spatie/schema-org provides a fluent builder for all Schema.org types and their properties. The code in src is generated from Schema.org's RDFa standards file, so it provides objects and methods for the entire core vocabulary. The classes and methods are also fully documented as a quick reference.

use Spatie\SchemaOrg\Schema;

$localBusiness = Schema::localBusiness()
    ->name('Spatie')
    ->email('info@spatie.be')
    ->contactPoint(Schema::contactPoint()->areaServed('Worldwide'));

echo $localBusiness->toScript();
<script type="application/ld+json">
{
    "@context": "http:\/\/schema.org",
    "@type": "LocalBusiness",
    "name": "Spatie",
    "email": "info@spatie.be",
    "contactPoint": {
        "@type": "ContactPoint",
        "areaServed": "Worldwide"
    }
}
</script>

Installation

You can install the package via composer:

composer require spatie/schema-org

Usage

All types can be instantiated through the Spatie\SchemaOrg\Schema factory class, or with the new keyword.

$localBusiness = Schema::localBusiness()->name('Spatie');

// Is equivalent to:

$localBusiness = new LocalBusiness();
$localBusiness->name('Spatie');

All types also accept arrays of the expected data type, for example sameAs accepts a string or an array of strings.

All types also implement the SPL's ArrayAccess for accessing the properties via array notation:

$anotherLocalBusiness = new LocalBusiness();
var_dump(isset($anotherLocalBusiness['name'])); // => false
$anotherLocalBusiness['name'] = 'Spatie';
var_dump(isset($anotherLocalBusiness['name'])); // => true
var_dump($anotherLocalBusiness['name']); // => 'Spatie'
unset($anotherLocalBusiness['name']);
var_dump(isset($anotherLocalBusiness['name'])); // => false

Types can be converted to an array or rendered to a script.

$localBusiness->toArray();

echo $localBusiness->toScript();

echo $localBusiness; // Same output as `toScript()`

Additionally, all types can be converted to a plain JSON string by just calling json_encode() with your object:

echo json_encode($localBusiness);

I recommend double checking your structured data with Google's structured data testing tool.

Enumerations

As of v1.6.0, all Enumeration child types are available as classes with constants.

Schema::book()->bookFormat(Spatie\SchemaOrg\BookFormatType::Hardcover);

There's no full API documentation for types and properties. You can refer to the source or to the schema.org website.

If you don't want to break the chain of a large schema object, you can use the if method to conditionally modify the schema.

use Spatie\SchemaOrg\LocalBusiness;
use Spatie\SchemaOrg\Schema;

$business = ['name' => 'Spatie'];

$localBusiness = Schema::localBusiness()
    ->name($business['name'])
    ->if(isset($business['email']), function (LocalBusiness $schema) {
        $schema->email($business['email']);
    });

Identifier

As of v2.6.0 the identifier key is replaced by @id. This is due to the definition for the ld+json syntax.

All schema.org syntaxes already have built-in representation for URIs and URLs, e.g. in Microdata 'itemid', in RDFa 1.1, 'resource', in JSON-LD, '@id'.

Advanced Usage

If you'd need to set a custom property, you can use the setProperty method.

$localBusiness->setProperty('foo', 'bar');

If you'd need to retrieve a property, you can use the getProperty method. You can optionally pass in a second parameter to provide a default value.

$localBusiness->getProperty('name'); // 'Spatie'
$localBusiness->getProperty('bar'); // null
$localBusiness->getProperty('bar', 'baz'); // 'baz'

All properties can be retrieved as an array with the getProperties method.

$localBusiness->getProperties(); // ['name' => 'Spatie', ...]

Multiple properties can be set at once using the addProperties method.

$localBusiness->addProperties(['name' => 'value', 'foo' => 'bar']);

Context and type can be retrieved with the getContext and getType methods.

$localBusiness->getContext(); // 'http://schema.org'
$localBusiness->getType(); // 'LocalBusiness'

Graph - multiple items

The Graph has a lot of methods and utilities - the type-safe and simplest way is to use the overloaded methods of the Spatie\SchemaOrg\Schema class itself. These methods will get an already created or new instance of the requested schema.

$graph = new Graph();

// Create a product and prelink organization
$graph
    ->product()
    ->name('My cool Product')
    ->brand($graph->organization());

// Hide the organization from the created script tag
$graph->hide(\Spatie\SchemaOrg\Organization::class);

// Somewhere else fill out the organization
$graph
    ->organization()
    ->name('My awesome Company');

// Render graph to script tag
echo $graph;

With these tools the graph is a collection of all available schemas, can link these schemas with each other and prevent helper schemas from being rendered in the script-tag.

Known Issues

  • The Float type isn't available since it's a reserved keyword in PHP
  • The Physician type isn't available since it extends a type from the health extension spec
