Underneath all of the Aleph tools is Follow the Money, a data model for the most common entities and link types of anti-corruption reporting. Aleph tools browse, import or export this data.

The Follow the Money data model is designed to organise concepts which arise in money laundering and corruption investigations in a way that is useful to investigative journalists.

Follow the Money is both the name of the data model, and of a command-line tool used to generate and process data formatted using this model. Aleph is an interactive viewer on top of a search index of Follow the Money entities.

This page only provides a high-level overview of the data model. Check the reference documentation for in-depth explanations.


The data model of Follow the Money consists of so-called schemata, i.e. object types. They exist as an inheritance hierarchy, rooted in things and intervals. You can also think of these as entities and events.


Things describe most of the real-world objects represented in Aleph and Follow the Money. This includes People and Companies, Assets and Court Cases. While normally generated by the file ingestion service of the Aleph server, a large set of sub-types of Documentis creating through entity mappings.


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.
