        Towards a Long Term Agenda for Digital Library Research 45m
        Digital Libraries constitute a relatively young scientific field, whose life spans roughly the last ten years. Despite its young age, the field has made a long journey from its initial conception to the present state of the art and has reached a level of maturity that warrants taking stock of its course so far and paving a path for the immediate and long-term future. This talk analyzes the recommendations of several activities that were initiated by the DELOS Network of Excellence, especially of the last DELOS Brainstorming Workshop in July 2004. It identifies the main directions that future work on Digital Libraries should follow, emphasizing the design of systems that are person-centric, collaborative, distributive, generic, and appropriate for a wide variety of applications.

        Peer-to-Peer Architectures, Grid Infrastructures, and Service-oriented Architectures for Digital Libraries 45m
        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. In this talk, we address the question whether and to what extent service-oriented architectures (SoA), peer-to-peer (P2P) systems, and grid infrastructures can contribute to satisfy the requirements of these new DLs. This is based on the results of a DELOS WP1 (DL Architectures) survey on SoA, P2P, and grid.

        Concepts of Grid Computing 45m
        A Grid is “an infrastructure that enables flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions and resources” (Ian Foster and Carl Kesselman). This talk explains what this means. It explains how by a single log-on, users are authenticated and authorised to use computers in other organisations for computation or data access. The roles of virtual organisations, the supporting operations services and Certificate Authorities are described. The history of grid computing is outlined: from early prototypes towards e-infrastructure that provides services for many research communities.

        Grid middleware 45m
        The many concurrent developments of grid middleware have created what is sometimes termed a middleware "ecosystem" - some developments are cooperative, and others are alternative solutions to the same problems. The talk describes the most commonly used middleware packages: Globus, Condor, VDT. It describes how the current LCG-2 / EGEE-0 production service builds upon these. Focus then turns to middleware that provides data services including SRB, OGSA-DAI and the GridFTP protocol.

        The EGEE project: its context, goals and status 45m
        The Enabling Grids for E-sciencE (EGEE) project is funded by the European Commission and builds on recent advances in grid technology to develop a service grid infrastructure which is available 24 hours-a-day. This talk outlines the context, goals, and activities of EGEE.

        GILDA demo 30m
        GILDA (Grid Infn Laboratory for Dissemination Activities, is a virtual laboratory for demonstration and dissemination purposes. GILDA consists of the following elements: * the GILDA Testbed: a series of sites and services on which the last version of the INFN Grid middle-ware (fully compatible with LCG middle-ware) is installed; * the Grid Demonstrator: a customized version of the full GENIUS web portal, jointly developed by INFN and NICE, from where everybody can submit a pre-defined set of applications to the GILDA Testbed; * the GILDA Certification Authority: a fully functional Certification Authority which issues 14-days X.509 certificates to everybody wanting to experience grid computing on the GILDA Testbed; * the GILDA Virtual Organization: a Virtual Organization gathering all people wanting to experience grid computing on the GILDA Testbed; * the Grid Tutor: based on a full version of the GENIUS web portal, to be used only during grid tutorials; * the monitoring system: a versatile monitoring system completely based on GridICE, the grid monitoring tool developed by INFN; * the GILDA mailing list:, also archived on the web here. The demonstration shows how to do grid computing using the GILDA dissemination grid testbed and the GENIUS grid portal developed by INFN and NICE srl in the context of both the Italian INFN Grid Project and the European EGEE Project.
