Resources Components for Laravel

Search for entities in authority databases and link them with your local data using Livewire components. This package provides a seamless integration with various data providers to enhance your Laravel application with external resources.

Supported Providers

• GND (Gemeinsame Normdatei)
• Geonames (Geographical database)
• Wikipedia (Multiple languages: DE, EN, FR, IT)
• Wikidata (Structured data)
• Idiotikon (Swiss German dictionary)
• Ortsnamen.ch (Swiss place names)
• Metagrid (Swiss humanities database network)
• Anton API (Archives and collections)
  • Archiv der Georg Fischer AG
  • Gosteli Archiv
  • Karl Barth-Archiv
• Manual Input (Custom links)

Requirements

• PHP 8.1 or higher
• Laravel 10.x or 11.x
• Livewire 3.4+
• kraenzle-ritter/resources package

Installation

Via Composer:

composer require kraenzle-ritter/resources-components

After installation, you can publish various assets:

Configuration

Publish the configuration file to customize provider settings:

php artisan vendor:publish --tag=resources-components.config

This will create config/resources-components.php where you can:

• Configure API endpoints and credentials
• Add custom providers
• Modify provider labels and URLs
• Set environment-specific settings (API tokens, etc.)

Language Files

Publish translation files for customization:

php artisan vendor:publish --tag=resources-components.lang

All Assets

Publish everything at once:

php artisan vendor:publish --provider="KraenzleRitter\ResourcesComponents\ResourcesComponentsServiceProvider"

Testing

This package includes comprehensive tests to ensure proper functionality of all providers. Run the tests with:

vendor/bin/phpunit

Basic Usage

In your views, use the components like this:

@livewire('resources-list', [$model, 'deleteButton' => true])
@livewire('provider-select', [$model, $providers, 'actors'])

Where:

• $model is the model that should become resourceable (must use the HasResources trait)
• $providers is an array of provider keys to enable (e.g., ['gnd', 'geonames', 'wikipedia-de', 'manual-input'])
• The third parameter ('actors') is the endpoint entity type (only required for Anton API providers)

Configuration

The package comes with a pre-configured setup for various providers. After publishing the configuration file (see Installation), you can customize provider settings in config/resources-components.php:

// config/resources-components.php
return [
    'limit' => 5, // Default search results limit
    'providers' => [
        'gnd' => [
            'label' => 'GND',
            'api-type' => 'Gnd',
            'base_url' => 'https://lobid.org/gnd/',
            'target_url' => 'https://d-nb.info/gnd/{provider_id}',
            'test_search' => 'Hannah Arendt', // Test query for provider check page
        ],
        'wikipedia-de' => [
            'label' => 'Wikipedia (DE)',
            'api-type' => 'Wikipedia',
            'base_url' => 'https://de.wikipedia.org/w/api.php',
            'target_url' => 'https://de.wikipedia.org/wiki/{underscored_name}',
            'test_search' => 'Bertha von Suttner',
        ],
        // Add more providers here
    ],
];

Provider Configuration Options

Each provider supports the following configuration options:

• label (string): Display name for the provider
• api-type (string): Provider class name (e.g., 'Gnd', 'Wikipedia', 'Wikidata')
• base_url (string): Base URL for API requests
• target_url (string): URL template for saved resources (supports placeholders like {provider_id})
• test_search (string): Test query used by the provider check page to verify functionality
• limit (integer, optional): Provider-specific result limit (overrides global limit)

Additional provider-specific options may apply (e.g., user_name for Geonames, api_token for Anton providers).

Creating Custom Providers

You can create your own provider by implementing the ProviderInterface or extending the AbstractProvider class:

1. Create a provider class:

namespace App\Providers;

use KraenzleRitter\ResourcesComponents\Providers\AbstractProvider;

class MyCustomProvider extends AbstractProvider
{
    public function search(string $search, array $params = [])
    {
        // Implement search logic
    }
    
    public function processResult($results): array
    {
        // Process results into standard format
        return [
            [
                'title' => 'Result title',
                'description' => 'Result description',
                'url' => 'https://example.com/resource',
                'raw_data' => json_encode($data)
            ],
            // More results...
        ];
    }
}

1. Register your provider in the configuration:

'my-provider' => [
    'label' => 'My Provider',
    'api-type' => 'MyCustom',
    'base_url' => 'https://api.example.com/',
    'provider_class' => App\Providers\MyCustomProvider::class,
],

Customizing Views

You can publish and customize the views:

php artisan vendor:publish --provider="KraenzleRitter\ResourcesComponents\ResourcesComponentsServiceProvider" --tag=resources-components.views

Handling Resource Events

The components fire an event (ResourceSaved) when saving a resource. You can define and register a listener in your app:

<?php

namespace App\Listeners;

use KraenzleRitter\ResourcesComponents\Events\ResourceSaved;

class UpdateLocationWithGeonamesCoordinates
{
    public function handle(ResourceSaved $event)
    {
        if ($event->resource->provider == 'geonames') {
            // Access resource data
            \Log::debug($event->resource);
            
            // Access the model that the resource is attached to
            \Log::debug($event->model);
            
            // Example: Update location coordinates from Geonames data
            if (isset($event->resource->data['lat']) && isset($event->resource->data['lng'])) {
                $event->model->update([
                    'latitude' => $event->resource->data['lat'],
                    'longitude' => $event->resource->data['lng']
                ]);
            }
        }
    }
}

Register your listener in EventServiceProvider.php:

<?php
namespace App\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
use KraenzleRitter\ResourcesComponents\Events\ResourceSaved;
use App\Listeners\UpdateLocationWithGeonamesCoordinates;

class EventServiceProvider extends ServiceProvider
{
    protected $listen = [
        ResourceSaved::class => [
            UpdateLocationWithGeonamesCoordinates::class
        ]
    ];
}

Configuration

Environment Variables

Some providers require additional configuration in your .env file:

# For Geonames
GEONAMES_USERNAME=your_username

# Anton API Providers (georgfischer, kba, gosteli)
# No API tokens required for these providers

Model Requirements

Your models must:

1. Use the HasResources trait from the kraenzle-ritter/resources package
2. Have either a resource_search attribute or a name attribute (used as default search term)

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use KraenzleRitter\Resources\HasResources;

class Person extends Model
{
    use HasResources;
    
    // The rest of your model...
}

Creating Custom Providers

To create a new provider, you need:

1. A provider class that implements the search functionality
2. A Livewire component class for the UI interaction
3. Configuration in the resources-components.php file

See the documentation or existing providers for implementation details.
