An overview of the knowledge discovery meta-model

Abstract

Modernization of existing software systems is expensive and not always successive process that involves many challenging activities. In order to support these activities, the Object Management Group within the Architecture-Driven Modernization initiative proposes a number of standard representations of views on existing software systems. The Knowledge Discovery Meta-model plays the fundamental role in this set of representations as it defines common concepts of software assets and their operational environments. This paper addresses issues related to the extraction of knowledge from the software assets and the representation according to the Knowledge Discovery Meta-model in order to abstract the business logic implemented in the system. It observes that although this meta-model minimizes the effort required to obtain representation, it has several drawbacks that limits its capability to express domain specific knowledge. It is believed that this paper will enable researchers and practitioners to get a better understanding of this kind of representation, prepare for the modernization activities, and provide a basis for the further research.
