| A [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definition]] describes the structure, meaning, and constraints of an information class at the platform-independent logical level. It does not represent an IDL structure, a Protocol Buffers message, a JSON Schema definition, an XML Schema definition, an Avro schema, an OpenAPI schema, a database table, an ontology class, a generated type, a file, or a wire-format payload. | A [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definition]] describes the structure, meaning, and constraints of an information class at the platform-independent logical level.
