Η μετεξέλιξη ενός αποθετηρίου κοινωνικών επιστημών: το παράδειγμα της Πανδήμου σε περιβάλλον Fedora.

The implementation of an institutional repository is a complex process of analyzing the needs of the academic institution that it serves, evaluating and selecting of software, documentation of establishing policies, valorisation of interoperability models and long-term preservation of its content. In the case of the Library of Panteion University, a framework is proposed for the development of the Digital Library "Pandemos", based on the choice of Fedora software for its installation and operation. The choice of Fedora software was based on its advanced management and representation of collections and objects, which in combination with its flexible architecture, it permits the integration of heterogeneous digital material (gray literature, photographical and historical archive, conferences material, journals, etc.), electronic submission of material, documentation and publication, further improvement and display of the content (SEO), application in multiple metadata formats, etc. This paper describes the stages of software selection, management and organization of collections and implementation by developing separate metadata import environments (editors), the applied standards of interoperability, the determination of policies for describing the material with the selection of metadata schemas. Furthermore, we indicate the main problems that were resolved in each stage of the implementation of the institutional repository, the steps followed to address them, collaborations developed with the involved staff members of the Library (computer engineers & librarians) and the degree of interdependence of their work. Finally, the uniqueness of the development of an academic Greek digital library in Fedora environment is presented, as far as the knowledge obtained and the prospects for the future.
