Introduction¶

OpenCodeList is a standardised JSON format for the generic representation of code lists.

The main features are:

• Definition of generic code lists and code list collections using JSON
• Support for versioning
• Support for multilingual strings
• Support for multi-column keys
• Support for multi-column foreign keys as reference to external code lists
• OpenCodeList documents can be validated against the OpenCodeList Document Schema
• Semantically largely compatible with Code List Representation (genericode)
• Open Source

Examples¶

The following OpenCodeList example documents are available:

• ISO 3166-2 Codes for Germany
• Capitals of the German federal states

Current Status¶

OpenCodeList is still very new and is being released here in its very first version. We would greatly appreciate any feedback.
