Princeton Data Commons — Discovery
Princeton's research data repository, split into pdc_describe for deposit and description and pdc_discovery for the public portal at datacommons.princeton.edu/discovery. Both are Princeton-written (pulibrary/pdc_discovery, pulibrary/pdc_describe), and the discovery portal exposes an unauthenticated Blacklight JSON API. Datasets are addressed by DataCite DOIs under Princeton's own 10.34770 prefix and records carry ORCID identifiers. This is the slot most universities in this cohort fill with a Figshare or Dataverse tenancy; Princeton operates it themselves.
