Spike goals:

check if it is possible to define a RAML file without any endpoints just to declare traits and imports, the goal is to generate DTOs and reusable traits.
check if it is possible to extend or inherit JSON schemas. if not demonstrate how to include or wrap JSON schemas.

check if it is possible to define a RAML file without any endpoints just to declare traits and imports, the goal is to generate DTOs and reusable traits

Unfortunately, it is not possible to declare RAML file without any endpoint, one endpoint with at least one method should exist.

check if it is possible to extend or inherit JSON schemas. if not demonstrate how to include or wrap JSON schemas.

It is possible to extend JSON schemas. The detailed information on how to do it described below.

Let's assume we have following raml file

Code Block

theme	Confluence
title	library.raml

#%RAML 1.0

title: Book Library API
version: v0.1

documentation:
  - title: Introduction
    content: Automated access to books
  - title: Licensing
    content: Please respect copyrights on our books.

types:
  book: !include bookParent.json
  bookCollection: !include bookCollection.json
  errors: !include raml-util/schemas/errors.schema

traits:
  language: !include raml-util/traits/language.raml

resourceTypes:
  collection: !include raml-util/rtypes/collection.raml
  collection-item: !include raml-util/rtypes/item-collection.raml

/books:
  description: The collection of library books
  type:
    collection:
      schemaCollection: bookCollection
      schemaItem: book
      exampleCollection: !include examples/bookCollection.sample
      exampleItem: !include examples/book.sample

The definition of the book collection looks similar to other collections used in project

Code Block

theme	Confluence
title	bookCollection.json

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "description": "Collection of books",
  "properties": {
    "books": {
      "type": "array",
      "items": {
        "type": "object",
        "$ref": "bookChild.json"
      }
    },
    "totalRecords": {
      "type": "integer"
    }
  },
  "required": [
    "books",
    "totalRecords"
  ]
}

Here, for the reference field I have used "bookChild.json" file, which is a child of other json file

Code Block

theme	Confluence
title	bookParent.json

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "description": "A book parent",
  "additionalProperties": false,
  "properties": {
    "id": {
      "type": "string"
    },
    "name": {
      "description": "The name of the book",
      "type": "string"
    },
    "author": {
      "description": "The author of the book",
      "type": "string"
    },
    "metadata": {
      "description": "Metadata about creation and changes, provided by the server (client should not provide)",
      "type": "object",
      "$ref": "raml-util/schemas/metadata.schema",
      "readonly": true
    }
  },
  "required": [
    "name",
    "author"
  ]
}

Code Block

theme	Confluence
title	bookChild.json

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "description": "A book child",
  "additionalProperties": false,
  "extends" : {
    "$ref" : "bookParent.json"
  },
  "properties": {
    "publisher": {
      "description": "The publisher of the book",
      "type": "string"
    }
  }
}

The main point is to use

Code Block
"extends" : { "$ref" : "<json_file>" }

After project build we will have following models:
