Construction and Composition Language (CCL)

CCL is a notation for specifying components and their assemblies. From CCL, interpretations are defined that map assemblies to predictive models of assembly behavior—that is, to reasoning frameworks.

  • CCL is an architecture description language that has been specialized to the Pin component technology.
  • Component behavior in CCL is specified in a restricted dialect of UML 2.0 statecharts.
  • CCL front end performs static semantic checks and produces an annotated abstract syntax tree (AST) for well-formed assemblies.
  • CCL currently supports a Java and C-language interface to the AST and provides an XML externalization of the AST for tool interchange.
  • Pin components and assemblies (controllers) can be automatically generated from CCL specifications.
  • Interpretations from CCL to the ComFoRT reasoning framework and Lambda-star reasoning framework have also been developed.

A complete formal semantics for CCL is currently being developed.
