Jira: An Alternative Issue Tracking Dataset

Organisations use issue tracking systems (ITSs) to store their project documentation in unit-like pieces called "issues". This style of documentation encourages evolutionary refinement, as each issue can be independently: improved, commented on, linked to other issues, and progressed through the organisational workflow. Common ITSs studied include GitHub, GitLab, and Bugzilla; however, these issue trackers have been the subject of much research, while Jira, a wealth of information with additional benefits, has yet to receive such attention. Unfortunately, no public dataset of Jira repositories exists, likely due to the difficulty in finding and accessing these repositories. With this dataset paper, we release a dataset of 16 public Jiras with 1822 projects, spanning 2.7 million issues with a combined total of 32 million changes, 8 million comments, and 1 million issue links. We believe this Jira dataset will lead to many fruitful research projects investigating issue evolution, issue linking, cross-project analysis, and cross-tool analysis with the existing well-studied ITSs listed above.
