Global Research Identifiers Database (XI-GRID)


The Global Research Identifiers Database collects information on research institutions and assigns them a unique identifier.

It draws on information from funding datasets, and claims over 90% coverage of institutions.

It records information on the nature of the research organisation, covering companies, education establishments, healthcare, non-profits, government and other entity types.

GRID also records parent-child relationships between entities, and 'related relationships' for cross-linkages.

It includes cross-linkages to a range of other identifier sources.
