View MODAF:SV-10c Resource Event-Trace Description View



The SV-10c Resource Event-Trace Description View is part of the MODAF System Viewpoint and one of the 47 MODAF views.

Version & Date

Version 1.2.004.

* =  changed at 1.2.004

+ =  new at 1.2.004

The change history is derived from the definition of each MODAF view within the The MODAF System Viewpoint viewpoint defining document from

See MODAF Release History.


From The MODAF System Viewpoint (SV) p42:

The SV-10c provides a time-ordered examination of the interactions between resources. Each event-trace diagram will have an accompanying description that defines the particular scenario or situation.

From The MODAF System Viewpoint (SV) p42:

The SV-10c provides a valuable mechanism for improving the level of detail from the initial solution design, in order to help define a sequence of interactions, and to ensure that each participating resource or resource port has the necessary information it needs, at the right time, in order to perform its assigned functionality.

From The MODAF System Viewpoint (SV) p42:

The SV10-c Resource Event/Trace Description specifies the sequence in which data elements are exchanged in context of a Resource or Resource Port. Resource event / trace descriptions are sometimes called sequence diagrams, event scenarios or timing diagrams.

The content of exchanges that connect lifelines in an SV-10c may be related, in modelling terms, with resource interactions (from, SV-1, Resource Interaction Specification, SV-3, Resource Interaction Matrix), data flows (from SV-4, Functionality Description, and SV-6, Systems Data Exchange Matrix) and data schema entities (from SV-11, Physical Schema) modelled in other views.

The interactions in SV-10c are not just limited to representing information flows. As in SV-1 and SV-4, they may also represent flows of materiel, human resources or energy.

Configuration History


Some legacy from pre 1.2.004 e.g. no longer any non-functional resources.

Makes no sense to single out a Systems Port since the lifeline associated with any Resource Port can be described according to the diagram.
