(1) This appendix defines a set of graphical symbols for the graphical AADL notation. To be compliant with the graphical AADL notation you these iconic symbols must be used. These graphical symbols represent components and relationships between components in an AADL model. Graphical AADL diagrams are legal in accordance with the AADL core standard if the AADL model being presented graphically is legal and if the correct graphical symbols are used. For example, a graphical editor is not permitted to create a connection whose source and destination are not connected. Graphical presentations of AADL models are permitted to show subsets of legal AADL models. For example, property values may be entered through a property sheet or dialog box. The figures in this appendix present different views of an AADL model. These views are not prescriptive, but intended to illustrate possible views and layouts.
