By now, all have been done to define data extraction rules. The user can preview them via pushing two buttons, MAP and GEM, in the right column of the work board.
After the button MAP has been pushed, the MAP instruction file is shown in the Mapping Editor tab window of the Output region. The left column of the window is an editor for the instruction file. It should be paid attention that the modifications in the editor could not be uploaded onto the DataStore server. The right column of the window has two buttons, i.e. TestThis and TestAll to test the instruction file. By pushing TestThis, the instruction file for this bucket is executed and the results are shown in the tab window Output. By pushing TestAll, all instruction files for this data schema are executed.
After the button GEM has been pushed, the GEM instruction file is shown in the GEM Editor tab window of the Output region. The left column of the window is an editor for the instruction file. It should be paid attention that the modifications in the editor could not be uploaded onto the DataStore server.
