Session outlinebull Introduction to OpenAIREbull Technical Conceptsbull Hands on Session
Open Access Infrastructure for Research in Europe
Need for digital research infrastructures for all kinds of research outputs across disciplines and countries
bull comprises a database of all EC FP7 and H2020 funded research projects publications datasets
bull manages scientific publications and associated scientific material
bull aggregates Open Access publications and links them to research data and funding bodiesbull supports the Open Access principles via national helpdesks and comprehensive guidelines
httpwwwopenaireeu
OpenAIRE Services
OpenAIRE focuses onbull Workflows and processes of scholarly communication rather than resources
bull Research data and other research outputs rather than only publications
bull The links between considered entities
bull Relationship of European OA infrastructures with other regions of the world
enables search discovery and monitoring of the publications and datasets resulting from gt100k research projects gt17m publications
Interlink to other databasesSupport researchers by answering interesting queries
The OpenAIRE vision
bull Data about scientific events emergence of scientific topics
bull Data about people affiliation impact of certain research
Use cases
bull Research managers use new indicators for measuring the quality bull Policy makers get a quick overview of the findings and projectsbull Researchers find comprehensive citations list research movement between
communitiesorganizationsbull Reviewers get a quick overview of the field covered by the paper or dataset under review
