In April 2025, we launched the metadata matching project, in order to add missing relationships to the scholarly metadata. We will do this by consolidating all existing and planned matching workflows, which enrich member-deposited metadata in Crossref. This unified service will result in a more complete research nexus. In this blog post, we share our latest milestone: developing and evaluating a strategy for matching funder metadata to Research Organization Registry (ROR) identifiers.
