New in 5.3: Annotation operators

I just downloaded RapidMiner 5.3 and some shiny new things caught my eye. One thing I noticed was some new operators that allow annotations to be created within a process. Annotations are associated with IOobjects like data, cluster models, weights and you can store any free text you like with them. The annotation is retained with the IOobject if it is stored in the repository. With these new operators, it means you could add generated information such as a timestamp, the time taken to process the data or any other environmental information.

I have a lot of data lying around in my repositories and it would be very helpful if I had created a simple annotation to give me some clue what the data is and where it came from. Now I can.
