The main goal of OpenAIRE is to support the Open Access pilot, launched by the European Commission in August 2008. This Open Access pilot, which covers about 20% of the FP7 budget, commits researchers from 7 thematic areas (Health, Energy, Environment, Information & Communication Technology, Research Infrastructures, Socio-economic sciences & Humanities and Science in Society) to deposit their research publications in an institutional or disciplinary Open Access repository, to be made available worldwide in full text. OpenAIRE will establish underlying structures for researchers to support them in complying with the pilot through European Helpdesk System, build an OpenAIRE portal and e-Infrastructure for the repository networks and explore scientific data management services together with 5 disciplinary communities.
