This post describes the NFDI4BIOIMAGE Knowledge Graph (N4BIKG). Many aspects of this project are still very much in the flow including a consensus on which ontologies and terms to employ, how to define various namespaces and much more.
The N4BIKG is accessible through a SPARQO endpoint at https://kg.nfdi4bioimage.de/N4BIKG/sparql. The dataset is split into four named graphs:
PREFIX : <https://nfdi.fiz-karlsruhe.de/ontology#>
PREFIX n4bikg: <https://kg.nfdi4bioimage.de/n4bikg/>
PREFIX nfdicore: <https://nfdi.fiz-karlsruhe.de/ontology/>

As a convenience, the default graph is the union of all named graphs.
