A Meta-model for Expressing First Class Changes
Proc. of the Third International ERCIM Symposium on Software Evolution, X, ECEASST, (2007)
Zusammenfassung
First-class changes were proven to provide useful information about the evolution history of software programs. The subjects of first-class changes are expressed on the building blocks of the program which they affect. Those building blocks are described by a meta-model. The goal of this paper is to find a proper meta-model to express first-class changes. We first establish four criteria for comparing different meta-models and form the basis of a taxonomy to classify them. Afterwards, some meta-models are evaluated with respect to those criteria. Famix is found as the best match with respect to the imposed criteria. Famix, however, still has some minor shortcomings, which can be overcome by the extensions we propose to it.
