OData CSDL Vocabulary Structure (Term, ComplexType, TypeDefinition)
OData metadata annotations are structured pieces of additional information embedded in OData metadata documents that describe the capabilities and behavior of a service. Developers read these annotations to understand how to interact with an OData service, such as discovering supported operations or UI hints. Vocabularies provide a standardized set of terms used to express these annotations consistently across OData metadata documents.

Prerequisites
- Concept OData Annotations and Vocabulary Terms The concept name is missing or undefined, so a precise definition cannot be produced. Based on the available sources, the closest identifiable concept is **OData Annotations**, which are metadata constructs based on vocabularies that developers attach to OData service definitions to describe the behavior and presentation of data. Developers use OData annotations in SAP Fiori applications to configure UI elements — such as List Report pages — and to control how data is interpreted and displayed, without modifying the backend service itself. You can learn more in the [Working With OData Annotations](https://ui5.sap.com/#/topic/8b55ead17bd54c56b5597977fbf4b123) documentation.
- Concept OData Metadata Document Structure and Navigation A structured document that describes the data model of an OData service, including its entity types, properties, and relationships, as well as optional annotations that provide additional semantic meaning. Developers read OData metadata documents to understand the structure of a service's data before consuming it, and use vocabularies to interpret the standardized annotations applied to that metadata.
- Concept EDMX and CSDL XML Structure The concept name was not provided, so a precise definition cannot be written. Please supply the concept name so it can be accurately defined based on the available sources covering OData metadata documents, OData standards resources, and OData vocabularies.
