The European Grid Initiative (EGI) represents a move to provide a sustainable distributed computing infrastructure to support European research activity. The EGI model, based around the federation of National Grid Initiatives (NGI) coordinated by a small central organisation EGI.eu, has been developed through extensive community consultation within a multi-year design study. The focus of this presentation will be the implementation of the EGI model (as described in the EGI Blueprint) that is being prepared for submission to the EC for funding. It will detail the envisaged structure of the EGI, the expected contributions of the NGIs, and the relationship that EGI will have with its user communities and its software providers. The relationship between EGI with other European projects and infrastructures will be described, and the interactions EGI expects to have with other projects and infrastructures around the world.
