Issues of Modeling Web Information Systems Proposal for a Document-centric Approach

There have been already several researches on modeling various aspects of WIS. In our approach, we concentrate on the organizational and process modeling and we put the emphasis on documents that represent the information of enterprises in the form of unstructured and semi-structured documents. The assembly of documents reflects implicitly or explicitly the organization of enterprise and the network of business processes and the activities and tasks within processes. The documents represent at the same time the organizational 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.
