A Digital Library Management System for Grid

Huge amount of data can be stored on Grid Storage Elements, but few tools are provided by the EGEE gLite middleware to easily search and retrieve files a user is looking for. File catalogues can help organizing data in hierarchical structures, but they do not provide a way to describe file contents. On the other hand, we have Metadata Services, that can be used to attach additional information to files, but this services are not so easy to use by non-experienced people. In this paper a easy-to-use system to handle digital assets stored as grid file is presented. Such system is called gLibrary. It offers a intuitive interface that allow users to browse and filter the available entries, as well as to retrieve or upload a file by copying it from one of the Storage Elements (SEs) into user's local machine, or vice-versa.
