This bundle provides a thin integration for rendering JSON-LD meta data tags.

Creating a schema

Before you can render the meta data inside your templates, you need to implement a SchemaBuilderInterface for each entity type, that you want to generate a JSON-LD schema for.

An example SchemaBuilderInterface implementation would look like this, which would convert an MyNewsArticle into a Article.

use App\Entity\MyNewsArticle;
use Becklyn\SchemaOrg\Data\Article;
use Becklyn\SchemaOrg\Data\Organization;
use Becklyn\SchemaOrg\Data\SchemaOrgDataInterface;
use Becklyn\SchemaOrg\SchemaBuilder\SchemaBuilderInterface;

class MyNewsSchemaBuilder implements SchemaBuilderInterface
     * @inheritDoc
    public function supports ($entity, ?string $usage = null, array $context = []) : bool
        return $entity instanceof MyNewsArticle;

     * @inheritDoc
    public function buildSchema ($entity, ?string $usage = null, array $context = []) : ?SchemaOrgDataInterface
        \assert($entity instanceof MyNewsArticle);

        // Don't generate metadata for unpublished news
        if (!$entity->isPublished())
            return null;

        return (new Article())
                (new Organization())
                    ->withName("Awesome Publisher")
            ->withLicense("Creative Commons Attribution-ShareAlike 3.0")

Render meta data tag

To render the JSON-LD meta data tag, call the Twig function {{ schema_org_meta_data(myAppEntity) }} and pass in an optional usage and context parameter, if you need to tweak the output based on the current render context.
