The METADATA procedure sends an XML string to the SAS
Metadata Server. In SAS 9.3, depending on the value in the METHOD=
argument, DOREQUEST or STATUS, the IN= argument can contain a SAS
Open Metadata Interface method call that is formatted for the IOMI
DoRequest method. (This is legacy behavior.) Or, it can contain an
XML element that is supported in the IServer Status method.
The IOMI DoRequest method
is a messaging interface for SAS Open Metadata Interface methods.
It accepts all methods from the IOMI server interface, which consists
of methods for reading and writing metadata. It also accepts the IServer
Status method, which supports options for monitoring the server and
The ability to issue
Status requests outside of DoRequest is important because the DoRequest
interface is not available when the SAS Metadata Server is paused.
METHOD=STATUS enables you to use PROC METADATA to get SAS Metadata
Server status information while the SAS Metadata Server is paused.
