• adapter
  The adapter element is the root element of the map file.
• dataField
  In the streamMap definition, the dataField element maps a Reuters Field ID (FID) to one column in a source stream.
• dateTimeField
  In a streamMap, the dateTimeField element maps a Reuters date or time FID (or one of each) to a date column, a timestamp column, or both, in an Event Stream Processor source stream.
• hiResTimestampField
  The hiResTimestampField element substitutes a high-resolution timestamp for the regular timestamp.
• imageField
  The imageField element indicates whether or not the Event Stream Processor row is part of a snapshot initial image.
• item
  The item element identifies an RIC to which the Reuters OMM 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 an indicator of whether or not incoming RMDS data has gone stale.
• marketByOrderKeyField
  The marketByOrderKeyField element is a secondary key for messages of the MARKET_BY_ORDER domain.
• marketByPriceKeyField
  The marketByPriceKeyField element is a secondary key for messages of the MARKET_BY_PRICE domain.
• marketMakerKeyField
  The marketMakerKeyField element is a secondary key for messages of the MARKET_MAKER domain.
• nullField
  In a streamMap, the nullField element acts as a placeholder that always delivers a NULL value to the Event Stream Processor source stream. This lets you add extra fields to a source stream to get the configuration you want.
• publication
  The publication element specifies basic publishing information for this instance of the adapter.
• respTypeNumField
  The respTypeNumField element populates a column with the RMDS respTypeNum value.
• rfa
  The rfa element links the subscriber map file to the Reuters-side configuration file.
• sequenceNumber
  In the streamMap definition, the sequenceNumber element maps a column in 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.
• serviceName
  In the streamMap definition, the serviceName element maps a column in the Event Stream Processor source stream to the service identifier that the adapter provides.
• streamMap
  The streamMap element of the input map file defines 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 of the input map file contains one or more streamMap elements.
• updateNumber
  In the streamMap definition, the updateNumber element maps a column in Event Stream Processor source stream that are populated by a unique number generated by the adapter, not provided as part of the data from RMDS.
