The MISMO Residential Standards are often referred to collectively as"the MISMO Reference Model". The MISMO Reference Model consists of:
- The Logical Data Dictionary (LDD) which provides a business centric view of the model. The LDD provides standard business names, definitions, enumerations (or allowable values), formats and more in an easy to use Excel workbook format.
- The XML Schema representation of the data and relationships that support industry business processes.
- Included within the XML Schema are the SMART Doc® standards which provide formats for electronic formatting of documents.
The residential standards have evolved over time. You'll find a link to all of the current and historical approved published version in the following pages as well as a number of resources to support your implementation. If you are new to MISMO you may want to start by looking at the Version 3 General Information Guide.
