Transport Workgroup

The Transport Workgroup is focused on defining standards that pertain to how data may be accessed by various applications. Specifically, the group is focused on the RESO Web API (application programming interface) layer between outside applications and MLS data/servers.


The initial goal and charter of this group is to define a standard for accessing MLS data via a RESTful (REpresentational State Transfer) architecture. Ultimately, this API should:

  1. Provide real-time retrieval of MLS data via standard search methods and output definitions using the already defined RESO Data Dictionary.
  2. Enable developers to more rapidly develop applications (web, mobile or other) using widely adopted technology standards and methods.
  3. Offer a standard approach that technology partners can adhere to to ensure consistency across markets while enabling technology partners to extend the standard with their own, unique approaches.

Additional information on the Web API as well as a detailed system specification can be found here.


The Transport Workgroup meets on the 1st Monday of each month at 4:00 pm ET / 1:00 pm PT. JOIN A RESO WORKGROUP!
