A map provides a link from one terminology to another. Mapping involves "matching" between a source term and a target concept that represents the same meaning, such as between two databases that contain the data elements that are meant to be similar but are called by different names. In most cases, the relationship is between the local point of service or vendor specific terms (the “source”) and the respective term from a Reference Terminology such as SNOMED CT® or LOINC® (the “target”). A mapping process simply matches the terms or words from a local system to the appropriate concept that represents the same meanings from a Reference Terminology.
