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.

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.

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.

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

Msgpack is a library for C that implements binary serialization.

This package provides a Python wrapper library to the Apache Arrow-based Feather binary columnar serialization data frame format.

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

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

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 parsing and writing CSV data.

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

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

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.

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.

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.

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.

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.

YAML parser and emitter in C++ matching the YAML 1.2 spec.

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.

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.

Msgpack is a library for C that implements binary serialization.

Cap'n Proto is a very fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster.

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.

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.
