This repository contains a definition and various implementations of Preserves, a data model with associated serialization formats in many ways comparable to JSON, XML, S-expressions, CBOR, ASN.1 BER, and so on.
Core documents
Preserves data model and serialization formats
Preserves is defined in terms of a syntax-neutral data model and semantics which all transfer syntaxes share. This allows trivial, completely automatic, perfect-fidelity conversion between syntaxes.
- Preserves specification:
- Preserves tutorial
- Quick Reference for Preserves syntax
- Canonical Form for Binary Syntax
- Syrup, a hybrid binary/human-readable syntax for the Preserves data model
Preserves schema and queries
Implementations
Implementations of the data model, plus the textual and/or binary transfer syntaxes:
- Preserves for Nim
- Preserves for Python (
pip install preserves; documentation available online) - Preserves for Racket (
raco pkg install preserves) - Preserves for Rust (crates.io package)
- Preserves for Squeak Smalltalk (
Installer ss project: 'Preserves'; install: 'Preserves') - Preserves for TypeScript and JavaScript (
yarn add @preserves/core) - (Pre-alpha) Preserves for C and C++
Implementations of the data model, plus Syrup transfer syntax:
Tools
Preserves documents
- preserves-tool, generic syntax translation and pretty-printing
Preserves Schema documents and codegen
