• adapter
  The adapter element is the root element of the map file.
• dataField
  In the streamMap definition, the dataField element maps one column from a source stream to a Reuters Field ID (FID).
• dateTimeField
  In the streamMap definition, the dateTimeField element maps a Reuters date or time FID (or one of each) to a date column, a timestamp column, or both, in a stream.
• FIDListField
  In the streamMap definition, the FIDListField element maps all of the Reuters FIDs with their values for an event to the Event Stream Processor source stream.
• item
  The item element is used to identify a RIC to which the Reuters Marketfeed adapter subscribes.
• itemList
  The itemList element contains one or more instances of the item element.
• itemLists
  The itemLists element contains one or more instances of the itemList element.
• itemName
  In the streamMap definition, the itemName element identifies the row in the Event Stream Processor source stream that carries the RIC from the RMDS update.
• itemStale
  In the streamMap definition, the itemStale element identifies a column in the Event Stream Processor source stream that carries a flag indicating whether incoming RMDS data has gone stale.
• nullField
  In a streamMap, the nullField element acts as a placeholder that always delivers a NULL value to the stream. This lets you add extra fields to a source stream to get the configuration you want.
• publication
  The publication element specifies basic operating parameters for this instance of the adapter.
• recordType
  The recordType element maps a stream to a predefined set of FIDs.
• recordTypeMap
  The recordTypeMap element contains one or more instances of recordType.
• rfa
  The rfa element links the input adapter map file to the Reuters-side configuration file.
• sequenceNumber
  In the streamMap definition, the sequenceNumber element maps a column in the source stream that is populated by a unique number generated by the adapter, not provided as part of the data from RMDS.
• serviceName
  In the streamMap definition, the serviceName element maps a column in the source stream to the service identifier that the adapter provides as part of the envelope for each update.
• streamMap
  The streamMap element contains the mappings between the columns of an Event Stream Processor source stream and the RMDS FIDs being subscribed to by the adapter.
• streamMaps
  The streamMaps element contains one or more instances of the streamMap element.
• updateNumber
  In the streamMap definition, the updateNumber element maps a column in the Event Stream Processor source stream that is populated by a unique number generated by the adapter, not provided as part of the data from RMDS.
