Metadata Authentication APIs
The vapi metadata authentication package provides services that expose authentication information for operation elements across all the service elements. To calculate the effective authentication information for an operation element, you should first see if there is an authentication scheme specified for the operation element. If it is not specified, then authentication scheme for the service element that contains this operation element is used. If it is not specified for the service element as well, then the authentication scheme for the package element that contains this service element is used.
The Component service provides operations to retrieve privilege information of a component element. A component element is said to contain privilege information if any one of package elements in it contains privilege information.
The Package service provides operations to retrieve privilege information of a package element. A package element is said to contain privilege information if there is a default privilege assigned to all service elements contained in the package element or if one of the operation elements contained in one of the service elements in this package element has privilege information.
The Service service provides operations to retrieve privilege information of a service element. A service element is said to contain privilege information if one of the operation elements contained in this service element has privilege information.
