Abstract
In 2019, the International Maritime Organization (IMO) made it mandatory to support the electronic clearance of ships entering foreign ports. In preparation, the IMO Facilitation Committee started to develop a reference data model to harmonise the most important standards for ship clearance. The first version was published in 2020. The model is already extending into other areas of ship-port data exchanges and it is now increasingly seen as a tool to coordinate development of new electronic data exchange standards for ship operations. The lack of such coordination has, up until now, been a significant problem—much better coordination is essential in the relatively small and highly international market that shipping represents.
