To this end, we identify API references in source-code changes and aggregate such references through suitable metrics that provide different views on the API usage per developer so that certain conclusions regarding developer experience or comparisons between developers become feasible. We apply this approach in a case study for the open-source project JHotDraw.enText/Journal Article0720-8928
