Describes concepts used to describe exchanged items in the SAF Conceptual Domain (Functional and Logical) and related concepts

Concept	Documentation
Conceptual Exchange Type	Specification for any type of conceptual item (energy, material, information, etc.) to be exchanged on Conceptual (Functional Architecture and Logical Architecture) Level. The Conceptual Exchange Type is agnostic to any realization on Physical Level.
typing	Specifies the fact that a Conceptual Exchange Type defines the type of a Logical Item Exchange.
typing	Specifies the fact that a Conceptual Exchange Type defines the type of a Conceptual Interaction Point Property.
beeing in	Specifies that a Conceptual Exchange Type can have certain states. Note: Of course an item is in only one distinct state at a certain time. The multiplicity means that an Item can have a set of possible states, and a state can be used to specify possible States for several Conceptual Exchange Types.
realizing	Specifies the fact that a Conceptual Exchange Type is realized by Physical Exchange Types.
System State	Describes a state (or mode) of something on system level that can have distinct states.
typing	Specifies the fact that a Conceptual Exchange Type defines the type of a Function Parameter.
General Function Usage Exchange Point	Exchange point of functional usage.
Physical Exchange Type	Specification for any kind of physical item (energy, material, information, etc.) to be exchanged on Physical Level. This is the realization of the specification made by System Domain Kinds.
Conceptual Item Exchange	Specifies the exchange that is to take place on a connection of two interaction points on Conceptual Level.
Conceptual Interaction Point Property	Specifies a detail of an interaction point on Logical Level.
Operational Exchange Type	Specifies the type of Operational Item Exchange between Operational Context Roles or Operational Processes.
deriving from	Specifies the fact that a Conceptual Exchange Type on system level is derived from an Operational Exchange Type.
