Extending Hypertext Conceptual Models with Process-Oriented Primitives

Web conceptual modeling is a young discipline, which is gaining popularity among Web developers and CASE tool vendors. However, most conceptual models for the Web proposed so far are an evolution of hypermedia models, and pay attention mostly to the specification of data structures and navigation primitives. As the Web becomes a vehicle for implementing B2B applications, the need arises of extending Web conceptual modeling from data-centric applications to dataand process-centric applications. This paper presents a pragmatic approach to incorporate classical process modeling primitives within a Web modeling framework and comments on the experience gained applying the resulting methodology to an industrial case.
