The scope, complexity and required integrity of information provided by traders in customs declarations has risen steadily, driven by factors such as
· Strict legal compliance with Customs legislation
· Information collection for other government agencies in single window initiatives
· Increased information needs for safety and security assessments
· Information sharing between customs authorities for trade facilitation and risk mitigation
The World Customs Organisation (WCO) has, in version 3 of their data model, created a structure for international standardisation, establishing a common data language and naming convention. Challenges at national level are to harmonise national terminology with WCO, and between legacy multiple systems. Tatis has therefore fully adopted the WCO data model for its TATIScms product, and uses various mechanisms to support national implementation.
· The internal model can be extended to support national data requirements
· Converters translate communication messages between external (national/system) and internal (WCOv3) language
· Rule driven validations enforce WCOv3 and national criteria for message content, data formats and enumerations (code lists)
· Rules are managed in human readable and –configurable data dictionaries
