The Study of Interface Standard for Single Window System

Currently IMO recommendation mentioned EDI data elements only for electronic means for the clearance of ships, which is only for electronic documents. Most countries followed by IMO recommendation has been using EDI or XML document (in case of applying single window system)between user and port authority. However, because there are not existing standard communication interface, shipping company(it is declaring entity) have to submit electronic document through various transfer method by corresponding country. Even though it defines standard document for electronic means for the clearance of ships, it is not suitable to goal of IMO because of not defining interface standard. To support messaging standard, other international standard organization defined messaging specification for document exchanging. Therefore, this document proposes the interface standard between shipping company and port authority. Also it proposes the base that is able to support international interoperability integrating with single window and UNeDocs. Also it is possible to extend service as just minimal modification of legacy system because it supports to communication interface future study is that it will design the combined model with single window system and will propose designed model for electronic means for the Clearance of ships to IMO.Furthermore, when it implements Single Window Guideline for IMO member country, it shall support IMO member country to smoothly interface with other country.
