• Extended cargo classification, added UN classification of dangerous goods
• Extended the definition of dangerous trajectory. A trajectory of a vessel can be considered to be dangerous for various reasons. Current version provides two subclasses of dangerous trajectories: a) those classified as dangerous because of the transferred load, b) those classified as dangerous because of the vessel's behaviour (sophisticated data analysis based on its type, speed and region of activity can support the identification of such vessels). The classes :DangerousGoodsTransport and :DangerousActivityTrajectory have been added to represent the respective sets of trajectories. The DangerousGoodsTransport class is defined as the set of (dangerous) trajectories, that have part at least one trajectory segment, that transfers some dangerous goods. This definition enables any DL reasoner to identify dangerous trajectories as soon as the associated cargo to its trajectory parts is classified.
• A trajectory part is associated with some cargo, via the :transports relation. This approach enables the description of cases where the cargo can change during the trajectory of a vessel. For example, a fishing vessel may have no cargo at departure, it may retrieve some cargo at one or more trajectory parts and move on to its destination.
• CO2 emission report is a subclass of dul:InformationEntity . A CO2 emission report is associated with a trajectory or a trajectory cluster, over the property :refersTo (inheritted from dul:Entity). The property dul:hasPart defines the set of elements of a trajectory cluster. Added a list of 40 properties for the description of CO2 emission reports.
• The MooringReport is a subclass of dul:InformationEntity . A mooring report is associated with a trajectory or a trajectory cluster, over the property :refersTo (inheritted from dul:Entity).
• Updated events module to enable the specification of a reference position (:hasReferencePosition) and time (:hasReferenceTime) for instances of :Event class. This enables the definition of events that trigger other events affecting the behaviour of vessels.
