This repository contains a wrapper to access the [Virtual International Authority File (VIAF)](http://viaf.org) in [JSKOS format](https://gbv.github.io/jskos/) via [Entity Lookup Microservice API (ELMA)](http://gbv.github.io/elma/).

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

[](#requirements)

Requires PHP 7, [jskos-rdf](https://packagist.org/packages/gbv/jskos-rdf) package and a [HTTP client-implementation](https://packagist.org/packages/php-http/client-implementation) package.

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

[](#installation)

Install a HTTP client implementation package, e.g. [curl-client](https://packagist.org/packages/php-http/curl-client) and this package:

```
composer require php-http/curl-client gbv/viaf-jskos
```

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

Usage
=====

[](#usage)

The wrapper can be used as instance of class `\JSKOS\Service\VIAF`, a subclass of `\JSKOS\Service`:

```
require 'vendor/autoload.php';

$service = new \JSKOS\Service\VIAF();

$jskos = $service->queryURI("http://viaf.org/viaf/102333412");
$jskos = $service->query(["uri" => "http://viaf.org/viaf/102333412"]);
$jskos = $service->query(["notation" => "102333412"]);
```

This repository contains a command line script to query VIAF in JSKOS format:

```
php examples/viaf2jskos.php http://viaf.org/viaf/102333412
php examples/viaf2jskos.php 102333412
php examples/viaf2jskos.php Jane Austen

```
