GRID

Global Research Identifier Database, a legacy identifier and registry of research organisations originally operated by Digital Science, frozen to new records in 2021 and superseded by ROR, which seeded its registry from a deduplicated GRID snapshot.

Examples

Worked examples

  • Is an instance

    grid.4991.5 (legacy GRID for University of Oxford), now mapped to a ROR ID.

  • Is an instance

    A pre-2021 affiliation tag in an analytics database using grid.5335.0 for University of Cambridge.

Counter-examples

Looks similar, but isn't

  • Not an instance

    A newly created research institute in 2024 will not have a GRID record because GRID is frozen.

  • Not an instance

    A funder identifier from Crossref Funder Registry is not a GRID ID.

Editorial commentary

GRID identifiers take the form grid.NNNNN.X (e.g. grid.5335.0). GRID provided the first widely adopted open registry of research organisations and was used in Dimensions, altmetric platforms, and various CRIS systems. After ROR’s launch in 2019 and the transfer of curation to the community-led ROR initiative in 2021, GRID was frozen and Digital Science stopped issuing new IDs. ROR records carry GRID crosswalks so legacy GRID-keyed data can still be joined.
