The C2 Software Architecture Description Language (SADL)

C2 SADL (pronounced "saddle") is the language for defining architectures built according to the C2 style. C2 SADL draws its influences from the strengths and shortcomings of existing ADLs. It is currently only a prototype language and its needed support tools are under construction. C2 SADL consists of three parts:

IDN - interface definition notation, which supports specification of C2 component interfaces. See an example of a simple C2 component specified in the IDN.
ADN - architecture description notation, which allows declarative specification of C2 architectures. See an example of a simple C2 architecture specified in the ADN.
ACN - architecture construction notation, which contains features for expressing architecture changes imperatively. The ACN is mostly used for expressing dynamic architecture changes. See an example of typical dynamic changes made to a C2 architecture, specified in the ACN.
