Domain

A .play file can declare the domain it belongs to. The domain is a qualified name that groups related files — typically the name of the business domain a bounded context sits in.

Syntax

domain <Qualified.Name>

Rules

• Optional — a file without a domain line belongs to no domain.
• At most one per file — a second domain line is a compile error.
• First in the file — the declaration must appear before everything else, including imports.

Example

domain Sales

import Customers.CustomerRegistered

module Invoicing
  ...
