You can use it to specify data types that are interoperable between different programming languages.\n\nExample:\n\n```\nTxOut = Addr × Value × (Datum ⊎ DataHash)? × Script?;\n```\n\nFineTypes allows you to\n\n* Define data types concisely using mathematical notation.\n* Map between data types using algebraic transformations, such as `(A + B) × C = (A × C) + (B × C)`.\n* Export type definitions to different programming languages, currently:\n    * Haskell\n* Export type definitions to different data schemas, currently\n    * OpenAPI: Schema Objects\n\nFineTypes was originally conceived to be able to specify all types in the [Cardano ledger specification][cardano-ledger] in a way that is both machine readable and visually matches the PDF document.\n\n## Contents\n\nThis repository contains\n\n* The `fine-types` Haskell package and executable.\n* The `cardano-ledger-types` package containing a reference specification of the types from the [Cardano ledger specification][cardano-ledger] in different eras (Shelley, …, Babbage).\n\n  [cardano-ledger]: https://github.com/input-output-hk/cardano-ledger/releases/latest/\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcardano-foundation%2Ffine-types","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcardano-foundation%2Ffine-types","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcardano-foundation%2Ffine-types/lists"}
