MISMO Engineering Guidelines

MISMO has developed a series of guidelines to govern the development of MISMO standards and collateral work products. The MISMO Engineering Guidelines, or MEGs, ensure that MISMO work products adhere to all applicable technology standards, are produced in a consistent fashion, and meet the needs of the mortgage industry.

MEGs apply to the following work products:  

  • Logical Data Model
  • Logical Data Dictionary
  • Reference XML Schema
  • OpenAPI Representations (forthcoming)
  • Decision Models
  • Entity-Relationship Model
  • SMART Doc® Specifications

MISMO Members can access all of the MEGS in one comprehensive folder in the Resource Library on MISMO Connect.   

The MISMO Architecture Workgroup (AWG) is responsible for developing the MEGs. MISMO members can post questions/comments on the MEGs to the AWG community site on MISMO Connect. Non-Members can send questions/comments to info@mismo.org
