Semantic equivalence

For the concept in mathematical logic, see Logical equivalence.

In computer metadata, semantic equivalence is a declaration that two data elements from different vocabularies contain data that has similar meaning. There are three types of semantic equivalence statements:

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.
