Dataset of Open-Source Software Developers Labeled by their Experience Level in the Project and their Associated Software Metrics

Developers were extracted from 17 open-source projects from GitHub. Projects were chosen that use the java<br> programming language, the Spring framework and Maven/Gradle build tools. Along with these developers, 23<br> software engineering metrics were extracted for each of them. These metrics are either calculated by analyzing<br> the source code or relative to project management metadata. Each of these developers then have been<br> manually searched for in professional social media such as LinkedIn or Twitter to be labeled with their<br> experience level in their project. Outliers have been statistically detected and manually re-assigned when<br> needed. The resulting dataset contains 703 anonymized developers qualified by their 23 project-related<br> software engineering metrics and labeled for their experience. It is suitable for studies that need to connect<br> developers’ level of experience to tangible software engineering metrics.
