Version 3 XML General Information Guide

MISMO® published the Reference Model Version 3 XML General Information Guide for Candidate Recommendation status in September 2023. Previously known as the Version 3 General Information Guide, the new edition incorporates updates required for Version 3.6 XML Reference Model.

The Version 3 XML Reference Model General Information Guide provides an overview of the progression of the MISMO standards from Version 1 through Version 3.6. MISMO recently released the final version of the Reference Model Version 3.6, which includes revisions in line with FHFA’s Uniform Mortgage Data Program, Uniform Appraisal Dataset 2, several structural maintenance update that enable the use of programmatic maintenance tools, and updates to ensure consistency across the Reference Model collection.

The guide was updated to address XML-only orientation throughout, remove extraneous security details, enhance the Version 3.5 Reference Model and Product Expansion section, add the Version 3.6 Structural maintenance section, and incorporate a new tribute section.
