RESO Using “Primary” Instead of “Master” in Real Estate Display Names
In recent months, RESO engaged in significant discussions throughout the real estate industry regarding terms used in our technology systems like “master bedroom” and “master bathroom.”

Concerns about potentially derogatory connotations have caused some groups to push to change the “master” terms. While use of this terminology by real estate professionals has been reviewed and cleared of discriminatory violations by the U.S. Department of Housing and Urban Development, consumer and professional concerns have remained, prompting some marketplaces to use alternatives. | READ MORE


New RESO Tax Subgroup Formed

Formed from within the Data Dictionary Workgroup with freshly minted Data Dictionary Vice Chair, Kevin Tranby, in the driver’s seat, this subgroup is ready to set off on a gallant adventure into the Data Dictionary’s Property resource. Anthony Percaccio from Canada’s MPAC has discovered some pretty good alignment and showed interest in expanding on the tax piece. Combined with our aggregators and other consumers of tax data, a solid subgroup has been formed to work on expanding the tax footprint in the dictionary. | LEARN MORE

The first Tax Subgroup will meet this Wednesday, July 29 at 3:00 pm ET / 12:00 pm PT. | VIEW AGENDA


Collaborate Completely With RESO

We will always share the happenings of our workgroups within this weekly update, in posted monthly meeting “Call Notes” and on our public-facing website,, but the best details about each workgroups efforts are happening in Confluence. From an active discussions forums that determines what will be worked on in the Data Dictionary Workgroup to the business cases that are submitted to the Research & Development Workgroup to the incredible progress being made on a weekly basis in the Transport Workgroup’s Certification Subgroup, you can see behind the scenes of YOUR organization. In addition, you can find a full calendar of all RESO meetings, specifications for past Data Dictionary and Web API standards, past conference presentations, and other members. Which brings us to…

Share Your Head Shots!
RESO is a better organization when we open and transparent, which is why it would be wonderful if more of you included an image with your profile. Much like the gray silhouette of Facebook or LinkedIn or the famed Twitter egg, it’s much less enjoyable to interact with someone you can’t see. So please consider adding a photo or updating the one you created five years ago. Cameras have gotten soooo much better.

How: After logging in, select your profile in the upper right corner at Then select Picture on the left side of the screen. Upload a new image here and size as you see fit.


In future RESO Weekly Activity posts, we’ll delve into other aspects of your profile to help you get the most out of your membership.

Payloads Workgroup Meeting | July 23, 2020

Meeting Summary: The group spent the full meeting discussing two items: 1) the possibility of an “Appraisal Payload” spearheaded by Freddie Mac and 2) what would be the minimum MUST items for a “Fixed IDX Payload.” Both subjects are rich in detail and discussion, and the meeting provided a good step in the right direction for both topics. | CALL NOTES

Action Items

  • Josh Darnell has made some field rankings based on past input and will try to have something put together before the next meeting.
  • We will try to get someone from Freddie Mac or one of the appraisal groups on a future call.
  • Rick Trevino will tag the sets in the Combined DMG and TRIBUS IDX Payload Responses worksheet that he’s aware of.
  • Share Sam DeBord’s “IDX Payloads Rules 2020” document with the workgroup when it is further along.

Meeting Summary: The workgroup discussed Standard Relationships, which have been proposed to support Expandability in the Web API as well as provide a normative data shape for DD-compliant JSON Payloads.
