+**RunOnTrigger** = : Absolute path of file that serves as trigger (has priority over StartDate/StopDate and overrides Runnable state). Trigger file will be deleted IFF ExitCode == 0 || ExitCode == 1 
+
+**StartDate** = Date Time to start the Task (YYY-MM-DDTmm:hh:ss)
+
+**StopDate** = Date Time to stop the Task (YYY-MM-DDTmm:hh:ss)

+
+**Command** = class| sh | perl | cmd: Command to be executed
+
+**FileType** | ProductType (1 - n) = : regular expresison for file type filtering. If not defined task will be executed without passing a file list 
+
+**LocalDestinationPath** = : Relative Path for directory to list File specified by a given <FileType> (relative to directory: $BASEPATH/$AOI/$PROCESSOR) 
+
+**MD5Filter** = true | false : Filters files defined in FileType/ProductType with check on exiting MD5 file. NOTE: for Downloads this can be set to 'false' whenever the server side file does not have an equivalent md5 file. For Distributions and Tasks it is advisable to have the default 'true' value in order to have a file completion validation, else the dataflow logic needs to guarantee file completion (default: true) 
+
+**LOCKFilter** = true | false : Filters files defined in FileType/ProductType with check on exiting LOCK file. This is used whenever a given Task should have exclusive access to a file, i.e. for parallelization. The LOCK file is deleted automatically whenever a Tasks returns form the execution of a given file

+**Parameter** (1 - n) = : Parameters to Command

+**<...>** (1 - n) = : Custom Tags that can be added and are passed as hastable (only available to Commands of type class
