CoARA Boost CF1 - FEDRA - Final Technical Report: proof-of-concept pipelines for Porto@IRIS and OpenAlex metadata linking (Task 1. RP M6 – M12)

This technical report documents the final deliverable of the FEDRA project, Task 1, which aims to support the integration of the Politecnico di Torino research information system with external open scholarly infrastructures within a FAIR-aligned institutional metadata lake. We describe a proof-of-concept pipeline to reconcile author and work records stored in institutional databases with corresponding entities in OpenAlex, combining identifier-based linking (ORCID/DOI) with similarity-based matching when identifiers are missing or inconsistent. We report validation experiments on curated samples and provide summary statistics on matching performance. Finally, we compare the availability of works across OpenAlex and Scopus for a selected subset of researchers, discussing observed coverage gaps and recurrent edge cases relevant for institutional metadata enrichment and quality control.
