1. Active Components a Software Product Line Infrastructure Bas Geertsema Slinger Jansen Information and Computing Sciences University Utrecht VARI-ARCH Workshop August 23, 2010

2. Introduction app for healthcare organisations app for insurance vendors Software Product Population Software Product Family

3. How to.. Define the variant ? (design) Reuse the design (with small adaptations)?

4. Question Which software product line infrastructure supports software product populations and step-wise refinements of software products? Case: A Dutch ISV developing for a wide range of industries using an application generator

5. Active Components Very adaptive, self-describing components Active because invoked during derivation (empowered!) Domain-specific models to express variability Propagate variability using transformations (MDE)

6. Applications Applications consist of: component composition design in domain-specific models Applications are incrementally defined (pos. variability)

7. Derivation

8. Variability in models Domain-specific models Variability specified close to problem domain Flexible (graph) Orthogonal variability models Ease of use (features) Standardized in SPL Composition of components Component model

9. Stakeholders SPL developer Orchestrate variability mechanisms Develop integration framework of SPL Component developer Define domain-specific meta-models Propagate variability in component Application developer Decision maker or modeler

10. Architectural Views Architecture can be expressed in a DSL architectural meta-models defined in the SPL Transformation of architectural models/views based on (variability) models upon derivation

11. Discussion
