Example defining the details of a Process

[rokroskar]

The wfdesc spec for http://purl.org/wf4ever/wfdesc#Process states that

It is out of scope for wfdesc to classify or specify the nature of the process, this should be done by subclassing and additional subproperties

Is there an example of how this is envisioned to look? I'm surprised there are only input and output properties defined but nothing about the process itself. Which ontologies should be used to further specify Process? For example, I would like to express the command that was run and its arguments.
