UN Core Component Library
The UN Core Component Library (CCL) is a library of business semantics in a data model, which is harmonized, audited and published by UN/CEFACT. The CCL uses Core component Technical Specifications (CCTS) to ensure consistency and interoperability. The library has contributions from many organizations including government and business and deals with Cross Border Trade for messages for Buy, Ship and Pay business processes.
The library is essentially a collection of business entities, based on core components, which can be reused in many scenarios. Business entities are the basis of documents, which are restricted by context to a specific domain. Defining the context is key as this is the basis of the restricted use of each component.
