summary
Goldman Sachs open-sources Legend, a data modeling and governance platform that maps business-friendly models to disparate databases, enforces validations (data types, cardinality, enumerations), tracks lineage via model-to-model mappings, tags sensitive fields for entitlements, and exposes executable queries and auto-generated APIs. The platform runs internally with about 10,000 daily active users, integrates GUI review with GitLab and a FINOS shared instance, and aims to reduce duplication while catching schema or constraint violations before consumers break.
