OpenFisca
What is OpenFisca?
OpenFisca is an open-source platform for modelling rules as parameterised calculations. It is well suited to thresholds, exceptions, and scenario analysis where users need explainable outcomes rather than a black-box answer.
Role in LexPons
LexPons uses an OpenFisca-compatible model for obligation calculations across frameworks such as GDPR, DORA, and sector-specific compliance logic. These transforms are generated asynchronously by the VPS backend.
