For message mappings like UADP, the Subscriber needs access to the DataSetMetaData to process received DataSetMessages. The Publisher can provide the DataSetMetaData through a dedicated queue.

The parameter MetaDataQueueName with the DataType String specifies the Broker queue that receives messages with DataSetMetaData sent by the Publisher for this DataSetWriter. This could be the name of a queue or topic defined in the Broker.
