From text to traceability: RRID integration in Europe PMC – Europe PMC News Blog

"Scientific articles are theoretically rich in details about antibodies, cell lines, model organisms, or software tools. However, these details are often poorly reported and remain locked in unstructured text, making it difficult, or impossible, to reproduce experiments. Mentions are often ambiguous, inconsistent, or difficult to track across studies. This is where Research Resource Identifiers (RRIDs) come to the rescue. RRIDs are unique persistent identifiers (PIDs) assigned to key research resources and are structured (for example, RRID:AB_572263) to transform a vague mention (like “anti-GFP antibody”) into something precise, traceable, and comparable across studies. Unlike plain text mentions, these PIDs are globally unique, machine-readable, and linked to curated metadata.

RRIDs are integrated into Europe PMC through the annotation platform. RRIDs provided by SciCrunch are associated with articles within the Europe PMC database, making them available through search, integrated into the SciLite annotations tool, and retrievable programmatically through the Annotations API. API access allows developers to retrieve and use RRID annotations linked to literature in Europe PMC in their own applications and researchers retrieve the data for analysis....

RRIDs can be searched within Europe PMC through the Advanced search tool. In the ‘Links to data records’ section, tick the ‘Find an accession or data DOI’ checkbox and then select the ‘RRID (Research resource identifiers)’ under the ‘Data type’ drop-down."
