Within the high-level architecture (HLA), what are named datums categorized as during communication?

In the context of high-level architecture (HLA), named datums are categorized as parameters during communication. Parameters serve as the means to exchange information between federates within a simulation environment. They are essentially variables that hold data values shared across different components, allowing for synchronization and coordinated operations within a distributed simulation.

This classification as parameters is crucial because it highlights how specific pieces of data can be designated for transmission, ensuring that all involved entities have access to necessary information to perform their roles effectively. By understanding this categorization, one can better grasp how data flows within HLA and how federates can interact to simulate complex scenarios accurately. This structured approach enhances the reliability and scalability of simulations.
