MISMO Engineering Guidelines 0007 (Class Words and Definition Guidelines) V1.5

MISMO® announced that it is seeking member comment on several updated MISMO Engineering Guidelines (MEGs). The 30-day member comment period runs through August 13th, 2025.

Updates to this MEG include:

  • Added templates for definitions and improved formatting
  • Clarified content of Class Word “Type”
  • Combined content from MEG 0040 for a more streamlined approach
  • Changed the MEG title from “Class Words” to better reflect its content
  • Note: MEG 0040 (Data Point and Container Definition Guidelines) will be deprecated as its content is now part of MEG 0007

The MISMO 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.

MEG 0007 provides details on a list of approved class words that must make up the last component of all MISMO data point names. Class words provide consistency and clarity to data points. When the names of data points indicate the type of information they carry, practitioners can easily understand schemas, messages, and metadata using those data points.

MEG 0007 was updated to Version 1.4 with changes for unit of measure attribute names, two measure types and updates to examples that align with changes from MISMO Reference Model Version 3.6.
