View MODAF:OV-3 Operational Information Exchange Matrix View



The OV-2 Operational Node Relationship View is part of the MODAF Operational 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 Operational Viewpoint viewpoint defining document from

See MODAF Release History.


From The MODAF Operational Viewpoint p21:

The OV-3 details the operational information exchanges between nodes, as defined in the OV-2, Operational Node Relationship Diagram.

From The MODAF Operational Viewpoint p21:

Information exchanges help define the interoperability requirements associated with the operational capability of interest. Although the primary purpose of this view is to specify information exchanges, an OV-3 may also list flows of materiel, energy and human resources.

From The MODAF Operational Viewpoint p21:

The OV-3, Operational Information Exchange Matrix, identifies the information transfers that are necessary to enable the nodes to achieve a business objective. This view is initially constructed from the information contained in OV-2, Operational Node Relationship Description, and OV-5, Operational Activity Model; however, OV-3 provides a more detailed definition of the information flows between nodes.

The Operational Information Exchange Matrix details information exchanges by identifying which nodes exchange what information, with whom, why the information is necessary, and the key attributes of the associated information products. Information exchanges express the relationship across the three main M3 elements for the Operational Viewpoint (operational activities, nodes, and information flows) with a focus on the specific aspects of the information flow and the information content. OV-3 is one of a suite of operational views that address the information content of the operational architecture (the others being OV-2, Operational Node Relationship Diagram, OV-5, Operational Activity Model, and OV-7, Information Model).

The OV-3 maps information elements to the producing and consuming nodes, the needlines between them, and the activities that they support.

An information element is a piece of information that is subject to an operational process. The structure of the information element may be defined by a logical data model (see OV-7, Information Model). Information elements are carried on operation activity information flows (in OV-5) and information exchanges (in OV-2). The same information element may be used in one or more information exchanges.

An architect may specify attributes for the Information exchanges in OV-3. Typical attributes would be “timeliness”, “availability”, “protective marking”, “non-repudiation”, etc.

From The MODAF Operational Viewpoint p21:

The emphasis in this view is on the logical and operational characteristics of the information being exchanged. It is important to note that OV-3 is not intended to be an exhaustive listing of all the details contained in every information exchange of every node associated with the architecture in question. Rather, this product is intended to capture the most important aspects of selected information exchanges.

The data in an OV-3 can include:

  • Tabulation

From The MODAF Operational Viewpoint p22:

Multiple information exchanges may be bundled into one needline. In OV-3, this information is captured in tabular form, usually with the needline identifier being shown in one of the columns.

The column headings in an OV-3 matrix are not prescribed by MODAF, this allows the architect to select the most appropriate headings for a given architecture. Most OV-3 tables will at least have columns for:

Configuration History

1.2.004 adds Operational Activity and Node, materiel flow, energy flow and flow of people.

If the OV-3 can be used to describe any type of exchange the title Operational Information Exchange Matrix View is no longer consistent with the subject of the view - any type of exchange.


The data objects listed aren’t consistent with the text of the view definition - need to add materiel flow, energy flow and flow of people.

Although the extension to cover other types of flow is welcome at 1.2.004 the name is now very misleading and inconsistent with the definition of the view as it incorrectly suggests that the view only covers information exchanges.
