NAR Mandated RESO Data Dictionary Compliance  
As promised, Black Knight MLS (BK MLS) has developed a plan to help our MLS Customers comply with the National Association of Realtors (NAR) mandated Real Estate Standards Organization (RESO) Data Dictionary Compliance, and more important, enable all of us to benefit from the eventual adoption of the Data Dictionary and forthcoming Web API standards.

It is important to note, all MLS Customers benefit from the fundamental architecture of the BK MLS system. Each of you have completely unique data bases, and because of the broad configurability and flexibility of your MLS system, this allows us to deliver the highest degree of local data differentiation.

For the most up-to-date information and or further details regarding the BK MLS plan, please contact your System Support Manager (SSM) or email
