The workflow of InterformNG2 is able to handle many different file types. The file type is also referenced as the payload of the workflow.

Another way to express it like so:

When you call a workflow, then most workflow input types expects, that the workflow is called with a file as a parameter (or payload).

Each component in the workflow also expects a specific input file type (or payload) as input and each component also outputs a file type/payload, which may be different from the input file type.
