title: Add a new data type to Pentaho Kettle
body: <p>I am trying to add a new data type (Geometry) to Kettle. I have added a new Value type to org.pentaho.di.compatibility. I have added a ValueGeometry class and made the necessary modifications to ValueInterface and Value. The code compiles but the new data type does not show up in plugins like Select. What am I missing here? Also I'd appreciate if you could point me towards the source code for these plugins.</p>
  
  <p>Thanks.</p>
