The present paper briefly describes the development of a funder repository aiming at the dissemination, reuse and preservation of digital material of diverse types, providing an enhanced user experience, which was produced under the auspices of large scale (multi-billion Euros) funding programmes of the Hellenic Ministry of Education (co-financed by the European Union). This involved the handling of a wide range of content, like (among others) educational material, books, peer-reviewed scientific articles, conference proceedings, theses, videos and studies/reports. The DSpace platform has been selected and used for the implementation of the repository and fulfilled the challenging requirements at hand, for example the heterogeneity of material; several DSpace extensions were also developed to assist both the back-end procedures for cataloguing and digital file processing as well as providing an enhanced end user experience. The project has been successfully completed and the system is publicly available since spring 2011 at http://repository.edulll.gr.
