This repository contains a proposal and various implementations of Preserves, a new data model and serialization format in many ways comparable to JSON, XML, S-expressions, CBOR, ASN.1 BER, and so on.

WARNING Everything in this repository is experimental and in flux! The design of Preserves is not finalised and may change drastically. Please offer any feedback you may have with this in mind.

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 tutorial
Preserves specification, including semantics, data model, textual syntax, and compact binary 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)
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)

Implementations of the data model, plus Syrup transfer syntax:
