As part of quality management, it is important to ensure that Git repositories meet certain quality criteria depending on the type of the respective project. In academia, for instance, repositories of finished research projects should always comprise a readme file providing usage instructions. The range of heterogeneous resources within modern Git repositories leads to a large number of conceivable quality criteria, thus increasing the effort for validating Git repositories against the project type specific quality criteria. At the same time, there is a lack of approaches and tools supporting this validation. Hence, this paper proposes and discusses an approach based on RDF and SHACL for validating a given Git repository against a set of quality criteria defined for its intended project type. QuaRe, a working prototype implementing the approach, is provided and discussed.
