Naming Conventions

General Naming Rules

  • Use American English
  • Don't use acronyms
  • Use camelCase unless stated otherwise
  • Reconcile terms with adidas CDM

Every identifier MUST be in American English and written in lowercase. An identifier SHOULD NOT contain acronyms. CamelCase (camelCase) MUST be used to delimit combined words.

URI

Every URI MUST follow the General Rules except for the camelCase rule. Instead, a hyphen (-) SHOULD be used to delimit combined words (kebab-case). Besides, a URI MUST NOT end with a trailing slash (/).

Example

A well-formed URI:

/system-orders/1234/author

Query Parameters and Path Fragments

Every URI query parameter or fragment MUST follow the General Rules. Also, they MUST NOT clash with the reserved query parameter names.

URI Template Variables

In addition to General Naming Rules, URI Template Variable names MUST follow the RFC6570. That is, the variable names can consist only from ALPHA / DIGIT / "_" / pct-encoded.

NOTE: Per RFC6570 Hyphen (-) is NOT legal URI Template variable name character.

Example

A well-formed URI Template Variable:

/system-orders/{orderId}/author

Representation Format Fields

Every representation format field MUST conform to the General Naming Rules.

Example

A well-formed resource representation:

{
  "_links": {
    "self": {
      "href": "/orders/1234"
    },
    "author": {
      "href": "/users/john"
    }
  },
  "orderNumber": 1234,
  "itemCount": 42,
  "status": "pending"
}

Relation Type Identifier

Every custom relation identifier MUST be in lowercase with words separated by the hyphen (-).

Example

A well-formed resource representation with custom relation fulfillment-provider:

{
  "_links": {
    "fulfillment-provider": {
      "href": "/users/natalie"
    }
  }
}

HTTP Headers

Every HTTP Header should use Hyphenated-Pascal-Case. A custom HTTP Header SHOULD NOT start with X- (RFC6648).

Example

Order-Metadata-Header: 42

API Description

Naming conventions within API Description document.

API Name

Every API Description API name MUST start with API domain enclosed in square brackets (e.g. [API Domain] My API). Words MUST be separated by space.

Example

swagger: '2.0'
info:
  version: '1.0.0'
  title: '[Demo] Orders API'

Resource Name

Every resource MUST have a name (defined by x-summary field). Resource name MUST be in Title Case. Words MUST be separated by a space.

Example

/orders:
  x-summary: List of Orders

Action Name

Every action (operation) MUST have a name (defined by summary field). Action name MUST be in Title Case. Words MUST be separated by a space.

Example

get:
  summary: Retrieve List of Orders
