Tailorable language for behavioral composition and configuration of software components

Many software systems suffer from missing support for behavioral (runtime) composition and configuration of software components. The concern “behavioral composition and configuration” is not treated as a first-class entity, but instead it is hard-coded in different programming styles, leading to tangled composition and configuration code that is hard to understand and maintain. We propose to embed a dynamic language with a tailorable object and class concept into the host language in which the components are written, and use the tailorable language for behavioral composition and configuration tasks. Using this approach we can separate the concerns “behavioral composition and configuration” from the rest of the software system, leading to a more reusable, understandable, and maintainable composition and configuration of software components.
