Description
The SV-6 specifies the characteristics of data exchanges between systems. SV-6 is the physical equivalent of the logical OV-3, Operational Information Exchange Matrix, and provides detailed information on the system connections that implement the information exchanges specified in an OV-3. Human communications, such as verbal orders, are captured in the SV-1, Resource Interaction Specification, and SV-3, Resource Interaction Matrix, products only.
SV-6 describes, in a tabular format, data exchanged between systems, and the functions that produce and consume that data. SV-6 also specifies properties of these system data exchanges. MODAF does not mandate a set of standard properties, but it is typical to see periodicity, timeliness, throughput, size, information assurance and security characteristics of the exchange. In addition, the data elements, their format and media type, accuracy, units of measurement, and system data standard may also be described in the matrix.
Where a suite of SVs provides a physical specification for a logical requirement specified in a suite of OVs, the SV-6 properties should cover all the information exchange properties specified in OV-3. Similarly, it is recommended that all data elements carried by the data exchanges are shown.
It should be noted that each data element exchanged may be related to the function (from SV-4) that produces or consumes it. However, there need not be a one-to-one correlation between data elements listed in the SV-6 matrix and the data flows (inputs and outputs) that are produced or consumed in a related SV-4.
Because an SV-6 is about showing flows across system boundaries, data flows between system functions performed by the same systems may not be shown in the SV-6 matrix; there will be no corresponding system port connection.
Note: although flows of materiel, human resources and energy are permitted in SV-1 and SV-4, they are not permitted in SV-6.

Data Objects
From The MODAF System Viewpoint (SV)
p27:
The data in an SV-6 can include:
- System
- Resource interaction
- System port connector
- Data element
- Information exchange (OV-2).
Note: The term
System Data Exchangedoes not refer to one M3 element. A data exchange as described in SV-6 is a combination of a system port connector and the data elements that flow through it. Any properties shown in an SV-6 table will be properties of the system port connector.
Note: System port connector was removed at 1.2.004 - this should be Resource port connector

Comments
As it says, you cannot describe flows of anything other than data/information. It probably therefore reflects a procurer’s view rather than a designer’s view of what is needed. It is therefore not suitable as a systems engineering tool as it can only describe part of the solution - unnecessarily so given the freedoms that the 1.2.004 metamodel now allows.
