Abstract
This report is an introduction to business models in use on the Internet and their applicability in the Renardus context. The report has five main strands. It first attempts to define what business models are and outlines some popular business models in use on the Internet, both commercial and non-commercial. A second section includes examples of business models used by other services in the cultural heritage sector. The report then takes a brief look at the business models of existing Renardus Data Providers, both gateways and brokers. It then describes some business models that could be adopted by the Renardus Consortium to help develop a sustainable service.
