by Shishir Kakaraddi, Srinivas Raghunathan, Adam Gross and Ryan Johnston We are pleased to announce the open source release of the Fast JSON API gem geared towards Ruby on Rails applications. Introduction Fast JSONAPI is aimed at providing all the major functionality that Active Model Serializer (AMS) provides, along with an emphasis on speed and performance by meeting a benchmark requirement of b
SION, a data serialization format a little more expressive than JSON - Qiita

BSON, short for Binary JSON, is a binary-encoded serialization of JSON-like documents. Like JSON, BSON supports the embedding of documents and arrays within other documents and arrays. BSON also contains extensions that allow representation of data types that are not part of the JSON spec. For example, BSON has a Date type and a BinData type. BSON can be compared to b

JavaScript Object Notation (aka JSON) is a very popular alternative to XML for transmitting data to the web browser. Flexjson is a lightweight library for serializing and deserializing Java objects into and from JSON. What's different about Flexjson is it's control over what gets serialized allowing both deep and shallow copies of objects. Most JSON serializers mimic object serialization libraries

Serialization in java
Java provides mechanism called serialization to persists java objects in a form of ordered or sequence of bytes that includes the object’s data as well as information about the object’s type and the types of data stored in the object. So if we have serialize any object then it can be read and deserialize it using object’s type and other information so we can retrieve original object. Classes Objec
ffjson: faster JSON serialization for Golang | Paul Querna
ffjson is a project I have been hacking on for making JSON serialization faster in the Go programing language. ffjson works by generating static code for Go’s JSON serialization interfaces. Fast binary serialization frameworks like Cap’n Proto or Protobufs also use this approach of generating code. Because ffjson is serializing to JSON, it will never be as fast as some of these other tools, but it
MessagePack: Efficient, Cross Language Binary Object Serialization
Ruby Weekly is a weekly newsletter covering the latest Ruby and Rails news.

More or less, what you did there was to define a data structure; and you’ll do just fine if you only need this on a spreadsheet format. The problem is that, if you ever want to exchange this information with a database or a website, the mechanics by which these data structures are implemented on these other platforms — even if the underlying semantics are overall the same — will be dramatically di
12.1. pickle — Python object serialization — Python v2.6.4 documentation
pickle — Python object serialization¶ Source code: Lib/pickle.py The pickle module implements binary protocols for serializing and de-serializing a Python object structure. “Pickling” is the process whereby a Python object hierarchy is converted into a byte stream, and “unpickling” is the inverse operation, whereby a byte stream (from a binary file or bytes-like object) is converted back into an o
FlatBuffers: a memory efficient serialization library
Today, we are releasing FlatBuffers, a C++ serialization library that allows you to read data without unpacking or allocating additional memory, as an open source project. FlatBuffers stores serialized data in buffers in a cross-platform way, supporting format evolution that is fully forwards and backwards compatible through a schema. These buffers can be stored in files or sent across the network

These days, JSON (JavaScript Object Notation, see ECMA-404) is used in many cases where data has to be exchanged. Lots of protocols between different services use it, databases store JSON (document stores naturally, but others increasingly as well). It is popular, because it is simple, human-readable, and yet surprisingly versatile, despite its limitations. At the same time there is a plethora of
