-.Content
-This section describes overall, principal regulations and solution ideas that are relevant in multiple parts (= cross-cutting) of your system.
-Such concepts are often related to multiple building blocks.
-They can include many different topics, such as
-
-* models, especially domain models
-* architecture or design patterns
-* rules for using specific technology
-* principal, often technical decisions of an overarching (= cross-cutting) nature
-* implementation rules
-
-
-.Motivation
-Concepts form the basis for _conceptual integrity_ (consistency, homogeneity) of the architecture. 
-Thus, they are an important contribution to achieve inner qualities of your system.
-
-Some of these concepts cannot be assigned to individual building blocks, e.g. security or safety. 
-
-
-.Form
-The form can be varied:
-
-* concept papers with any kind of structure
-* cross-cutting model excerpts or scenarios using notations of the architecture views
-* sample implementations, especially for technical concepts
-* reference to typical usage of standard frameworks (e.g. using Hibernate for object/relational mapping)
-
-.Structure
-A potential (but not mandatory) structure for this section could be:
-
-* Domain concepts
-* User Experience concepts (UX)
-* Safety and security concepts
-* Architecture and design patterns
-* "Under-the-hood"
-* development concepts
-* operational concepts
-
-Note: it might be difficult to assign individual concepts to one specific topic
-on this list.
