Facet of Modeling Web Information Systems from a Document-Centric View

Abstract

The modeling of Information Systems in general, and Web Information Systems (WIS) especially, is a permanent issue so that there have been already several attempts and proposals for representing various facets of WIS. In our proposed approach, we focus on the organizational and business activity modeling and we concentrate on documents that represent the information of enterprises in the form of unstructured and semi-structured documents. The compilation of documents mirrors implicitly or explicitly the structure of enterprises, the interrelationship of business processes, and activities and tasks within processes. The documents represent, at the same time, the system roles along with tasks and activities. Our modeling approach concentrates on the co-existence and co-operation of documents and activities of business. The Story Algebra, or more generally the process algebra approach provides a formal framework that promises a formal describing method for modeling precisely the event triggered processes coupled with data in document format within an Enterprise Architecture Framework.
