-  * CSV:filePath;col1Name,col2Name,... 
-  * TSV:filePath;col1Name,col2Name,... 
-  * URL:urlAddress;col1Name,col2Name,... (assume tab delimited)

-  - //dataset// folder in the model folder 
-  - //model// folder 
- 
-If the source contains more columns than needed, you may specify a list of columns as shown in the example above.
