Sharing data and image processing tools in neuroimaging.

Research in neuroscience makes an extensive use of modern neuroimaging data. The ability to share such data as well as processing tools to analyze them becomes a key factor of success of future research. This paper reports about works carried out in the context of the Neurobase project, a collaborative exploratory action supported by the French Ministry of Research. The partners have studied the design of a system suitable for sharing heterogeneous data and image processing tools, according to a federated approach, based on a common ontology. A demonstrator has been implemented, providing basic services for querying data and launching processing tools distributed at several sites.
