psych-DS is a community project (originating at the SIPS @improvingpsych conference) that aims to standardize #dataset formats and #metadata for psychological science.
They have reached a big milestone: the initial release of the Psych-DS structure has been fully implemented as a validator (essentially a "spellcheck" that determines if a dataset matches the standard)
