The United Nations Trade Data Element Directory (UNTDED, ISO 7372) is developed and published by UN/CEFACT. A UN Layout Key (UNLK) trade document has boxes which requires specific data that can be put in. The requirements for each box is recorded in a dictionary called the Trade Data Elements Directory (UNTDED, ISO 7372). The directory consists of a four- digit number to identify each data element, a data element name and a description that provides a definition of the data element. It provides an internationally accepted standard repository for the semantic of trade data elements used in international trade. The UNTDED has also been integrated into the latest standards for electronic trade documents, such as the UN/CEFACT Core Component Library (CCL) or UN/EDIFACT. Therefore the UNLK, CCL and UN/EDIFACT are intrinsically linked because of UNTDED.
