The BELIEF Project is a Coordination Action funded by the European Commission in the context of the FP6 and FP7 Programmes. It aims to create a platform where e-Infrastructures providers and users can collaborate and exchange knowledge, ensuring that e-Infrastructures are developed and effectively used worldwide, filling the gap separating the e-Infrastructures providers from the users, and thus contribute to the emergence of a competitive knowledge-based economy. To create this synergy among multi-disciplinary communities, BELIEF created a one-stop-shop providing a Portal and a Digital Library with a huge number of e-Infrastructures open access publications. The Digital Library offers uniform access to multimedia documentation providing continuously updated information on e-Infrastructures-related projects, initiatives and events. The contents are harvested from different sources, such as projects web sites, repositories and databases. The DL - implemented on top of the OpenDLib Digital Library Management System - provides services to support the submission, description, searching, browsing, retrieval, access, preservation and visualization of multimedia documents. Although designed to meet the needs of the e-Infrastructures community, the technology adopted by BELIEF can be easily adapted to meet the information and collaborative needs of other scientific communities.
