A collection of shapes that are part of a GraphQL schema. Includes declarations about which shapes shall be exposed/published by a GraphQL service. The set of public node shapes consists of all values of graphql:publicShape, all values of graphql:publicClass and their subclasses, all node shapes from any namespace graphql:publicNamespace, minus any explicitly excluded shapes via graphql:privateShape. An RDF graph may contain multiple GraphQL schemas, each providing a different API or view on the underlying data. GraphQL services can include each other using owl:imports. To simplify common usage patterns, owl:Ontology has been marked as a subclass, so that all Ontologies are also graphql:Schemas once this graphql namespace is imported.
