  6. Research Objectives • Assess feasibility of developing a Software Architecture Description Language that supports the phases from architecture description to implementation in order to: • Preserve the architectural integrity of the system at the implementation level • Support analysis of the concrete architecture • Support the evolution of the implementation while enforcing its architectural integrity • And directly use the implementation mechanisms of the hosting platform (C) Zawar Qayyum, European University of Brittany, 2008

  7. Approach • Provide an implementation level compiler and analysis tool for the ADL, • Incorporate some modifications in the ADL syntax in order for it to fulfill the role of a deterministic implementation language while retaining its formal ADL comportment, and • Propose formally founded platform specific extensions to the ADL in order to enable it to access reusable software components available on the implementation platform. The resulting compiler environment is called π-ADL.NET. (C) Zawar Qayyum, European University of Brittany, 2008

  8. π-ADL • Formally grounded on the π-Calculus • Support for structure and behavior • Small and simple syntax • Style definition (C) Zawar Qayyum, European University of Brittany, 2008

  9. π-ADL • Application Areas • Ambient Intelligence • Sensor-actuator Networks • Mobile Agent Systems • Human-computer Interfaces for Monitoring systems • Grid Computing Systems • Enterprise Application Integration Systems • Software Systems Targeting J2EE Platforms (C) Zawar Qayyum, European University of Brittany, 2008

  10. π-ADL • Basic units of execution: Behaviors, Abstractions (behavior templates) • Connections, Pseudo-applications • Compose, Choose and Replicate (C) Zawar Qayyum, European University of Brittany, 2008

  11. π-ADL • Primitive data types: Integer, String, Boolean, Float • Constructed Data types: tuple, view, union, any, sequence, set, bag, quote, location • Syntax for conditional statements and loops (C) Zawar Qayyum, European University of Brittany, 2008

  12. π-ADL.NET • Advantages of the .NET runtime environment: • A sophisticated Intermediate Language that can completely encode the π-ADL syntax • Large collection of reusable components, potentially accessible by π-ADL code • A major industry technology, standardized by European Computer Manufacturers Association (ECMA) (C) Zawar Qayyum, European University of Brittany, 2008
