Valijson is a header-only JSON Schema validation library for C++11. It provides a simple validation API that allows loading JSON Schemas, and validate documents loaded by one of several supported parser libraries.

LibYAML is a YAML 1.1 parser and emitter written in C.

This package provides a C version of the reader, parser and emitter for ruamel.yaml derived from libyaml.

Msgpack is a library for C that implements binary serialization.

Python-cbor provides an implementation of the Concise Binary Object Representation (CBOR). CBOR is comparable to JSON, has a superset of JSON's ability, but serializes to a binary format which is smaller and faster to generate and parse. The two primary functions are cbor.loads and cbor.dumps.

Msgpack is a library for C/C++ that implements binary serialization. This is the legacy version that predates the split into C and C++ specific packages.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

This package provides YAML parser/emitter that supports roundtrip preservation of comments, seq/map flow style, and map key order. It is a derivative of Kirill Simonov’s PyYAML 3.11. It supports YAML 1.2 and has round-trip loaders and dumpers. It supports comments. Block style and key ordering are kept, so you can diff the source.

This package provides a C library for parsing and writing CSV data.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

This package provides a C library for to parse scfg, a simple configuration file format with one directive per line.

LibCYAML is a C library written in ISO C11 for reading and writing structured YAML documents. The fundamental idea behind CYAML is to allow applications to construct schemas which describe both the permissible structure of the YAML documents to read/write, and the C data structure(s) in which the loaded data is arranged in memory.

FlatBuffers is a cross-platform serialization library for C++, C#, C, Go, Java, JavaScript, PHP, and Python. It was originally created for game development and other performance-critical applications.

msgspec is a fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML. It includes the following features:

• High performance encoders/decoders for common protocols.

• Support for a wide variety of Python types.

• Zero-cost schema validation using familiar Python type annotations.

• A speedy Struct type for representing structured data.

This package provides a JSON parser written in shell, compatible with ash, Bash, Dash and Zsh. Pipe JSON to it, and it traverses the JSON objects and prints out the path to the current object (as a JSON array) and then the object, without whitespace.

JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

Libfyaml is a YAML parser and emitter, supporting the latest YAML spec and passing the full YAML testsuite. It is designed to be very efficient, avoiding copies of data, and has no artificial limits like the 1024 character limit for implicit keys.

Msgpack is a library for C++ that implements binary serialization.

ckdl is a C library for parsing and emitting KDL. This package also provides kdlpp, a C++20 wrapper around ckdl.

Apache Avro is a data serialization system. Avro provides:

1. Rich data structures;

2. a compact, fast, binary data format;

3. a container file, to store persistent data;

4. remote procedure call (RPC); and

5. simple integration with dynamic languages.

Code generation is not required to read or write data files nor to use or implement RPC protocols.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

This package provides the C implementation of the varlink interface description protocol and its associated command line tool

StrictYAML is a type-safe YAML parser that parses and validates a restricted subset of the YAML specification.
