MISMO Releases Version 1.2 Commercial Reference Model


MISMO, the not-for-profit data standards subsidiary of the Mortgage Bankers Association (MBA), has released Version 1.2 Commercial Reference Model, which contains detailed specifications related to the data fields used in all commercial standards to date.

Version 1.2 augments three commercial standards that were released in February by the Environmental and PCA Reports Workgroup, which include the Property Condition Assessment Synopsis, Seismic Synopsis and revised Work Order Request and Response.

Commercial standards are based on MISMO's Logical Data Dictionary (LDD) and Reference Model, which provide the framework for development of consistent vocabulary, syntax and structures across all commercial specifications, says MISMO. Each individual standards package includes transaction-specific LDD files. The data used for electronic exchange are linked tightly with the Reference Model, and each subject-area transaction is generated from, and consistent with, the common schema.

The Version 1.2 Reference Model package includes an XML schema file illustrating data relationships and a full LDD in Microsoft Excel format with the data fields, data types and definitions used in all commercial specifications. It also hosts an extensive HTML report which details the containers, attributes, and enumerations along with diagrams and source code.
