GetResponse (Metadata Exchange) Message

A GetResponse message is a WS-Transfer message used to respond to a request for metadata. For more information about GetResponse messages, see section 3.1 of the WS-Transfer Specification.

Any DPWS application that sends Get messages will receive GetResponse messages.

Note

This topic shows a sample DPWS message generated by WSDAPI clients and hosts. WSDAPI will parse and accept other DPWS-compliant messages that do not conform to this sample. Do not use this sample to verify DPWS interoperability; use the WSDAPI Basic Interoperability Tool (WSDBIT) instead.

 

The following SOAP message shows a sample GetResponse message.
