GrimoireLab components and procedure: For these kind of studies, GrimoireLab enriched indexes would be convenient, and could be complemented, if needed, with GrimoireLab raw indexes that will be produced anyway. Using GrimoireELK for the **data** collection and enrichment ensures that the indexes will be properly stored in Elasticsearch databases. SortingHat will be used when identity merging is important for the study (as in the second example above). Kibana can be used to visualize the indexes in the enriched database, which can be useful for the exploratory study. For example, Kibana can easily show the activity of a single person in all **data** sources over time.
