The Organized Crime and Corruption Reporting Project (OCCRP) is an investigative reporting platform formed by 40 non-profit investigative centers, scores of journalists and several major regional news organizations around the globe.

The root of the data model is Things and Intervals. You can also think of these as entities and events. Things are documents, assets, legal entites and their descendents. Intervals are business interests, court cases, sanctions and transactions (and their descendents). Intervals tend to be useful for linking two entities together, possibly over a specific time period. github
