| The platform modeling consists in specifying the set of nodes on which the system |
| will be deployed. |

| The platform definition contains a set of nodes. Each node represents a computation resource on a type level. |
| The specification of a platform is quite similar to the specification of a composite component: it is done by |
| means of a component (class) whose parts represent the nodes. Each of the parts is typed with a node. Since a |
| node is a class as well, the inner structure of a node can be equally modeled via parts. Thus, a hardware |
| specification can be organized hierarchically. |
| As for software components, we are in the end interested in the instances of our computation resources. An |
| operation of the Qompass context menu will create this hardware instances from the class representing the hardware |
| in a similar way as a deployment plan is created. |
| |
| Use the FCM stereotype "Target" on nodes to provide information about supported operating system and |
| available RAM and ROM (currently only the supported operation system information is evaluated). |
| A node represents a certain type of a computing resource, UML instance specifications represent a concrete |
| node instance. This concept is useful, if several identical nodes are used within a system. |
