INRiM adopts the principles of Open Access to scientific literature and promotes the free dissemination of research results produced by the Institute.

The Institute's Policy on Open Access to scientific publications, effective from 1 January 2021, was approved by the INRiM Board of Directors at its meeting on 13 October 2020.

The document reiterates the importance of enhancing the accessibility of research results in the form of publications, data and open-source software to create Open Science that promotes responsible and collaborative research. As a result, opportunities for analysis, validation and reuse of scientific research results are multiplied, and the scientific and cultural heritage is enhanced and preserved.

The Institute uses an institutional repository, METRICA (METRology Institutional CAtalog), for policy implementation. The operational management of METRICA is carried out through a module of the Institutional Research Information System, the Research Catalogue - IRIS.

INRiM recognises the fundamental importance of data produced during research activities as a prerequisite for any valid scientific result. Therefore, it recognises the importance of data's proper management for maintaining the values of quality and integrity of scientific research and is committed to applying the highest standards for their collection, storage, preservation and publication.

To this end, INRiM has adopted a policy on research data management (RDM) to support researchers' activities to maintain a sustainable research environment.
