Never instantiated directly: a harvest types the concrete kind, and a viewer shows that kind rather than this parent.\n\nWHY THE PARENT EXISTS. Three properties need exactly this set as their scope: storedIn from a Data Object, hasField and its inverse livesIn, and dependsOn. Without it each would have to be tripled, once per concrete kind, and the checks would go with them.\n\nWHY THE NAME CHANGED. It was PhysicalRelation, from Codd, where a relation IS a table. In an ontology \"relation\" reads as a property, and the word locks the class into the tabular world. A Neo4j node label, a Mongo collection and a Kafka topic all carry fields; none is a relation.\n\nEXTENSION POINT for non-tabular storage. Nothing at Pernod Ricard is non-tabular today, so no such class is declared -- four terms were deprecated in v1.2 precisely because nobody instantiated them. The day a graph enters scope, the insertion is additive and touches no instance, because subClassOf is transitive:\n\n pr:Dataset rdfs:subClassOf pr:DataStructure .\n pr:Graph rdfs:subClassOf pr:DataStructure .\n pr:BaseTable rdfs:subClassOf pr:Dataset . # instead of DataStructure\n pr:inSchema rdfs:domain pr:Dataset . # instead of nothing\n\nExisting BaseTable assertions stay DataStructure by entailment, every shape targeting DataStructure keeps working, and storedIn does not move.
