What is Maritime Resource Names

Maritime Resource Names (MRN) is a naming scheme that can uniquely identify any maritime resource on a global scale. By maritime resource we basically mean anything that has an identity of some kind. This could be organizations, employees, a person, a physical or a virtual object, for instance an electronic document, a buoy, a ship, a mariner, a nautical chart or an electronic service (e.g., “today’s weather report for the Oresund Strait”). Not all resources are “retrievable” in an electronic sense; For example, human beings, corporations, and buoys. However, they can still be considered a resource.

Our original paper was presented at the 17th IALA Conference. provides a more detailed explanation of the concept and a number of examples.
