The MetricsGrimoire Database Collection

The Metrics Grimoire system is composed by a set of tools designed to retrieve data from repositories related to software development. Their aim is to produce organized databases suitable for easy querying with research and industrial purposes. The data in those databases have a similar structure, to easy cross-database studies, and can be enriched with information such as linkage of the multiple identities of actors, or their affiliation. This paper presents the general structure of those databases, and a collection of up-to-date database dumps that are publicly available. They correspond to two well-known projects, Open Stack, and Eclipse, including data from source code management repositories, issue tracking systems, mailing lists, and code review systems.
