About Open Standards

Open standards organizations, like RESO, exist in most industries to ensure technology advancement. A well-known example is W3C, which creates the standards for the World Wide Web. The most powerful technology companies in the world agree to collaborate to build a common web that raises the technology foundations of all competitors.

This is why you can get data, apps, services, and products from many different competing companies on the same smartphone. Web-based products are built on an open standard.

In real estate, RESO’s standards are created to promote that same experience: interoperability between MLS, broker, agent, and consumer technology tools.

RESO Today

RESO’s standards and services have grown significantly over time:

Our vision is a streamlined real estate technology industry.

Our mission is to create and promote the adoption and utilization of standards that drive efficiency throughout the real estate industry.

RESO’s core values align with those of open standards organizations across the globe. Our processes and products are collaborative, business-driven, transparent, innovative, open, inclusive, and measurable. | RESO Bylaws

Our History

In 1999, the National Association of REALTORS® (NAR) joined forces with leaders in technology to explore ways to make access to MLS data easier for real estate brokers, agents, and their technology partners.

In 2002, RESO was officially created as an NAR work group and soon presented its first version of the well-documented Real Estate Transaction Standard (RETS).  RETS is a legacy means of data transfer that has been used by the real estate industry for nearly twenty years.

RESO was incorporated in November 2011 as an independent, not-for-profit trade organization.
