Concept	Documentation
Logical Context Element	Represents an abstract element in the given System Context on Logical Level, outside the SOI scope, interacting with the SOI.
Logical External System	A Logical External System in the Logical Domain, outside the SOI scope, interacting with the SOI. E.g., power grid, mobile network, fresh water system (in a house).
Logical Context SOI	Represents the Logical SOI in the System Context on Logical Level.
System Domain Kind	Specification for any kind of conceptual item (energy, material, information, etc.) to be exchanged on Functional or Logical Level. The System Domain Kind is agnostic to any realization on Physical Level.
LCNallowingLIE	Specifies the fact that a Logical Item Exchange is allowed on the Logical Connection.
SDKtypingLIE	Specifies the fact that a System Domain Kind defines the type of a Logical Item Exchange.
SDKtypingLIPP	Specifies the fact that a System Domain Kind defines the type of a Logical Interaction Point Property.
LIPapplyingToLET	Specifies the fact that a Logical Interaction Point applies to a Logical Element.
LIPDdefiningDetailOfLIP	Specifies the fact that a Logical Interaction Point Definition defines the exchange capabilities of a Logical Interaction Point.
Logical Interaction Point	Specifies the existence of an interaction point on Logical Level.
Logical Item Exchange	Specifies the exchange that is to take place on a connection of two interaction points on Logical Level.
LIPPspecifyingDetailOfLIPD	Specifies the fact that a Logical Interaction Point Property is a detail of a Logical Interaction Point Definition.
Logical Element	Describes a conceptual Logical Element as specification for an implementation of a system, or system element.
LIPapplyingToLCE	Specifies the fact that a Logical Interaction Point applies to a Logical Context Element.
Logical Interaction Point Definition	Specifies the exchange capabilities of an interaction point on Logical Level.
Logical Interaction Point Property	Specifies a detail of an interaction point on Logical Level.
Logical Connection	Specifies the connection of two interaction points on Logical Level. Note: Connections between logical components indicate that item flows are passed from one output of a source component to one or more inputs of target components.
Logical Environment	A Logical Environment in the Logical Domain, outside the SOI scope, interacting with the SOI. E.g., air, dirt, sun, road.
Logical User	The Logical User is the representation for a human in the Logical Domain, outside the SOI scope, interacting with the SOI.
Operational Item Exchange	Specifies the Operational Item Exchange that is to take place on an Operational Connection. Aliases: UAF::OperationalExchange
LIEimplementsOIE	specifies that this exchange in the FD implements (possibly partly) that exchange in the OD
