Quarterbacking the adoption of the RESO Data Dictionary

An inside look with the Workgroup’s Chair, Rob Larson of CRMLS By Jeremy Crawford He’s at the helm of what has been hailed as real estate’s “Rosetta Stone.” Rob Larson, the Chief Information Officer of the nation’s largest Multiple Listing Service, CRMLS, chairs the RESO Data Dictionary Workgroup. The Workgroup is responsible for the real estate industry’s new and growing set of property data listing standards, which is quickly approaching the NAR mandated deadline of January 1, 2016 for Data Dictionary adoption. Larson and CRMLS are testaments to the old adage “Practice what you preach.” At CRMLS, Rob has lead a holistic Data Dictionary effort – called Data Dictionary Plus – that not only deploys the required Data Dictionary core property data fields (161), but CRMLS is converting all fields whose definition matches an entry in the Data Dictionary.

From the get-go I felt this was the right course of action because I believe in a consistent experience for my members and their clients,” Larson says. He explains, “Application vendors who use RETS are inevitably going to have their search and display mirror the fields they see coming from RETS. By taking the unrequired step of adopting the Dictionary in your MLS system, you’ll standardize the members experience as they use the variety of software options available today.” Larson points to the fact that MLS members are accessing MLS data in a lot more places than just through their MLS system; […]
