  Component-based software engineering aims to reduce software development
effort by reusing established components as building blocks of complex systems.
Defining components in general-purpose programming languages restricts their
reuse to platforms supporting these languages and complicates component
composition with implementation details. The vision of model-driven engineering
is to reduce the gap between developer intention and implementation details by
lifting abstract models to primary development artifacts and systematically
transforming these into executable systems. For sufficiently complex systems
the transformation from abstract models to platform-specific implementations
requires augmentation with platform-specific components. We propose a
model-driven mechanism to transform platform-independent logical component &
connector architectures into platform-specific implementations combining model
and code libraries. This mechanism allows to postpone commitment to a specific
platform and thus increases reuse of software architectures and components.
