It is every organization’s desire to incorporate best practice into its enterprise. This incorporation gives rise to the need to maintain information that could be viewed as complex. Managing this complex information poses a major challenge to the area of information management. This paper presents a framework for the incorporation of best practice and subsequent management of the resulting complex information. The paper also presents an approach to supporting this framework by using the ECA rule paradigm with an XML-based language, called AIM, for specifying and querying best practice and the complex information.
