RESO Data Dictionary Certification

The RESO Data Dictionary is the real estate industry’s universal language for data. It allows a wide range of systems to talk to each other in a seamless manner.

The need for the Data Dictionary arose as the real estate industry evolved from printed MLS books to a digital experience. Thousands of REALTOR® associations and MLSs adopted unique technology systems to serve their local markets. These systems often couldn’t communicate with each other.

The Data Dictionary is the solution: a standard that ensures every system can speak the same language. It defines real estate data in consistent terms and structures. The Data Dictionary is a template for building systems that are flexible, scalable, and that will more easily integrate with other tools.
