Note
When describing a process, it could be confusing as a process relates some inputs to outputs. The information entity such as Issue could mean either a process of issuing or the issue result presenting as a page.
When describing a process in the macroscope, it is always a verb. The input/output is defined according to the function's specification.
Inputs - [Process] -> Outputs
There are 2 possible reasons why the input/output might be incomplete:
- Stateful functions which cause side effects or dependence on global variables: It is the trade-off when using functional representation. To stick to the functional representation style, we should think about how to reorganize the function so that it is closer to stateless.
- Not capturing the input/output that a function cares about: Ideally, every input/output should be captured at least in low precision (type system). But since there are complexity and obscurity when describing real-world knowledge, it is possible that the input/output is incomplete.
When describing the inner structure of a process, there are more kinds of modeling methods (we can see this in the complexity of programming). It is feasible to add more structure (corresponding to different semantics) but note that a compact structure (desired traits of knowledge representation) is preferable.
Loop primitive
In the simplest form, the process is the mapping of input to output. In addition, we add a Loop structure on top of it. See the LoopingConstructs Primitive in Mathematica Then, the diagram representing the function with loop will be:
