. We made it past the holidays, and now it’s back to work! To that end, I look forward to serving as board chair for RESO in what is anticipated to be another year of exceptional advancements in real estate industry standards.

Two major leaps forward are already underway.

  1. RESO’s certification testing and reporting platform will launch with upwards of 400 MLSs already having passed certification. As part of RESO’s updated certification procedures, technology providers will pass testing for one or more endorsements, such as Web API Core 2.0.0 or Data Dictionary 1.7, before sending notifications to their customers for review of their unique systems. An automated email to certification applicants will provide a link to review and approve results.

       Most providers have already passed testing in your markets, and you will receive emails from your MLS vendors with your results soon. 

  1. The RESO Data Dictionary 2.0 has passed its workgroup review and is headed to the Board of Directors for ratification. It will include new resources for associations, lockboxes and much more. As the dictionary update is finalized, further details will be shared in RESO publications and within the Data Dictionary wiki.

Looking forward, we are poised to see advancements in our identifier products in 2022.

The Unique Organization Identifier (UOI) will add a single, six-digit numeric ID per organization, in addition to the current setup of multiple, nine-digit alpha-numeric IDs being given by organizational function. Potential implementation implications will be discussed with member organizations using the UOI standard.

The Unique Licensee Identifier (ULI) is moving from the discussion, definition and data pilot phase to more of a development phase in 2022, continuing a multi-year attempt to solve one of the industry’s more frustrating pain points.

Finally, our popular Working with Real Estate Data (WWRED) course’s Business Module, also known as the RED-B designation, has added updates for 2022. We are also working on a WWRED Technical Module, or RED-T designation, to complement RESO’s initial successful educational offering.

At its heart, RESO is a standards organization that creates new products to make those standards easier to support while making the industry easier to operate within.

Thank you for your membership and participation!

Rebecca Jensen
Chair, RESO 2022 Board of Directors

Data Dictionary 2.0

In the January 2022 Data Dictionary Workgroup meeting, the group officially closed the comment period on Data Dictionary 2.0, creating the first major upgrade from the 1.0 versioning that made its way up to 1.7.

Why 2.0 rather than an upgrade from 1.7 to 1.8? The workgroups focused on major changes supporting interoperability for this version, including more emphasis on standards for lookups in addition to fields and resources.

Be on the lookout for an updated wiki with new fields, new lookups, the normalization of standard relationships within resources and much more.

This is a huge step forward for organized real estate, and we are grateful to our workgroup volunteers that have contributed so much of their time to this endeavor.

Certification Update

As of January 31, 2022, RESO is no longer performing Data Dictionary 1.7 testing. We are transitioning to Data Dictionary 2.0 for the rest of 2022.

MLSs should be watching for a notification that your vendor has completed your certification testing for DD 1.7. You will be able to review your certification report and accept the results at that time.

Data validation will be part of Data Dictionary 2.0, and MLSs must include this new layer of certification testing by August 31, 2022, with an IDX Payload Endorsement.

The process of data validation will be presented in future reporting on RESO’s new certification platform. What is advertised as “available” in an MLS system does not always match the output of actual data records, and we are helping data consumers understand exactly what they should expect from a data provider.

The process that produces the data availability report also performs a host of other much-needed tasks, including:

  • schema validation on each record
  • key and modification timestamp checks
  • count queries
  • successful replication of up to 100,000 records from each Data Dictionary resource to make sure that the data matches what’s advertised and that we can use standard queries to fetch records without errors

It’s an exciting time in RESO Certification, and we appreciate your support in getting us to this point.

Working with Real Estate Data Course Updated for 2022

A curriculum that started two years ago in an airport lounge in Tucson, Arizona, was released just last year. It has blossomed into a cornerstone of real estate technology education with approximately 300 students already having enrolled in or completed the course.

RESO’s Working with Real Estate Data (WWRED) online class has been receiving rave reviews from industry insiders and newcomers alike. The WWRED Business Module is the first stage of the course and carries with it a RED-B designation for those who complete it. | READ MORE

Meeting Spotlight – Days in MLS Business Descriptions

With the completion of our Days on Market (DOM) Business Descriptions Subgroup and a new StandardDOM field in the works, we are going to move on to a subgroup to discuss a new standard Days in MLS (StandardDIM) field. There is a fair amount of background in the following links if you are not familiar with the project:

StandardDOM – Business Descriptions 
2021-10-19 DOM Call Notes 

In short, the group decided that StandardDOM was to be based on contract dates and StandardDIM would be based on system timestamps.

We are actively recruiting for the Days in MLS Business Descriptions Subgroup. Please post to the Data Dictionary Discussion Forum on the topic if you would like to join. | VIEW TOPIC
