Composable software systems have been proved to support the adaptation to new requirements thanks to their flexibility. A typical method of composable software development is to select and combine a number of patterns that address the expected quality requirements. Therefore, pattern composition has become a crucial aspect during software design. One of the shortcomings of existing work about pattern...
Metamodels evolve over time, as well as other artifacts. In most cases, this evolution is performed manually by stepwise adaptation. In most cases, metamodels are described using the MOF language. Often OCL constraints are added to metamodels in order to ensure consistency of their instances (models). However, during metamodel evolution these constraints are omitted or manually rewritten, which is...
It is argued that architecture comprehension and regression testing of a software system are the most expensive maintenance activities. This is mainly due to the fact that architectural choices are either not explicit, at every stage of the software development process, or not preserved from one stage to another. In this paper, we present an Architectural Constraint Language (ACL) as a means to formally...
