GAAR's Southwest Multiple Listing Service (SWMLS) has been awarded a Silver Certificate for its Data Dictionary Compliance– only 2 Multiple Listing Services received higher. 

The Data Dictionary serves as the real estate industry’s “Rosetta Stone” for real estate data. SWMLS, like hundreds of MLSs and other source providers, gather data, but what good is it if the data cannot be shared or understood? By complying with RESO's Data Dictionary, it ensures that the SWMLS sytem “speaks” the same language as other MLSs. It is the common standard that defines real estate data in consistent terms and data structures; a template data providers follow to format its most common fields. The SWMLS system was certified RESO compliant on 12/29/2015, meeting the NAR requirement.

Real Estate Standards Organization, or RESO, actively develops, adopts and implements open and accepted data standards and processes across all real estate transactions. It provides an environment for the development and implementation of data standards and processes. Those processes facilitate software innovation, ensure portability, eliminate redundancies and obtain maximum efficiencies for all parties participating in real estate transactions. GAAR/SWMLS' membership with RESO helps ensure our members have access to the best MLS service available.

RESO was incorporated in November 2011 as an independent, not-for-profit trade organization that was previously a section of the National Association of REALTORS®. RESO has more than 150 active members, including NAR, multiple-listing services, real estate associations, brokerages and industry technology providers.
