OData Metadata in UI5

OData metadata in UI5 is the service description document exposed by an OData backend that describes the structure, entity types, and properties of the data available to an application. Developers use it in UI5 to drive XML templating, where an XML view is processed at pre-processing time against the metadata to generate data-bound views dynamically. This approach allows the UI to adapt to the shape of the OData service without hardcoding field-level details into the view definition.
