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.

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 scfg, a simple configuration file format with one directive per line.

libnop is a header-only library for serializing and deserializing C++ data types without external code generators or runtime support libraries.

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 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.

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.

This package provides the FlatBuffers serialization format for Python.

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

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

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.

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.

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.

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.

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

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.

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

This package provides a C implementation of the varlink interface description protocol and a code generator.

Cereal is a header-only C++11 serialization library. Cereal takes arbitrary data types and reversibly turns them into different representations, such as compact binary encodings, XML, or JSON.

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

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