Abstract
In the last years there has been good developments in harmonizing administrative data through the IMO Reference Data Model. Work started with Maritime Single Window but has also extend into Port operation (MSW) and just in time arrival (JIT) Likewise, there are interesting developments in harmonizing nautical and operational data, e.g. in reference routes for navigation and in new types of port information distribution. This involves cooperation between IHO and IMO as well as several international standards organizations.
