The INCF has developed a data file sharing system called Dataspace. The system can be used to share unstructured data between investigators and with the world. For neuroimaging data hosted on Dataspace, it would be valuable to have an XNAT frontend to organize and distribute the data to users, computing resoures, etc. The project would develop a "crawler" that crawls through dataspace to identify neuroimaging data sets, extracts relevant metadata and then posts it to XNAT. It could be engineered to discover resources or it could be directed by a user to execute on a specified location in Dataspace.
Interested in working on this:
Dan Marcus, Christian Haselgrove, Nolan Nichols, other INCF data sharing participants
