Economic framework for pricing and charging in digital libraries
Abstract
We consider commercial Digital Libraries as information economies consisting of several players: authors and publishers who create and sell their collections, suppliers (e.g. computer systems) who provide information storage, indexing and access services, information-agents who provide searching and presentation services, and users who request for services. In such an economic framework, one can envision suppliers and information-agents competing to provide services for information storage, searching, access and presentation. In providing such services, several issues arise; among them are socio-economic and cultural aspects of pricing information objects and Quality of Service (QoS) to access and view these objects. These issues play an important role in allocating resources such as processing time, network bandwidth and buffers, memory, cache and I/O, which are distributed (and owned) among various players in the economy. Using this framework, we present the interactions among the players, service models, pricing and charging/billing mechanisms, and corresponding implementation issues in large digital libraries.
