NIDM is the Neuroimaging Data Model.
It’s a project I started within the neuroimaging data sharing task force at INCF
a while back, and it’s a project that aims to describe derived data from
analysis packages such as SPM, FSL, AFNI and others In such that you have the full
provenance of what has been done to the data within that model. So those
packages will be writing that files that describe exactly what
has been processed using those data. So it’s a very interesting and very
ambitious project stemming from INCF.
