A Method For Semantic Description Of The Enterprise Architectural Domains Based On To GAF Framework
The growing proliferation of large organizations and consequently the need for design and development of complex information systems alongside the emergence of information systems for specific purposes highlighted the importance of organizations’ flexibility against external pressures such as business changes, missions, organizational structures, and rapid technological changes which express need for an inclusive and comprehensive entity called Enterprise Architecture. On the other hand, the increasing prevalence of business systems on the basis of information technology arises need for apprehensible modelling in human – machine interaction. In this regard, description and modelling of enterprise architectural domains is significant for a better understanding of the proposed architecture for man and machine. Modelling has always increased the level of perceptual analysis although it can still have challenges. These challenges appear especially when the modelling is not completed and it will be incompatible because of the separation of understandable modelling for human and machine. Many of these challenges can be overcome by adding meaning to common models. The main goal in this article is presenting a method to describe the enterprise architectural domains for better understanding of the proposed architecture semantically. Focusing on the fact that business architecture is one of the most important domains of Enterprise Architecture and has a great impact on the other domains of Enterprise Architecture, and if it is possible to describe its semantic and precise syntax, it is worth a lot. We use the proposed ADM concept in the TOGAF reference model along with the ArchiMate modeling language. We use ontology and semantic annotation to add meaning to syntactic description. Considering that one of the most important parts of any enterprise architecture is its business domain, the WSMO and Goal Specification concept have been used to describe business processes. Finally, the description created in the WSML language to ensure proper semantic description is transformed into the official language B.
