Abstract

The Palladio Bench started out as a tool for designing and analyzing the performance of component-based enterprise software systems. Over the following years, numerous extensions have been introduced to increase Palladio’s analysis capabilities. These include in particular support for additional quality attributes. With an eye on current research projects, we expect this trend to continue. This includes opening up Palladio for multiple technology domains, besides its current focus on software systems. The ever-growing number of modeling constructs, however, easily leads to users being overwhelmed by modeling complexity they do not even need in many cases. Similarly, developers of Palladio tooling struggle with consequences of weak modularization.We therefore propose a refactoring of the historically grown Palladio Component Model (PCM) into different modules that build upon each other. A core module is planned to serve as architecture description language (ADL). Modules for different quality dimensions enrich the ADL by specific modeling and analysis capabilities. This paper presents our vision of a modular PCM. Due to the early stage of the project, we focus on discussing requirements and challenges, and present initial solution ideas.
