It is all in the data (Score 1)

I do not really care where the app sits, my computer, your computer, their computer on the ground or in the clouds but I really care about "my data". If the metadata belongs to the app provider they are a "joint owner" of my data - ouch. I am happy to pay license fees to whoever provides the app I am using at the time but I want to keep my data separate from the app. Portable data is the way to go after all it will be around a lot longer than the app - users need to require that the apps they use can export ISO 8000-110:2008 quality data.
