Framework Programme 7 (2007-2013) Research infrastructures projets D4Science-IID4Science-II Summary: D4Science-II aims at developing technology to enable interoperation of diverse data e-Infrastructures that are running autonomously, thereby creating e-Infrastructure Knowledge Ecosystems that can serve a significantly expanded set of communities dealing with multidisciplinary challenges. The D4Science-II ecosystem will initially include, among others, the GENESI-DR and DRIVER repository e-Infrastructures, and important thematic repositories maintained by international Project acronym: D4Science-IIorganizations, e.g., INSPIRE and AquaMaps. By exploiting the resources made Project n°: RI-239019available by the interoperable e-Infrastructures, the project will also create Virtual Research Environments (VREs) that will offer significantly enhanced services to Project type: CP-CSAscientists operating in different areas, e.g. biodiversity, fisheries and aquaculture resources management and high energy physics, without incurring high development Start date: 01/10/2009and maintenance costs.Duration: 24 monthsObjectives: D4Science-II constitutes a continuation of the DILIGENT and D4Science Total budget: 5 442 904 €projects.
