    rdfs:comment "The Ocean InfoHub (OIH) federated metadata handling system relays the metadata PIDs (given to JSON-LD records) from our partners. The PID services used are diverse, including PURLs run by trusted and sustained organisations (e.g. OBO Foundry), DOIs, W3IDs, and IDs issued by trusted aggregators (e.g. OBIS). Not all metadata records integrated into our knowledge graph are assigned PIDs, a scenario we are gradually changing now that metadata records exist for use in Ocean InfoHub and ODIS" ;
