Cross-Component Issue Metamodel and Modelling Language

Software systems are often built out of distributed components developed by independent teams. As a result, issues of these components, such as bugs or feature requests, are typically managed in separate, isolated issue management systems. As a result, it is hard to keep an overview of issues affecting issues of other components. Managing issues in a component-specific scope comes with significant problems in the development process since managing such cross-component issues is error-prone and time-consuming. Therefore, the cross-component issue management system Gropius was developed in previous work, which is a tool for integrated cross-component issue management that acts as a wrapper across the independent components' issue management systems. This paper introduces the underlying metamodel of Gropius in detail and presents the graphical modelling language implemented by Gropius.
