An “abstract process” approach to algebraic dynamic architecture description

There is a natural intuition relating the concepts of algebraic process and architectural component; anyway, none of the existing approaches seems to have found the right balance between them. This article explains what is the problem with them, and defines the informal concept of abstract process, trying to provide a reference for the right level of abstraction. After presenting the concept, the article presents a dynamic, reflective Adl named PiLar, which has been designed using this notion. The syntax and semantics of this language are briefly summarized and explained. Finally, the classic example of the Gas Station is described in terms of PiLar, and then compared to previous presentations in other Adls.
