We provided each ship with an indentification code. Navigocorpus contains data about vessels which were collected at different points at different dates in different sources. We found it necessary to provide users with the possibility of identifying the different information concerning the story of the same vessel. In order to do that, we had to decide whether the information concerned the same vessel or not.
Decision about the code was taken by taking into consideration different information: ship name, captain name, rig, burthen, port of register, flag, etc. One of the main problem was that information are rarely complete. Moreover, spelling are not uniform, and ship-names can change or be translated. In case of doubt, we provided two different ID.
