Not all color can be represented digitally.

Is a piece of software subject to patents? Is it export controlled?

Both of those can change without the data changing at all. A new patent can be applied for and accepted, at which point all code the patent description matches is potentially encumbered (even if it was written with no knowledge of the patent or before the patent existed, yes our patent system sucks).

Export controlled is also a matter of laws, not an attribute of the data itself, and laws change independent of data.
