Example

Assume that there are two organizations, each having a separate data dictionary. The first organization has a data element entry:

 <DataElement>     <Name>PersonFamilyName</Name>     <Definition>The name of a person shared with other members of their family.</Definition>  <DataElement>

and a second organization has a data dictionary with a data element with the following entry:

 <DataElement>     <Name>IndividualLastName</Name>     <Definition>The name of an individual person shared with other members of their family.</Definition>  <DataElement>

these two data elements can be considered to have the same meaning and can be marked as semantically equivalent.
