Retrieve the complete DBpedia ontology schema. Returns the entire ontology defining all classes, properties, and their relationships in the DBpedia knowledge base. This includes class hierarchies (e.g., Person → Agent → Thing), property domains and ranges, and datatype definitions. Use this to understand the complete structure of DBpedia data - what types exist, how they relate, and what properties are available. Essential for building comprehensive SPARQL queries.
