We provide documentation for both [JSON Schema](http://json-schema.org/ "JSON Schema") standard itself as well as for the library's own API. ### License [](#license) **Opis JSON Schema** is licensed under the [Apache License, Version 2.0](https://www.apache.org/licenses/LICENSE-2.0 "Apache License"). ### Requirements [](#requirements) - PHP ^7.4 || ^8.0 || ^8.1 Installation ------------ [](#installation) **Opis JSON Schema** is available on [Packagist](https://packagist.org/packages/opis/json-schema "Packagist") and it can be installed from a command line interface by using [Composer](https://getcomposer.org "Composer"). ``` composer require opis/json-schema ``` Or you could directly reference it into your `composer.json` file as a dependency ``` { "require": { "opis/json-schema": "^2.2" } } ``` ### Health Score 28 — LowBetter than 54% of packages Maintenance31 Infrequent updates — may be unmaintained Popularity8 Limited adoption so far Community16 Small or concentrated contributor base Maturity50 Maturing project, gaining track record Bus Factor1 Top contributor holds 75.4% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
