Studying infrastructures for Open Sience Teresa Gomez-Diaz (CNRS/LIGM), may 2015 Our goal is to study the main features in the design and construction of infrastructures for open access. Infrastructures have usually three main components: teams and their governance, proposed services, servers and interfaces to make services available. They also have funders and stakeholders to provide resources, a target public, a problem to be addressed. Infrastructures for open science provide visibility and accessibility to the research production, mainly for articles, software and data. By linking the research software and data that have been part of the building of a research result, they increase the reproductibility of research and its free/open access. In this study we propose a somehow "ideal" but flexible infrastructure to improve access to, and dissemination of, the open science production. In this infrastructure, designers, funders and decision makers can decide the level at which services may be delivered to target scholar and research communities, which are the required resources. They participate to the governance and the organization of the teams needed to run the services, to build a community and to ensure a good level of of collaboration among participating members. In this way we study the main components in the design of infrastructures for open science and their interactions.
