Api-blueprint: Estendendo Estruturas de Dados

Olá, tenho uma pergunta / proposta sobre estruturas de dados. Talvez seja mais relacionado ao MSON, mas vou começar aqui. Para manter as estruturas de dados organizadas e organizadas, gostaria de ter o mínimo possível de dados duplicados, portanto, seria bom se as estruturas de dados pudessem se estender.

Suponha a seguinte estrutura de dados:

# Data Structures

## Project_Link (object) 
+ self: `https://test.api.com/projects/5` (string, required)

## Project1_Get (object)
+ type: `projects` (string, required)
+ id: `5` (string, required)
+ attributes (object, required)
    + number: `PRO-5` (string) - A readable identifier for employees to refer to projects.
+ links (Project_Link, required)

No atributo links de Project1_Get eu reutilizo o objeto Project_Link que funciona muito bem. Mas suponha que eu precise da seguinte DataStructure também:

## Project1_Identifier (object)
+ type: `projects` (string, required)
+ id: `5` (string, required)

Agora há dados duplicados em minhas estruturas de dados porque Project1_Identifier contém o atributo type e id , mas também Project1_Get contém. Seria ótimo se eu pudesse fazer o seguinte:

# Data Structures

## Project1_Link (object) 
+ self: `https://test.api.com/projects/5` (string, required)

## Project1_Identifier (object)
+ type: `projects` (string, required)
+ id: `5` (string, required)

## Project1_Get (Project_Identifier) <--- Extend!
+ attributes (object, required)
    + number: `PRO-5` (string) - A readable identifier for employees to refer to projects.
+ links (Project1_Link, required)

No exemplo a seguir, o redator retorna erros:

FORMAT: 1A
HOST: https://test.api.com/

# Test API
Hi, welcome to the API!

# Group Projects
Wow, we are using projects!

### Retrieve single project [GET /projects/{id}]
+ Parameters
    + id: `5` (string, required)

+ Response 200 (application/json)
    + Attributes (object)
        + data (Project1_Get, required)

# Data Structures

## Project_Link (object) 
+ self: `https://test.api.com/projects/5` (string, required)

## Project_Identifier (object)
+ type: `projects` (string, required)
+ id: `5` (string, required)

## Project1_Get (Project_Identifier)
+ type: `projects` (string, required)
+ id: `5` (string, required)
+ attributes (object, required)
    + number: `PRO-5` (string) - A readable identifier for employees to refer to projects.
+ links (Project_Link, required)
