The HOPEX Modeling tool comes with a set of consistency rules that can be used to verify that modeled architectures are well-designed. You can also set your own rules. For further information on rules and regulations in HOPEX Modeling Suite, see the HOPEX Common Features EN manual, "Consistency Rules" paragraph.
 
In order to assist the user designing NAF architectures, a set of rules have been added that can be activated to dynamically check the relevance of certain configurations. When these rules are set, warnings are displayed in the navigation tree and/or diagrams that explain the pending issue for each architecture item and offer solutions to correct them.
The table below displays additional rules that are specific to the NAF context. All rules that are already defined can be used to check a NAF architecture.

Rule description
An operation must be defined in the context of a organizational process
Requirement
Operation
An operation is a component defining an organization process. It cannot be defined outside the scope of an organizational process.
A task must be defined in the context of system process
Requirement
Task

Capability Composition
A capability composition is a component defining a capability. It cannot be defined outside the scope of a capability.
A capability dependency must be defined in the context of a capability

Requirement
Operational Component
An operational component is a component defining an operational node. It cannot be defined outside the scope of an operational node.
A functional activity must be defined in the context of an functional process
Requirement

A functional activity is a component defining a functional process. It cannot be defined outside the scope of a functional process.
An artifact component must be defined in the context of an artifact
Requirement
Artifact Component
An artifact component is a component defining an artifact. It cannot be defined outside the scope of an artifact.
An application host must be defined in the context of an artifact
Requirement
Application Host
An application host is a component defining an artifact. It cannot be defined outside the scope of an artifact.
An architecture use must be defined in the context of a resource architecture
Requirement
Architecture Use
An architecture use is a component defining a resource architecture. It cannot be defined outside the scope of a resource architecture.
An physical asset must be defined in the context of a resource architecture
Requirement
Physical Asset
A physical asset is a component defining a resource architecture. It cannot be defined outside the scope of a resource architecture.
An human asset must be defined in the context of a resource architecture
Requirement
Human Asset
A human asset is a component defining a resource architecture. It cannot be defined outside the scope of a resource architecture.

Type of Rule
Metaclass concerned
Rule description
The use of the Entity (DM) / Data Model relationship is not recommended in the DoDAF 2 context
Recommendation
Entity (DM)
The relationship allowing the linking of an data entity to a detailing data model does not belong to the UML notation. It is not recommended to use to create data model since it will not be handle by the NAF reports.

Rule description
A participant of an organizational process should only be assigned by org-units or human assets
Requirement
Participant
It is recommended to not assign architecture items that are not org-units or human assets to the organizational process participants since the exchange compliance reports will not able to establish proper analysis.
List assigned objects that are not conformed to the rule.
A participant of an functional process should only be assigned by operational nodes or operational components
Requirement
Participant
It is recommended to assign architecture items that are not operational nodes or operational components to the functional process participants since the exchange compliance reports will not able to establish proper analysis.
List assigned objects that are not conformed to the rule.
A participant of an system process should only be assigned by artifacts, artifact components, applications, application hosts, org-units, human assets, resource architectures or architecture uses
Requirement
Participant
It is recommended to assign architecture items that are not artifacts, artifact components, applications, application hosts, org-units, human assets, resource architectures or architecture uses to the system process participants since the exchange compliance reports will not able to establish proper analysis.
List assigned objects that are not conformed to the rule.
Service Definition (Protocol)
 
Rule
Type of Rule
Metaclass concerned
Rule description
A message must be connected to one producer and one consumer role of the service definition
Requirement
Message
Development Note: Check that there is a message rule that checks that a message is not connected to two roles. This rule must be updated to include the protocol context exception.
A service point must play a provider role of a service definition.
Requirement
Service Point
A service point plays one of the roles of a service definition. This role must be a provider role so that the service point is a supporter for the exposed service.
List the wrong roles.
 
Appliance Condition: The service point is linked to any role that is not a provider role of a service definition (protocol).
A request point must be play a consumer role of a service definition
Requirement
Request Point
A request point plays one of the roles of a service definition. This role must be a consumer role so that the request point is a consumer of the requested service.
List the wrong roles.
 
Appliance Condition: The request point is linked to any role that is not a consumer role of a service definition (protocol).
A service point should be linked to a service definition role.
Suggestion
Service Point
A service point is designed to explain what service is exposed to the consumers. It is more accurately defined if a provider role of a service definition is connected.
 
Appliance Condition: The service point is not connected to a role.
A request point should be linked to a service definition role.
Suggestion
Request Point
A request point is designed to explain what service is requested by the interacting item. It is more accurately defined if a consumer role of a service definition is connected.
 
Appliance Condition: The service point is not connected to a role.

Rule description
A functional process must include only functional activities that can be based on sub-processes
Requirement
Functional Process
In order to ensure process analyses, each functional process is described by sequencing and interacting functional activities. If a sibling functional process is involved then a call to it is specified linking the appropriate activity. This enables the separation between the functional process definition and the references to other existing processes.
An organizational process must include only operations that can be based on sub-processes
Requirement
Organizational Process
In order to ensure process analyses, each organizational process is described by sequencing and interacting operations. If a sibling organizational process is involved then a call to it is specified linking the appropriate operation. This enables the separation between the organizational process definition and the references to other existing processes.
An system process must include only tasks that can be based on sub-processes
Requirement
System Process
In order to ensure process analyses, each system process is described by sequencing and interacting tasks. If a sibling system process is involved then a call to it is specified linking the appropriate task. This enables the separation between the system process definition and the references to other existing processes.
