The following options can be used in the configuration file.

Customizing PHP Namespaces

Namespaces of generated PHP classes can be set globally, respectively for entities, enumerations and interfaces (if used with Doctrine Resolve Target Entity Listener option).


    entity: "App\ECommerce\Entity"
    enum: "App\ECommerce\Enum"
    interface: "App\ECommerce\Model"

Namespaces can also be specified for a specific type. It will take precedence over any globally configured namespace.


            class: "App\Common\Entity" # Namespace for the Thing entity (works for enumerations too)
            interface: "App\Schema\Model" # Namespace of the related interface

Forcing a Field Type (Range)

RDF allows a property to have several types (ranges). However, the generator allows only one type by property. If not configured, it will use the first defined type. The range option is useful to set the type of a given property. It can also be used to force a type (even if not in the RDF vocabulary definition).


            logo: { range: "ImageObject" } # Force the range of the logo property to ImageObject (can also be a URL according to Schema.org)

            addressCountry: { range: "Text" } # Force the type to Text instead of Country. It will be converted to the PHP string type.

Forcing a Field Cardinality

The cardinality of a property is automatically guessed. The cardinality option allows to override the guessed value. Supported cardinalities are:

  • (0..1): scalar, not required
  • (0..*): array, not required
  • (1..1): scalar, required
  • (1..*): array, required
  • (*..0)
  • (*..1)
  • (*..*)

Cardinalities are enforced by the class generator, the Doctrine ORM generator and the Symfony validation generator.


                cardinality: "(0..1)"

Changing the Default Cardinality

When a cardinality has not been guessed, a default cardinality will be used instead.

By default, the cardinality (1..1) is used, but you can change it like this:

    defaultCardinality: "(1..*)"

Adding a Custom Attribute or Modifying a Generated Attribute

You can add any custom attribute you want, or you can modify the arguments of any generated attribute, for a property, a class or even a whole vocabulary!

For instance, if you want to change the join table name and add security for a specific relation:

                    ORM\JoinTable: { name: organization_contactPoint } # Instead of organization_contact_point by default
                    ApiProperty: { security: "is_granted('ROLE_ADMIN')" }

To add a custom attribute, you also need to add it in the uses option:

    App\Attributes\MyAttribute: ~

            - ApiResource: { routePrefix: '/library' } # Add a route prefix for this resource
            - MyAttribute: ~
            # Note the optional usage of a hyphen list: it allows to preserve the order of attributes

Forcing (or Enabling) a Class Parent

Override the guessed class hierarchy of a given type with this option.


        parent: Thing # Force the parent to be Thing instead of CreativeWork > MediaObject
        properties: ~
        parent: ~ # Enable the class hierarchy for this type

Forcing a Class to be Abstract

Force a class to be (or to not be) abstract. By default, it will be guessed, depending on the class hierarchy and if the class is used in a relation.


        abstract: true

Define API Platform Operations

API Platform operations can be added this way:

            Get: ~
                routeName: get_person_collection

Forcing a Nullable Property

Force a property to be (or to not be) nullable.

By default, this option is null: the cardinality will be used to determine the nullability. If no cardinality is found, it will be true.


            name: { nullable: false }

The #[Assert\NotNull] constraint is automatically added.


 * The name of the item.
private string $name;

Forcing a Unique Property

Force a property to be (or to not be) unique.

By default, this option is false.


            email: { unique: true }


// api/src/Entity/Person.php
namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Doctrine\ORM\Mapping as ORM;

 * A person (alive, dead, undead, or fictional).
 * @see https://schema.org/Person
#[ApiResource(types: ['https://schema.org/Person'])]
class Person
     * Email address.
     * @see https://schema.org/email
    private string $email;

    // ...

Making a Property Read-Only

A property can be marked read-only with the following configuration:

            email: { writable: false }

In such case, no mutator method will be generated.

Making a Property Write-Only

A property can be marked write-only with the following configuration:

            email: { readable: false }

In this case, no getter method will be generated.

Forcing an Embeddable Class to be Embedded

Force an embeddable class to be embedded.


        embeddable: true
            weight: { range: "QuantitativeValue", embedded: true }


// api/src/Entity/Product.php
namespace App\Entity;

use ApiPlatform\Metadata\ApiProperty;
use ApiPlatform\Metadata\ApiResource;
use Doctrine\ORM\Mapping as ORM;

 * Any offered product or service.
 * @see https://schema.org/Product Documentation on Schema.org
#[ApiResource(types: ['https://schema.org/Product'])]
class Product
     * The weight of the product or person.
     * @see https://schema.org/weight
    #[ORM\Embedded(class: QuantitativeValue::class)]
    #[ApiProperty(iri: 'https://schema.org/weight')]
    private ?QuantitativeValue $weight = null;

    // ...

Skipping Accessor Method Generation

It's possible to skip the generation of accessor methods. This is particularly useful combined with the visibility: public option.

