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.

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.

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

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

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.

This package provides the FlatBuffers serialization format for Python.

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.

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.

The rencode module is a data structure serialization library, similar to bencode from the BitTorrent project. For complex, heterogeneous data structures with many small elements, r-encoding stake up significantly less space than b-encodings. This version of rencode is a complete rewrite in Cython to attempt to increase the performance over the pure Python module.

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.

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

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

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.

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.

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.

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

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.
