This looks like a really cool technical exercise showing how to apply IOTA, well done, and thanks for that.

I have one tiny comment though, on the direction of cashflow, from data owner to node owner. I wonder whether that is the right way round (Although it might be correct by convention- is the convention correct?). If we think about the data as being the valuable asset, it should maybe be the owner of the storage who pays to keep the asset, rather than the owner of the data, because the storage owner can generally charge for allowing access to the data, whereas the data owner cannot, so it seems fair for the storage owner to be paying revenue to the data owner.