To skip the generation of accessor methods, use the following config:

accessorMethods: false

Using Fluent Mutator Methods

If you want to generate fluent mutator methods, like this:

public function setName(?string $name): self
    $this->name = $name;

    return $this;

Use the following config:

fluentMutatorMethods: true

Disabling the id Generator

By default, the generator adds a property called id not provided by Schema.org. This is useful when generating an entity for use with an ORM or an ODM but not when generating DTOs. This behavior can be disabled with the following setting:

    generate: false

Generating UUIDs

It's also possible to let the DBMS generate UUIDs instead of auto-incremented integers:

    generationStrategy: uuid

User-submitted UUIDs

To manually set a UUID instead of letting the DBMS generate it, use the following config:

    generationStrategy: uuid
    writable: true

Generating Custom IDs

With this configuration option, an $id property of type string and the corresponding getters and setters will be generated, but the DBMS will not generate anything. The ID must be set manually.

    generationStrategy: none

Disabling Usage of Doctrine Collections

By default, the generator uses classes provided by the Doctrine Collections library to store collections of entities. This is useful (and required) when using Doctrine ORM or Doctrine MongoDB ODM. This behavior can be disabled (to fall back to standard arrays) with the following setting:

    useCollection: false

Changing the Field Visibility

Generated fields have a private visibility and are exposed through getters and setters. The default visibility can be changed with the fieldVisibility option.


fieldVisibility: "protected"

Generating Assert\Type Attributes

It's possible to automatically generate Symfony validator's #[Assert\Type] attributes using the following config:

    assertType: true

Forcing Doctrine Inheritance Mapping Attribute

The generator is able to handle inheritance in a smart way:

  • If a class has children and is referenced by a relation, it will generate an inheritance mapping strategy with #[InheritanceType] (configurable, see below), #[DiscriminatorColumn] (#[DiscriminatorField] for ODM) and #[DiscriminatorMap]. The discriminator map will be filled with all possible values.
  • If a class has children but is not referenced by a relation, it will generate a mapped superclass (#[MappedSuperclass]). If this mapped superclass defines relations and is used by multiple children, the generator will add #[AssociationOverride] attributes to them (see the related Doctrine documentation), thanks to the special DoctrineOrmAssociationOverrideAttributeGenerator.
  • If a class has no child, an #[Entity] (or #[Document] for ODM) attribute is used.

If this behaviour does not suit you, the inheritance attribute can be forced in the following way:

    inheritanceType: SINGLE_TABLE # Default: JOINED
        CustomInheritanceAttribute: []

Interfaces and Doctrine Resolve Target Entity Listener

ResolveTargetEntityListener is a feature of Doctrine to keep modules independent. It allows to specify interfaces and abstract classes in relation mappings.

If you set the option useInterface to true, the generator will generate an interface corresponding to each generated entity and will use them in relation mappings.

To let the schema generator generate the mapping file usable with Symfony, add the following to your config file:

    resolveTargetEntityConfigPath: path/to/doctrine.xml

The default mapping file format is XML, but you can change it to YAML with the following option:

    resolveTargetEntityConfigPath: path/to/doctrine.yaml
    resolveTargetEntityConfigType: YAML # Supports XML & YAML

Doctrine Resolve Target Entity Config Type

By default, the mapping file is in XML. If you want to have a YAML file, add the following:

    resolveTargetEntityConfigPath: path/to/doctrine.yaml
    resolveTargetEntityConfigType: yaml

Custom Schemas

The generator can use your own schema definitions. They must be written in RDF/XML and follow the format of the Schema.org's definition. This is useful to document your Schema.org extensions and use them to generate the PHP data model of your application.


    - https://github.com/schemaorg/schemaorg/raw/main/data/releases/13.0/schemaorg-current-https.rdf
    - http://example.com/data/myschema.rdf # Additional types

You can also use any other vocabulary. Check the Linked Open Vocabularies to find one fitting your needs.

For instance, to generate a data model from the Video Game Ontology, use the following config file:

    - http://vocab.linkeddata.es/vgo/GameOntologyv3.owl # The URL of the vocabulary definition

        vocabularyNamespace: http://purl.org/net/VideoGameOntology#

  # ...

All Types, Resolve Types and Exclude

If you use multiple vocabularies, and you need to generate all types for some ones, only generate types when they are used for some others and exclude some types, you can do so with this kind of configuration:

    # Schema.org classes will only be generated when one of its type is used in the other vocabularies.
    - { uri: 'https://schema.org/version/latest/schemaorg-current-https.rdf', format: null, allTypes: false }
    - http://vocab.linkeddata.es/vgo/GameOntologyv3.owl

allTypes: true # Generate all types by default for vocabularies
resolveTypes: true # Resolve types in other vocabularies

        exclude: true # Exclude the GameEvent type

Checking GoodRelation Compatibility

If the checkIsGoodRelations option is set to true, the generator will emit a warning if an encountered property is not par of the GoodRelations schema.

This is useful when generating e-commerce data models.

Author PHPDoc

Add a @author PHPDoc annotation to class DocBlock.

Disabling Generators and Creating Custom Ones

By default, all generators except DoctrineMongoDBAttributeGenerator are enabled. You can specify the list of generators to use with the annotationGenerators and attributeGenerators option.

Example (enabling only the PHPDoc generator):

    - ApiPlatform\SchemaGenerator\AnnotationGenerator\PhpDocAnnotationGenerator
attributeGenerators: []

You can write your own generators by implementing the AnnotationGeneratorInterface or AttributeGeneratorInterface. The AbstractAnnotationGenerator or AbstractAttributeGenerator provides helper methods useful when creating your own generators.

Enabling a custom attribute generator and the PHPDoc generator:

    - ApiPlatform\SchemaGenerator\AnnotationGenerator\PhpDocAnnotationGenerator
    - Acme\Generators\MyGenerator
