This document will not discuss tools for modeling. Even though this document defines the diagram types and elements, which can be used to model technical architecture, the document does not prescribe the abstraction levels for those diagrams. The correct abstraction level for a given subject depends very much on the subject itself and its surrounding context.
This document is not supposed to be used as (self-)training material for any modeling technique. In fact, it is rather to be seen as a formal specification of standardized modeling on top of the existing specification of UML. Therefore, this document is intended to be read by people with at least basic understanding of modeling in UML. All example diagrams included in the document are to be seen as pure notational examples without being embedded in a special context.
