$edges

The list of all edges definitions to generates the complex edge attributes or resolve and create the Edges dependencies in the DI Container.

1 - Use an associative array to manage the attributes with an Edges relation.

$documents = new Documents
([
    AQL::COLLECTION => Collections::PLACES ,
    AQL::DATABASE   => Databases::ARANGO ,
    AQL::SCHEMA     => Place::class ,
    AQL::EDGES      =>
    [
        Schema::ADDITIONAL_TYPE =>
        [
             AQL::MODEL => EdgesDefinition::PLACE_HAS_TYPE ,
        ]
        Schema::CONTAINED_IN_PLACE => // $to -> $from
        [
            AQL::MODEL     => EdgesDefinition::PLACE_CONTAINS_PLACE ,
            AQL::DIRECTION => Traversal::INBOUND ,
            AQL::SORT      => Prop::NAME ,
            AQL::ORDER     => Order::ASC ,
            AQL::SKIN      => Skin::DEFAULT
        ],
        Schema::CONTAINS_PLACE => // $from -> $to
        [
             AQL::MODEL  => EdgesDefinition::PLACE_CONTAINS_PLACE ,
             AQL::SORT  => Prop::NAME ,
             AQL::SKIN  => Skin::DEFAULT ,
             AQL::FIELDS => // custom fields
             [
                   Prop::_KEY     => Filter::DEFAULT  ,
                   Prop::NAME     => Filter::DEFAULT  ,
                   Prop::CREATED  => Filter::DATETIME ,
                   Prop::MODIFIED => Filter::DATETIME ,
             ]
        ]
        // Reference an other edges definition
        Schema::NUM_CONTAINS_PLACE => Schema::CONTAINS_PLACE
    ],
    AQL::FIELDS =>
    [
        Schema::_KEY               => Filter::DEFAULT ,
        Schema::NAME               => Filter::DEFAULT ,
        Schema::CREATED            => Filter::DATETIME ,
        Schema::MODIFIED           => Filter::DATETIME ,
        Schema::ADDITIONAL_TYPE    => Filter::EDGE ,
        Schema::CONTAINED_IN_PLACE => Filter::EDGES ,
        Schema::CONTAINS_PLACE     => Filter::EDGES ,
        Schema::NUM_CONTAINS_PLACE => Filter::EDGES_COUNT ,
    ]
]) ;

$places = $documents->list([ AQL::LIMIT => 0 ]) ;

echo( json_encode( $places , JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT ) ) ;

2 - Use an indexed array to resolves the Edges definition in the DI Container.

$documents = new Documents
([
    AQL::COLLECTION => Collections::PLACE_TYPES ,
    AQL::DATABASE   => Databases::ARANGO ,
    AQL::SCHEMA     => DefinedTerm::class ,
    AQL::EDGES      =>
    [
        EdgesDefinition::PLACE_HAS_TYPE ,
        // ... others Edges definitions
    ],
])

3 - Mix the Edges configurations and the Edges only resolving in the DI Container.

$documents = new Documents
([
    AQL::COLLECTION => Collections::PLACE_TYPES ,
    AQL::DATABASE   => Databases::ARANGO ,
    AQL::SCHEMA     => DefinedTerm::class ,
    AQL::EDGES      =>
    [
         AQL::RESOLVE =>
         [
              EdgesDefinition::PLACE_HAS_TYPE ,
              // ... others Edges definitions
         ] ,

    ],
    Schema::CONTAINS_PLACE =>
    [
        AQL::MODEL => EdgesDefinition::PLACE_CONTAINS_PLACE ,
    ]
])
