Tutorial Processes
Extracting the Source annotation from an example set
The process loads the Iris data set. The Retrieve operator automatically creates the Source annotation which specifies from where the data has been loaded.
The Extract Macro from Annotation operator then extracts the value of that annotation into a macro, which is printed to the console in the next step. Have a look at the process log after executing the process!
To see the annotations of an object go to the results view and select the Annotations display option.
