Data Dictionary 1.3 – Production Release

The Real Estate Standards Organization (RESO) announced the release of Data Dictionary 1.3 on July 3, 2014. The Data Dictionary serves as the real estate industry’s “Rosetta Stone” for data. It defines the terms that more than 900 multiple listing services can use to ensure data consistency.

  • “Consistent data saves time and money because it makes it easier for MLSs, technology partners and other third parties to develop new, data-driven applications and services that serve Realtors® in North America”

Data Dictionary 1.3 is an important advance for the members of RESO and the industry as a whole. It has added 24 new fields for Commercial and Business Opportunity, additions and changes per the request from RESO members as well as a restructured spreadsheet to better accommodate the creation of a schema.

  • “Every MLS and listing provider is invited to implement our newest version of the Data Dictionary”
