====== Model Construction Service Archive Page ======


Note that for all of the model construction services the CRUDE pattern applies where CRUDE is defined as:

  * C:  Create
  * R:  Retrieve (or Query)
  * U:  Update
  * D:  Delete
  * E:  Execute  (implies an executable model that is used to verify the completeness/correctness of the model under construction)

  * **Model Construction Services**
    * **Login**
      * Description:  Provide user/process credentials, returns a pointer to the session.
      * Service Signature:  SessionLink login (String userID,  String password)
      * Concept Model Element: User, Role, AccessControl
      * References:
      * Assumption:  The security (access control)  context for the Model Construction services is contained in the "Session"  created when the modeler authenticates themselves and initially accesses the model.   The credentials for the modeler are associated with the "Session" and not included explicitly in the Model Construction services themselves.   If an access violation occurs,  it is assumed that an exception is raised and the modeler is notified that access is not available.   The credentials and access control rules are determined by each organization or project.
    * **Logout**
