Towards separation of concerns in flow-based programming

Abstract

Flow-Based Programming (FBP) is a programming paradigm that models software systems as a directed graph of predefined processes which run asynchronously and exchange data through input and output ports. FBP decomposes software systems into a network of processes. However there are concerns in software systems which do not fit this dominant decomposition. In this paper, we address the cross-cutting-concerns in FBP by using some examples and propose an aspect-oriented extension to FBP.
