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

PersonFamilyName
The name of a person shared with other members of their family.

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

IndividualLastName
The name of an individual person shared with other members of their family.

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