To embed the wider importance of building a connected infrastructure for open science, the technical requirements for a repository to be compliant with Plan S include each funded deposited work having its own persistent identifier. For a Version of Record this will typically be supplied by the publisher (most often in the form of a DOI). In this presentation we will discuss the technical and policy considerations of how to add persistent identifiers to Author Accepted Manuscripts. This ensures that they are also fully available for discovery and citation to participate as first order participants in the open research ecosystem.
