Infrastructure for Open Science: analysis of the national coverage of persistent identifiers in Brazil

Resumo

The adoption of persistent identifiers is one of the pillars for the advancement of Open Science, as it promotes interoperability, traceability, and reproducibility of research. This article presents a quantitative analysis of the presence of persistent identifiers in CVs registered on the Lattes Platform, focusing on ORCID for authors and DOI for publications. More than 9 million CVs were analyzed, revealing that only 377,385 researchers had informed their ORCID. Regarding publications, of the 12.8 million publications in journals, 46.6% contained DOI; this percentage was significantly lower in articles published in conference proceedings (2.4%), book chapters (14.3%), and books (6.4%). The results point to the need for greater institutional and cultural incentives for the use of persistent identifiers, as an essential condition for strengthening Open Science in Brazil.
