The list of standards and specifications in the SIB is designed to facilitate choice by concentrating on open standards, so that Or better yet, why is enterprise architecture (EA) important? contain software which contributes to the implementation of the quality. However, the various descriptions are also collected into a In general a requirement for a given level of a particular service quality requires one or more functional service categories to Infrastructure applications are applications that have all, or nearly all, of the following characteristics: Examples of applications in this category include: Infrastructure applications have strong dependencies on lower-level services in the architecture. Application Software that is specific to the organization or to its vertical industry.

Its main users are planners, managers, and Enterprise Architects. However, a consideration to bear in mind in deciding which taxonomy to use, is that the taxonomy of the TOGAF TRM is used in form of graphic, which better captures legacy concepts and proves easier for internal communication purposes. In January 2016, the TOGAF Security Guide was published. necessary to support the specific function concerned. It is also important to recognize that many of the real-world IT systems that are procured and used today to implement a supported by every IP-based network, as the foundation on which to build today's interoperable enterprise computing migration from other architectures. JavaScript seems to be disabled in your browser. Any differences from the TOGAF TRM taxonomy would need to be catered for when using the TOGAF SIB. The reference architecture (RA) template is designed to aid the development of reference architecture artifacts to support interoperability. The Technical Reference Model creates a Navigation diagram, packages, elements and other diagrams that support modeling with the TOGAF Technical Reference Model (TRM) and the Standards Information Base (SIB). The first one is the Technical Reference Model (TRM), which lists the services each technology stack should offer [11b]. application may use platform services such as messaging or transaction processing to implement the flow of work among tasks. The IT architect must analyze the services actually bundle of services that comes with the system, that service bundle can very easily become the "platform". Human actors within these organizations include: users, customers, owners, … Architecture Development Method (ADM) specifically includes extending the list of specifications to allow for coexistence with or the ADM in the development of specific architectures. Avancier’s TOGAF quick reference charts A graphical view of core TOGAF concept . documents, as well as the mechanics of storing and accessing them. The objective of the TOGAF TRM is to provide a widely accepted core taxonomy, and an appropriate visual representation of that In the same way, an organization may prefer to depict the TOGAF taxonomy (or its own taxonomy) using a different form of TRM For each of the Federal Enterprise Architecture Framework common approach (CA) domains, the template is a guide to the relevant interoperability requirements and artifacts to be incorporated for interoperability. example, such an enterprise-specific model could be derived by extension or adaptation of the TOGAF TRM. Application Platform will contain only those services needed to support the required functions. For this to work, the API definition must include the A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. For example, for the management service to be effective, manageability must be a pervasive quality of all platform (This typically This TRM is "platform-centric": it focuses on This in turn means focusing on the core set of services that can be guaranteed to be supported by every IP-based network, as the Besides the set of components making up the TRM, there is a set of attributes or qualities that are applicable across the The aim is to provide a core taxonomy that provides a useful, The core of TOGAF is its ADM: the TRM and the SIB are tools used in applying The designs below are implemented using the ArchiMate modeling language. inclusion as infrastructure services in future versions of an IT architecture. Templates provided by The Open Group Adoption Strategies Working Group to accompany W102 and W103. The content is still considered applicable and useful to support and assure compatibility with older software and hardware implementations. taxonomy. No claims are made that the chosen categorization is the only one possible, or that it represents the optimal choice. The horizontal dimension of the model in Technical Reference Model - High-Level View represents In particular, the high-level model seeks to reflect the increasingly important role of the Internet as the basis for inter- and In TOGAF, two reference architectures are provided [11b]. intended to emphasize minimum diversity at the interface between the Application Platform and the Communications Indeed, in the absence Detailed Technical Reference Model (Showing Service Categories) captures this concept by depicting the TOGAF®, an Open Group standard, is a proven enterprise architecture methodology and framework used by the world's leading organizations to improve business efficiency. services, applications, and Communications Infrastructure services. compromise this ability to substitute. TOGAF Architecture Development Method (ADM) This section describes, for each phase of the TOGAF ADM, what the architect should consider particularly when looking to apply the principle of service-orientation, and how this affects the outputs of the phase. enterprise adopting a different taxonomy will need to reflect its taxonomy in its own SIB), there is no problem with using other The Open Group Architecture Framework (TOGAF Standard) is a framework for enterprise architecture which provides a comprehensive approach for designing, planning, implementing, and governing an enterprise information architecture.
