Operational Issues, Section 12: Real Estate Transaction Standards (RETS) and RESO Standards (Policy Statement 7.90)

The integrity of data is a foundation to the orderly real estate market. The Real Estate Transaction Standards (RETS) provide a vendor neutral, secure approach to exchanging listing information between the broker and the MLS. In order to ensure that the goal of maintaining an orderly marketplace is maintained, and to further establish REALTOR® information as the trusted data source, MLS organizations owned and operated by associations of REALTORS® will implement the RESO Standards including: the RESO Data Dictionary by January 1, 2016; the RESO Web API by June 30, 2016 and will keep current by implementing new releases of RESO Standards within one (1) year from ratification. Compliance with this requirement can be demonstrated using the Real Estate Standards Organization (RESO) compliance Certification Process. Web API data access provided to participants and subscribers must have no less than the same data available via data access methods such as RETS or FTP systems, and MLS fields that exist in the RESO Data Dictionary must be delivered in conformance with the standard.
