Structure of this repository

analysis folder

This folder includes the files used for the study.

repo_information.csv file

This file collects all the summary information from the graphs. This information has been used to answer RQ1 and first part of RQ2.

The CSV file includes the following columns:

• Repository identification: index, repo, repoType and sizeUsers, which indicate the index, name, type (i.e., Organization or User/Individual) and number of users collaborating in the repository, respectively.
• Role-based distribution: developers,reporters,mergers,reviewers,commenters and cheerleaders, which count the number of users playing each role in the repository.
• Role-based activity: developer_actions,reporter_actions,merger_actions,reviewer_actions, commenter_actions and cheerleader_actions, which counts the number of actions per role in the repository.
• Role-based activity (percentages): developer_actions_perc,reporter_actions_perc,merger_actions_perc,reviewer_actions_perc,commenter_actions_perc and cheerleader_actions_perc, which shows the ratio of actions per role in the repository.

groups_information.csv file

This file collects the number of role groups identified. This information has been used to answer RQ2.

The CSV file includes the following columns:

• Repository identification: index, repo, repoType and sizeUsers, which indicates the index, name, type (i.e., Organization or User/Individual) and number of users collaborating in the repository, respectively.
• Group information: group and groupSize, which indicate the group of roles commonly found together and the number of times found in the repository.

graphs folder

This folder includes the collaboration graph for each repository.

For each repository, you will find:

• json file with the output of SourceCred (the tool we used to analyze each repository).
• pdf and png files are pictures of the graph (automatically generated).
• gml file is the graph in GML format.

GML and PNG files include the graphical representation of the graphs. Nodes have been colored according to this theme:

Color	Description
Black	Repository
Blue	Commit
Yellow	User
Green	Issue
Pink	Comment
Red	Pull Request
Orange	Review

paths folder

This folder contains the role migration paths for each repository. They are used to generate the Sankey diagrams.

For each repository, you will find a CSV file with the following columns:

• Repository identification: index, repo, repoType, which indicate the index, name, type (i.e., Organization or User/Individual) of the repository, respectively.
• Role migration path analysis: path, which indicates the role migration path found in the repository, and count, which counts the number of times such a path has been found.
