Overview over concepts used to describe contexts.

Concept	Documentation
System Of Interest	An abstract element representing a SOI. Base class for specific kinds of SOIs.
System Context	Specifies the fact that a context for a System of Interest is defined.
Logical Context Element	Represents an abstract element in the given System Context on Logical Level, outside the SOI scope, interacting with the SOI.
Logical System Context	Specifies the fact that a System Context for a System of Interest is defined on Logical Level.
Logical Context SOI	Represents the Logical SOI in the System Context on Logical Level.
Physical System Context	Specifies the fact that a context for a System of Interest is defined on Physical Level.
Physical SOI	Represents the Physical SOI on Physical Level.
Physical Context Element	Abstract element of a System Context on Physical Level, outside the SOI scope, interacting with the SOI.
Operational Context	An Operational Context is representing a separate Usage Scenario with a specific configuration of Operational Performers, these are interacting in the Scenario exhibiting a specific identified Operational Capability. One or more Operational Contexts meaningful for the Operational Domain are to be identified. Aliases: UAF::HighLevelOperationalConcept
LCNallowingLIE	Specifies the fact that a Logical Item Exchange is allowed on the Logical Connection.
LIPapplyingToLET	Specifies the fact that a Logical Interaction Point applies to a Logical Element.
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.
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 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.
Operational Performer	An Operational Performer is an element of the Operational Context that is capable to perform Operational Process Activities contributing to a specific identified Operational Capability. An Operational Performer may be any kind of organization, person, or even a system playing a role in one or more Operational Contexts. Aliases: UAF::OperationalPerformer
System Context Element	An abstract element representing a System Context Element. Base class for specific kinds of Context Elements.
Operational Context Role	An Operational Context Role represents a participant in an Operational context. It is interacting with other roles of the given Operational Context. Specific characteristics and features or, in case of persons or organizational units, knowledge and skills are assigned to a role necessary for the execution of the performed Operational Processes.
General Context	Specifies a General Context.
General Context Element	Specifies a General Context Element.
General Context Element Role	Specifies the fact that a General Context Element exists in a given General Context.
System Context Element Role	Specifies the fact that a System Context Element exists in a given System Context.
System SOI Role	Specifies the fact that a System SOI exists in a given System Context.
Logical Context Element Role	Specifies the fact that a Logical Context Element exists in a given Logical System Context.
Logical SOI Role	Specifies the fact that a Logical Context SOI exists in a given Logical System Context.
Physical Context Element Role	Specifies the fact that a Physical Context Element exists in a given Physical System Context.
Physical SOI Role	Specifies the fact that a Physical SOI exists in a given Physical System Context.
System Context Role	General role of a Logical System Context.
