Editorial commentary

Open infrastructure includes services that the scholarly community depends on: identifier services (DOIs via Crossref, ORCID), open citation graphs, preprint servers, repositories, persistent data archives and review platforms. The Principles of Open Scholarly Infrastructure (POSI), articulated by Bilder, Lin and Neylon in 2015 and updated in 2020, identify three dimensions: governance (community representation, transparent decision-making), sustainability (clear revenue model, mission consistency, transparent financials, contingency plans) and insurance (open source, open data, available data, patent non-assertion). POSI-aligned infrastructures include Crossref, ROR, DataCite, DOAJ and OpenCitations.
