DATASETS

MISMO offers business domain specific views of the residential standards, otherwise referred to as MISMO datasets.  These views, or datasets, tend to be focused on a particular business domain and be derivatives of the larger MISMO model.  Datasets often are presented with a data dictionary, or list of terms and related descriptions, included in the specified domain, as well as, a technical description for how to represent the dataset.  The technical description may take one or more of many possible forms including a UML Class Diagram or an XML Schema or other representation.  Additional tools and resources may also be made available with MISMO datasets to support implementation and ease of use.  For more information and to access the specifications for a particular dataset select the name of a specific dataset from the list of MISMO datasets below.
