The rapid development of digital technology and information networks now permits a broad and easy dissemination of digital works and other electronic information. However, once published, it is difficult to control access, usage, manipulation and distribution of digital materials. The ease of reproduction of electronic information raises the problem of Intellectual Property Rights (IPR). But beyond the necessity to ensure the protection of digital information and the associated rights owned by the work's originators and the various rights-holders, the need to have a full management of IPR is getting crucial. More and more, authors, publishers, fee-collecting companies, producers, distributors, etc., are looking for tools which are able to determine the utilisation conditions of their works and to provide them with information on the usage, in order to get the reward corresponding to the exploitation of their works and to better market them. Several projects have been initiated in order to meet the needs related to IPR management. In 1992, the European Commission launched under the ESPRIT Programme, the CITED project (Copyright In Transmitted Electronic Documents) with the objective of defining a global model for IPR management. CopySMART represents the industrialisation of the CITED model.
