jackson-core
Core part of Jackson that defines Streaming API
This project contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format. The core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain the word 'json' are JSON-specific. This package is the base on which Jackson's data-binding package builds on. It is licensed under Apache License 2.0. Alternate data format implementations (like Smile (binary JSON), XML, CSV, Protobuf, and CBOR) also build on this base package, implementing the core interfaces, and making it possible to use standard data-binding packages regardless of underlying data format. -

JSON Schema Validator
A fast Java JSON schema validator that supports draft V4, V6, V7, V201
This is a Java implementation of the JSON Schema Core Draft v4, v6, v7, v2019-09 and v2020-12(partial) specification for JSON schema validation. In addition, it also works for OpenAPI 3.0 request/response validation with some configuration flags. For users who want to collect information from a JSON node based on the schema, the walkers can help. The default JSON parser is the Jackson which is the most popular one. As it is a key component in our light-4j microservices framework to validate request/response against OpenAPI specification for light-rest-4j and RPC schema for light-hybrid-4j at runtime, performance is the most important aspect in the design. -

Logstash Logback Encoder
Logback JSON encoder and appenders
Provides log back encoders, layouts, and appenders to log in JSON and other formats supported by Jackson. Supports both regular LoggingEvents (logged through a Logger) and AccessEvents (logged via logback-access). Originally written to support output in Logstash's JSON format, but has evolved into a highly configurable, general-purpose, structured logging mechanism for JSON and other Jackson data forms. The structure of the output, and the data it contains, is fully configurable. The general composite JSON encoders/layouts can be used to output any JSON format/data by configuring them with various JSON providers. The Logstash encoders/layouts are really just extensions of the general composite JSON encoders/layouts with a pre-defined set of providers. The logstash encoders/layouts are easier to configure if you want to use the standard logstash version 1 output format. -

EnvFile
EnvFile 3.x is a plugin for JetBrains IDEs
Env File is a plugin for JetBrains IDEs that allows you to set environment variables for your run configurations from one or multiple files. Not all run configurations available in IDEA-based IDEs are implemented similarly. Some of them differ significantly. In certain cases (so far, only Gradle has been confirmed) the implementation exposes interfaces to integrate the EnvFile UI but doesn't provide interfaces for it to actually make its work. Luckily, it was possible to make few assumptions about IDEA's internal implementation and make it work. Such integration is very fragile and it's not immediately clear if it will affect any existing integrations and when it will break. For that reason there is a special option to Enable Experimental Integrations that can be enabled when desired and should prevent other integrations from breaking. -

Ason
This library intends to make JSON very easy to interact with in Java
This library intends to make JSON very easy to interact with in Java; it also makes (de)serialization painless. It wraps around the well-known org.json classes (JSONObject, JSONArray, etc.) which also happen to be included in the Android SDK. As we all know, those stock classes tend to be a pain. They feel bulky, and make you try/catch way too many exceptions. -

OpenEXI
EXI implementations in Java and C#
Open source .Net (C#) / Java implementation of the W3C Efficient XML Interchange (EXI) format specification. As a corollary to XML, EXI is an alternative, very efficient format that has all of the mechanics of XML, but is much more compact and is faster to exchange. - README (about Nagasena EXI implemenation) https://www.dropbox.com/s/adh83u9z1x1czv6/README.txt?dl=0 - Nagasena EXI grammar interchange format (PDF) https://www.dropbox.com/s/etrpuchaddplq2s/EXIGram.pdf?dl=0 - Introduction to OpenEXI (PDF) https://www.dropbox.com/s/n2545xm0jjyui2d/IntroToOpenEXI.pdf?dl=0 -

xsd2pgschema
Relational database replication tool based on XML Schema
xsd2pgschema is a Java application suite, which converts XML Schema 1.1 (hierarchical data model) to PostgreSQL DDL (relational data model) and supports XML data migration into PostgreSQL based on the XML Schema without defects on information content. It also supports full-text indexing via either Apache Lucene or Sphinx Search utilizing the relational data model. File conversion from XML to CSV, TSV, or JSON is possible as well as mapping XML Schema to JSON Schema. Obtained PostgreSQL database can be optimized at user's discretion. Moreover, differential update, and XPath query evaluation over PostgreSQL are possible. PgSchema server, serialized relational data model server, can be used to speed up the analysis of complex XML Schema. Large XML file can be split through xmlsplitter, a flexible XML splitter based on XPath and StAX. -

Artemis
Cassandra "ORM" with hooks for Jersey integration if desired
Using the new CQL3 driver by Datastax Artemis provides extremely easy to use "ORM" like functionality for Cassandra. It also contains hooks for integration into Jersey2 to enable rapid development of RESTful services, or even websites, if you enable JSP functionality for Jersey. If there is a demand, I could add a plugin to render views using things like Velocity, etc. See https://sourceforge.net/p/wicca/wiki/Home/ for more documentation -

Chronicle Wire
Low Garbage Java Serialisation Library that supports multiple formats
Chronicle Wire is a Wire Format abstraction library. Chronicle Wire uses Chronicle Bytes for bytes manipulation, and Chronicle Core for low-level JVM access. Configuration includes aliased type information. This supports easy extension by adding new classes/versions, and cross-platform using type aliasing. By supporting types, a configuration file can bootstrap itself. You control how the configuration file is decoded. See example Queue Enterprise config. To send the configuration of a server to a client, or from a client to a server. Chronicle Wire supports a separation of describing what data you want to store and retrieve, and how it should be rendered/parsed. Chronicle Wire handles a variety of formatting options, for a wide range of formats. -

DSL-JSON library
High performance JVM JSON library
Fastest JVM (Java/Android/Scala/Kotlin) JSON library with advanced compile-time data binding support. Java JSON library designed for performance. Originally built for invasive software composition with DSL Platform compiler. v1 core library was targeting Java6, while v2 targets Java8. So there is no need anymore for dsl-json-java8 project and instead, just dsl-json project should be referenced. From v2 only a single annotation processor is supported, which was previously in the java8 project. Joda and some other specific libraries were removed. If you still need converters for those types, you need to include them in your project. -

Event Ruler
Java library that allows matching many thousands of Events per second
Event Ruler (called Ruler in the rest of the doc for brevity) is a Java library that allows matching Rules to Events. An event is a list of fields, which may be given as name/value pairs or as a JSON object. A rule associates event field names with lists of possible values. Event Ruler is a Java library that allows matching many thousands of Events per second to any number of expressive and sophisticated rules. -

Framework Benchmarks
Source for the TechEmpower Framework Benchmarks project
If you're new to the project, welcome! Please feel free to ask questions here. We encourage new frameworks and contributors to ask questions. We're here to help! This project provides representative performance measures across a wide field of web application frameworks. With much help from the community, coverage is quite broad and we are happy to broaden it further with contributions. The project presently includes frameworks on many languages including Go, Python, Java, Ruby, PHP, C#, F#,Clojure, Groovy, Dart, JavaScript, Erlang, Haskell, Scala, Perl, Lua, C, and others. The current tests exercise plaintext responses, JSON serialization, database reads and writes via the object-relational mapper (ORM), collections, sorting, server-side templates, and XSS counter-measures. Future tests will exercise other components and greater computation.
