Dataverse is open source research data repository software that has supported distributed metadata for a long time and is increasingly supporting distributed data.
DataLad-Registry is a service that maintains up-to-date information on over ten thousand datasets, with the collection expanding as more datasets are added.
We present an ecosystem consisting of NeuroBagel, a distributed and scalable approach based on semantic web technologies for harmonizing and sharing phenotypic and neuroimaging variables with a DataLad backend, and NiPoppy, a specification for MRI processings to integrate derived data and curation information.
