ISO 2146

ISO 2146 is an international standard that specifies basic requirements for the registration and maintenance of naming schemes and code systems used in data elements. The standard is formally titled "Societal security — Registration and maintenance of naming schemes and value types." It is applicable in various contexts, particularly where data sharing and interoperability are essential. The primary goal of ISO 2146 is to ensure that naming schemes and code systems are unambiguous, well-defined, and consistently managed over time to promote effective communication and data exchange between different systems and organizations. This management includes registering the schemes, managing changes, and ensuring availability of the definitions. The standard does not prescribe specific naming schemes or code systems, but rather provides a framework for their registration and maintenance.
