EAI — Missing specification for EAISubscriptionTable

  • Key: EAI-82
  • Legacy Issue Number: 4971
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    Document: UML Profile and Interchange Models for EAI
    Sections: (EAISubscriptionOperator) and (EAIPublicationOperator)

    The concept of a subscription table is discussed in Sections and as if the table was a reified entity in the metamodel (and, in fact, the class name "EAISubscriptionTable" is used in Section However, Figure 6-35 in Section and Figure 6-40 in Section show, instead, the subscription table defined as individual associations from EAISubscriptionOperator and EAIPublicationOperator to EAISubscription. Not only does this define dynamic state rather than metadata, it defines DIFFERENT dynamic states for the two operators, rather than the single shared table that is necessary.

    Remove the "subscriptionTable" association (between EAISubscriptionOperator and EAISubscription) and "currentSubscriptions" association (between EAIPublicationOperator and EAISubscription) from Figures 6-35 and 6-40. Instead, define an EAISubscriptionTable class as a child of EAIResource and put constraints on EAISubscriptionOperator and EAIPublicationOperator that each has a exactly one resource, which is and EAISubscriptionTable. The class EAISubscription (Figure 6-37) is also no longer needed as part of the metamodel.
