Current research activities in the area of trading digital products usually focus on specific legal or technical problems, neglecting the underlying
business models and their implications on retail information systems. There is a need for a framework in to order the structure the diverse research efforts. Within the dissertation retailing of digital products is
positioned within the wider field of electronic commerce. Then business models for procurement and distribution of digital products are established. The Retail-H-Model, a framework for retail information systems
originally developed for traditional retailing, is used introduced as a structural framework for dealing with digital product retailing issues. All underlying functional models are examined and adapted in order to
fulfil the requirements of retailing digital products. The result of this work is first of all a roadmap for the process of designing retail information systems dealing with digital products and secondly a research
map in which ongoing research activities can be placed..
