The open-data portal for Global, connected live in Vizzie — browse its datasets and turn any of them into a map or chart.
World Bank Data Catalog (global development data) is the open-data portal for Global. It runs on World Bank Open Data, an open-data platform. You can browse it directly at ddh-openapi.worldbank.org.
Licences here are declared per dataset via Portal-wide CC-BY 4.0. A machine-readable summary of the licence mix isn't available yet, but Vizzie surfaces each dataset's declared licence (or notes when none is given) as you browse — remember that an undeclared licence is not the same as public-domain or free-to-use, so check before you reuse.
World Bank Data Catalog (global development data) doesn't expose a machine-readable breakdown of who publishes what, so there's no reliable publisher ranking to show here. Vizzie still surfaces each dataset's own publisher as you browse.
