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.


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 (/).

Plural nouns SHOULD be used in the URI where appropriate to identify collections of data resources (e.g. /orders, /products).

An individual resource in a collection of resources MAY exist directly beneath the collection URI. (e.g. /orders/{order_id}).


A well-formed URI:


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.


A well-formed URI Template Variable:


Representation Format Fields

A well-formed resource representation:

      "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 (-).

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