A node represents a computational or physical resource that hosts, manipulates, or interacts with other computational or physical resources.
Nodes are active structure elements that perform technology behavior and execute, store, and process technology objects such as artifacts.
Nodes can be interconnected by paths.
A node may be assigned to an artifact to model that the artifact is deployed on the node.
The name of a node should preferably be a noun. A node may consist of sub-nodes.
