7. Open service metadata document

    • OData defines a metadata format based on the Entity Data Model in XML (edmx).
    • To access a service’s metadata document use the $metadata command.
    • The returned document is the service’s edmx metadata + backend metadata

http://smpserver:8080/gateway/odata/sap/employee_MySQLDB;v=1/$metadata
