The floating-data relation links a Trip in progress (p:trip-in-progress) or Trip registration (p:trip-registration) to a Floating data (p:floating-data) collection. The floating-data resource contains data-points (date-time, location, speed & heading). The link can be used to add the most up-to-date information to the collection.
