TOGAF Business Architecture Metamodel Based On Enterprise Ontology Theory

It is an important goal for enterprise architecture to pursuit the coherence andcoordination of all aspects in the organization through the scientific organization de-sign, which can help enterprise to succeed about strategy reform and improve theadaptability of enterprises to increasingly competitive environment. Enterprise ar-chitecture, as the principles and guidelines, define the structure of each componentand the relationship between them and guide the enterprise how to change with time.Working about enterprise architecture relates to all aspects of the organization.Metamodel as a model of description model, is a standard of defining a model.In order to ensure the consistency of enterprise architecture, a scientific and accuratemetamodel is essential. Ontology is subjective word’s explain and reflect about ob-jective world. It can be shared by subjective. In order to ensure the common under-standing and awareness to enterprise architecture of people in organization and thesystem, it is necessary to add the semantic information to architecture metamodel andcarry on the ontological description.This paper focuses on the open group architecture framework (TOGAF), whosetop contribution is the architecture development method. However, its metamodelhave some shortcomings. To solve these problems, we redefined the entities and rela-tionships of enterprise business architecture metamodel. Meanwhile, we make a on-tological definition of metamodel entities and relationships through combining theenterprise ontology theory and architecture theory and using ontology Method–SBVR, which based on the facts. At last, we used this metamodel in a bank medicalmanagement system.
