DELOS - Deliverable 1.1.1 - WP 1: Survey on Peer-to-Peer Architectures, Grid Infrastructures, and Service-oriented Architectures for Digital Libraries

Second generation DLs have new requirements. Firstly, these requirements include the way to make data and specialized DL applications available to a large set of users by means of well-defined services. Secondly, the interaction between independent data/service providers (peers) within a network needs to be addressed. Finally, the computing and storage resources that are available in large networks have to be made available in an efficient and effective way by means of grid technology. We provide a survey in order to highlight whether and to what extent i.) service-oriented architectures, peer-to-peer infrastructures, and grid infrastructures can contribute to satisfy the requirements of these new DLs. This survey contains a detailed summary of state-of-the-art in the three architectural paradigms and lists current approaches that aim to exploit these architectures in DL Management systems and DL applications
