It is too informal analogy and I am not sure that I understand Chinese philosphy (but I like it). The duality is one of the fundamental principles existing both in mathematics and physics. Its examples can be found everywhere. Here is only some examples;

references/offsets
point/line
data/code
entity/relation
rows/columns

So first we need to identify such dual things in programs, data and processes. Then the problem is how to formalize these observations and how to use them to build some new methods of data/program semantics representation and manipulation.
