v5.13.0 Release Notes

Today we released Context Mapper 5.13.0. This is a minor release containing the following changes:

• A Quickfix allows users to create Value Objects (VO) for ID attributes (in case you have attribute like String customerId, the Quickfix suggests to extract a VO).
  • We will implement more Quickfixes in future releases (this was a first architectural spike).

• Grammar change: Subdomains can refer the features (use cases or user stories) they support. Example:

  /* Syntax example for Subdomain that supports specific user requirements: */
  Domain Insurance {
    domainVisionStatement = "Insurance domain vision statement ..."
  
    Subdomain CustomerManagementDomain supports CreateCustomers, CreateCustomerAddresses {
      type = CORE_DOMAIN
      domainVisionStatement = "Subdomain managing everything customer-related."
  
      Entity Customer {
        String firstname
        String familyname
      }
    }
  
  }
  
  UserStory CreateCustomers {
    As an "Insurance Employee"
      I want to "create" a "Customer" with its "firstname", "lastname"
    so that "I am able to manage the customers data and offer them insurance contracts."
  }
  
  UserStory CreateCustomerAddresses {
    As an "Insurance Employee"
      I want to "create" an "Address" for a "Customer"
      I want to "update" an "Address" for a "Customer"
    so that "I am able to manage the customers addresses."
  }
  

  • The grammar documentation for Subdomains can be found here.
  • This feature allowed us to improve the OOAD transformations, since we can now backtrack which features a Subdomain or Bounded Context implements.
• The OOAD transformation for Step 3 (derive Bounded Context from Subdomain) has been improved:
  • Parameter and return types actually include the entities are not abstract types.
  • We generate Value Objects for IDs now.
• The following OOAD transformations can now be applied multiple times without producing an error or empty file:
  • Derive Frontend and Backend Systems
  • Split System Context Into Subsystems
• The graphical Context Map generator user interface in Eclipse persists the configuration of the user (so that the dialog shows the same values at next generation).
• The generic text file generator (based on Freemarker) suggests an ouput filename on the dialog in Eclipse (so that you have to change the file extension only).
• Change in MDSL generator: The generator produces contracts for all Bounded Contexts now, even if they are not an upstream context in an upstream-downstream relationship.
  • Sometimes you just want to generate the contract without specifying the client Bounded Contexts (downstreams).
• The following Architectural Refactorings (ARs) are now supported in Visual Studio Code:
  • Split Aggregate by Entities
  • Split Bounded Context by User Requirements (Use Cases and/or User Stories)
• The JDL template to generate Microservice applications with JHipster has been changed so that API-first development with Open API specifications is enabled for all generated microservices.
• Changes in MDSL generator:
  • The “Aggregate” suffix is no longer added to the endpoint names.
  • The “IPA” keyword at the end of the contracts is no longer generated (is optional in MDSL).
  • The latest MAP decorators supported by MDSL are respected by the generator.

As always, if you have any issues or other feedback, please let us know.
