Knowledge Level

The Knowledge Level pattern can be used on bounded contexts and aggregates to specify their knowledge level, which can be one of the following values:

  • CONCRETE
  • META

Syntax

The following examples show how you can specify the knowledge level on a bounded context and on an aggregate:

BoundedContext CustomerManagementContext implements CustomerManagementDomain {
  type = FEATURE
  domainVisionStatement = "The customer management context is responsible for ..."
  implementationTechnology = "Java, JEE Application"
  knowledgeLevel = CONCRETE
}

Aggregate Customers {
  responsibilities = Customers, Addresses { "Address description ..." }
  knowledgeLevel = CONCRETE
    
  Entity Customer { 
    aggregateRoot
    
    - SocialInsuranceNumber sin
    String firstname
    String lastname
    - List<Address> addresses
  }
}
