  We leverage the Open Research Knowledge Graph - a scholarly infrastructure
that supports the creation, curation, and reuse of structured, semantic
scholarly knowledge - and present an approach for persistent identification of
FAIR scholarly knowledge. We propose a DOI-based persistent identification of
ORKG Papers, which are machine-actionable descriptions of the essential
information published in scholarly articles. This enables the citability of
FAIR scholarly knowledge and its discovery in global scholarly communication
infrastructures (e.g., DataCite, OpenAIRE, and ORCID). While publishing, the
state of the ORKG Paper is saved and cannot be further edited. To allow for
updating published versions, ORKG supports creating new versions, which are
linked in provenance chains. We demonstrate the linking of FAIR scholarly
knowledge with digital artefacts (articles), agents (researchers) and other
objects (organizations). We persistently identify FAIR scholarly knowledge
(namely, ORKG Papers and ORKG Comparisons as collections of ORKG Papers) by
leveraging DataCite services. Given the existing interoperability between
DataCite, Crossref, OpenAIRE and ORCID, sharing metadata with DataCite ensures
global findability of FAIR scholarly knowledge in scholarly communication
infrastructures.
