LexPons

The Universal Language of Law

LexPons converts legal and regulatory text into structured, machine-usable representations - open, deterministic, and verifiable.

Open Standards

LexPons is built on public legal standards and reusable mappings rather than opaque compliance content. AKN4EU, Catala, OpenFisca, and policy exports stay inspectable from source to output.

Deterministic Execution

Each transform target is derived from a canonical legal representation with explicit conversion steps. JSON/XML outputs are immediate, while heavier formal models run asynchronously without breaking traceability.

FOSS Community

The project is maintained as shared infrastructure under open licences for code, standards, and documentation. Teams can self-host, contribute rule packs, and build downstream products on the same public base.
