In addition to supporting JSON for type and protocol definitions, Avro includes experimental [24] support for an alternative interface description language (IDL) syntax known as Avro IDL. Previously known as GenAvro, this format is designed to ease adoption by users familiar with more traditional IDLs and programming languages, with a syntax ...
FlatBuffers is a free software library implementing a serialization format similar to Protocol Buffers, Thrift, Apache Avro, SBE, and Cap'n Proto, primarily written by Wouter van Oortmerssen and open-sourced by Google. It supports “zero-copy” deserialization, so that accessing the serialized data does not require first copying it into a ...
Thrift is an IDL (Interface Definition Language) and binary communication protocol [2] used for defining and creating services for programming languages. [3] It was developed by Facebook. Since 2020, it is an open source project in the Apache Software Foundation.
For example, 3.14 will be serialized to 3.140 000 000 000 000 124 344 978 758 017 532 527 446 746 826 171 875. ^ XML data bindings and SOAP serialization tools provide type-safe XML serialization of programming data structures into XML. Shown are XML values that can be placed in XML elements and attributes.
Apache Thrift: from Apache, originally developed by Facebook; Avro IDL: for the Apache Avro system; ASN.1; Cap'n Proto: created by its former maintainer, avoids some of the perceived shortcomings of Protocol Buffers. Concise Data Definition Language (CDDL, RFC 8610): [1] A Notation for CBOR and JSON data structures
For example, x has the tag 1. The "Line" and "Polyline" messages, which both use Point, demonstrate how composition works in Protocol Buffers. Polyline has a repeated field, and thus Polyline behaves like a set of points (of unspecified number). This schema can subsequently be compiled for use by one or more programming languages.

The findgen function in the above example returns a one-dimensional array of floating point numbers, with values equal to a series of integers starting at 0.. Note that the operation in the second line applies in a vectorized manner to the whole 100-element array created in the first line, analogous to the way general-purpose array programming languages (such as APL, J or K) would do it.
