jskos - JSKOS data model in PHP

jskos is a PHP library for easy processing of knowledge organization systems (KOS) as classifications, thesauri, and authority files given in JSKOS data format. JSKOS is a JSON format based on Simple Knowledge Organisation System (SKOS).

Requirements

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

Installation

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

The jskos-php-examples repository contains several examples, including wrappers of existing terminology services (Wikidata, GND...) to JSKOS-API.

The examples can be tried online at https://jskos-php-examples.herokuapp.com.
