1. Factorize: ModelQualityStorageManager by distributing the variables: - Exclude the constants to the corresponding packages. The suggested resolution is to distribute the information to other classes. - how can I get the information for the directory and path into the quality service, if i can not use the org.fortiss.af3.project.utils.FileUtils due to dependency cycles at import? 2. Factorize "MetricKey" - Get rid of constants in this class - Rather, the data should be provided to the ModelQualityService during the registration of the metrics.
