HOPEX DoDAF2 (EN) : Overview of the MEGA Suite for DoDAF 2 Application : Creating DoDAF 2 Architectures : The Default Architecture
   
The Default Architecture
When an architecture is created, several other objects are also created. To ensure that all these objects are taken into account in reports, they must all be enclosed within the architecture scope.
Items created within the framework of a hierarchy are automatically retrieved from the starting point of the hierarchy. For example, in an organizational chart, all org-units belonging to a hierarchy are retrieved from the top level org-unit. However, many other objects are not created within the framework of hierarchies. For example, data flows between two operational nodes do not belong to any tree. In this case, the MEGA Modeling tool ensures that these objects can be safely retrieved by placing them in a MEGA library. MEGA libraries define a partition of the MEGA repository and can be seen as boundaries for given modeling projects. If a library has been set as the default library, all new objects are created within its boundary.
The MEGA Suite for DoDAF 2 functions similarly, however, for the DoDAF expert the main item is the architecture not the library. So, when creating a new architecture a new library is automatically created which will receive all new objects. When you set a default architecture, the corresponding library is automatically set as the default library and so all new created objects are contained in the library of the DoDAF architecture.
Setting the default architecture
To set an architecture as the default architecture:
1. In the DoDAF 2.0 navigation window, right-click the architecture you wish to set as the default architecture.
2. In the pop-up menu that appears, select Set as default.
A green check mark appears next to the name of the architecture concerned.
*You can also set the default architecture from the Home navigation window. In this case, right-click the library in which all data pertaining to your architecture is based and select Set as Default. The results are the same as above.
