## What it is
JSON-java (org.) is a reference implementation of a JSON package in Java, providing parsers, encoders, and decoders for JSON documents. It also converts between JSON and XML, HTTP headers, Cookies, and CDL, with no external dependencies.

## Use cases
- parse  in java
- serialize java objects to
- convert  to xml
- read  from http responses
- generate  documents in java
- handle cookies and http headers as

## When to choose
- you need a lightweight, zero-dependency JSON library for Java
- you want a stable, spec-compliant reference implementation
- you need JSON-to-XML or JSON-to-CDL conversion
- you need a public-domain library usable in commercial projects without attribution

## When to avoid
- you need high-performance streaming JSON parsing for very large documents
- you want data-binding to POJOs like Jackson provides
- you need a library with active feature development, since the project is in maintenance mode

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser
- domain: developer-tools, apis, files
- platform: jvm, cross-platform
- tags: -parser, -serializer, public-domain, zero-dependencies, xml-conversion
