NSV-6 Systems Data Exchange Matrix
NSV-6 specifies the characteristics of the system data exchanged between systems. This subview focuses on automated information exchanges (from NOV-3) that are implemented in systems. Non-automated information exchanges, such as verbal orders, are only depicted in NOV subviews.
System data exchanges express the relationship across the three basic architecture data elements of an NSV (systems, system functions, and system data flows) and focus on the specific aspects of the system data flow and the system data content. These aspects of the system data exchange can be crucial to the operational mission and are critical to understanding the potential for the non attainment of objectives and the constraints introduced by the physical aspects of the implementation.
NSV-6 relates to, and grows out of NOV-3. The operational characteristics for the NOV-3 information exchanges are replaced with the corresponding system data characteristics.
Performance attributes for the operational information exchanges are replaced by the actual system data exchange performance attributes for the automated portions of the information exchange.
The NSV-6 Report Template
The report template used to generate the NSV-6 report chapters is composed of three parameters.
• The first parameter is the Architecture to be analyzed.
• The second parameter is an optional value that is used to reduce the scope of the study. This parameter is set with interfaces described in the architecture. In this case, the NSV 6 report focuses on this set of interfaces and on the information exchanges contained in these interfaces. The HOPEX objects used to set this parameter are interactions.
• The third parameter, which is also optional is set with the exchange properties to be considered during the analysis. The objects used for these properties are of the HOPEX MetaAttribute and MetaAssociationEnd types, which are applicable to content and message flows. During the report generation, the value for the parameter is verified and for each correct value encountered, a column is added to the table that displays the value of the attribute for the content or the message flow, or the list of the objects linked to the association.
The NSV-6 Systems Data Exchange Dictionary Chapter
The Systems Data Exchange Dictionary is similar to the OV-3 Operational Information Exchange Dictionary, however, columns characterize the system properties of the exchange.
This Systems Data Exchange Dictionary chapter lists in alphabetical order all the information elements (contents) of the architecture, defined at the system level.
Each information element is then described in detail with a list of all the information exchanges in which it is involved. The source and target of the information is also included.

The NSV-6 Systems Data Exchange Matrix Chapter
This chapter identifies and displays the information elements of the architecture systems and the relevant attributes of their information exchanges. These exchanges are associated to their producer and consumer systems and tasks and to the interactions that they satisfy.
The NSV-6 Contents Linked to System Items Chapter
This chapter presents a table which lists the contents of the architecture that are linked to system items. This helps the user determine if the type of contents linked are defined according to the scope defined for this system architecture. This definition is based on the "View Type" property.
