**jskos** is a PHP library for easy processing of knowledge organization systems (KOS) as classifications, thesauri, and authority files given in [JSKOS data format](http://gbv.github.io/jskos/). JSKOS is a JSON format based on [Simple Knowledge Organisation System (SKOS)](http://www.w3.org/TR/skos-reference).

Requirements
============

[](#requirements)

JSKOS-PHP requires PHP 7.2. No additional libraries are required.

Installation
============

[](#installation)

With composer
-------------

[](#with-composer)

Install the latest version with

```
composer require gbv/jskos
```

This will automatically create `composer.json` for your project (unless it already exists) and add jskos as dependency. Composer also generates `vendor/autoload.php` to get autoloading of all dependencies:

```
require_once __DIR__ . '/vendor/autoload.php';

$concept = new JSKOS\Concept( [ "uri" => "http://example.org" ] );
echo $concept->json();
```

Usage and examples
==================

[](#usage-and-examples)

The [jskos-php-examples repository](https://github.com/gbv/jskos-php-examples)contains several examples, including wrappers of existing terminology services (Wikidata, GND...) to JSKOS-API.

The examples can be tried online at .
