Using the TOGAF 9.1 framework, we would use concepts of the Metamodel. The content metamodel uses the terminology discussed within the TOGAF ADM as the basis for a formal metamodel. 6 Platform Specification The final building block of the near term system vision is the platform specification.This is basically the complete definition of the metadata interoperability and interchange Not very much in the core metamodel. The paper presents an evolved metamodel that has its origins in GERAM 1.6.3 but takes into considerations the needs of evolution of EA standards, including ISO 15704:2000 and ISO 42010:2000 . The following core terms are used: Actor: A person, organization, or system that is outside the consideration of the architecture model, but interacts with it. These render models that conform to the older version of the metamodel non-conformant to the newer version. It articulates the structure of an enterprise in terms of its capabilities, governance structure, business processes, and information. It's not really about the model-types or models that could be constructed via such a metamodel - other than that we want this metamodel to support any type of model that would be needed in EA or strategy or the like.

Architecture Realization entities capture change roadmaps showing transition between architecture states and binding statements that are used to steer and govern an implementation of the architecture; A more detailed representation of the content metamodel is shown in Figure 30-4. In this paper, we presented a novel approach to learn metamodel domain concepts using a RoBERTa pre-trained language model architecture based on tree representations of the metamodels. Material can Realise Business Object. If you are unfamiliar with this Class diagram notation, you may want to read Chapters 5 and 6 first, and then come back here. ArchiMate example views introduced here are organized into a layered framework according to ArchiMate standard (see ArchiMate version 3.1 here ). So now, how do we build that traceability? The content metamodel provides a definition of all the types of building blocks that may exist within an architecture, showing how these building blocks can be described and related to one another. The Architecture Capability defines the parameters, structures, and processes that support governance of the Architecture Repository. Each successive level is labeled from M 3 to M 0 and are usually named meta-metamodel, metamodel, class diagram, and object diagram respectively.

Those who are fans of the metamodel see a good metamodel as one of the major foundations for an effective EA practice. Furthermore: The foundation of the NAF is the NATO Architecture Framework Metamodel. It tries to be "methodology agnostic." To do that, we define a generic pseudo-methodology which can then be mapped to other architecture . The combination of reference architecture, the metamodel, and the twelve modeling principles and practices for architectural knowledge management in IT services (addressing the extended scope of both presales design activities and architecture design on projects) is the core contribution of this paper. - A metamodel is a model of a modeling language. Although TOGAF is quite careful with defining the basic and core concepts in both Chapter 2 and Chapter 3, the definition of the key concept "Enterprise Architecture" is remarkably missing. Entity types are analogous to tables in database theory or to classes in object-oriented theory. • A model that describes how and with what the architecture will be described in a structured way.
