• adapter
  The adapter element is the root element of the output map file.
• constant
  The constant element defines a data item with a constant value that is published to RMDS by the adapter.
• enum
  The enum element maps the value of the Event Stream Processor stream's service column to a unique string that is prepended to the name element of an update published to RMDS by the adapter.
• field
  In a stream definition in an output adapter map file, field specifies a column in a stream to publish.
• name
  In a stream definition in an output adapter map file, name specifies the column in the source stream that provides the value to use to identify each update.
• rfa
  The rfa element provides information for configuring the Reuters side of the adapter, including an explicit reference to the Reuters-side configuration file.
• service
  In a stream definition in an output adapter map file, service identifies a column in the source stream that is another component of the stream's unique key.
• stale
  In a stream definition in an output adapter map file, the stale element identifies a column in the source stream for which the value changes from 0 to 1 if the stream goes stale.
• stream
  In a subscription section in an output adapter map file, identifies the stream from which the adapter obtains the data it publishes to RMDS.
• subscription
  The subscription element contains one or more instances of the stream element, enabling you to configure the adapter to receive data from one or more streams.
