Seperating the two so cleanly is inappropriate imho. Software is the access layer around data, hence "Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious." -- Fred Brooks, The Mythical Man Month (1975) I would even say that software freedom implies or even requires data freedom, while the reverse does not hold. As an example I don't think that Facebook or Google's data export tools make them exemplars of user choice or control.
