In recent years, Customs shifted its focus from EDI to an open system philosophy that would enable it to electronically exchange information by different means with all of its clients (commercial and non-commercial), partners (other government departments/agencies, both national and international) and employees. This project required the redesign of all existing client server applications to shift the existing service delivery to a Web based application, applying ebXML (electronic business using eXtensible Markup Language) as a standard message.
