'''rCOS''' stands for refinement of [[Object (philosophy)|object]] and [[Software component|component]] systems. It is a [[formal method]] providing [[component-based]] [[model-driven software]] softwaredevelopment.

development. It was originally developed by [[He Jifeng]], [[Zhiming Liu]] and [[Xiaoshan Li]] at [[UNU-IIST]], and consists of a unified multi-view modeling notation with a theory of relational semantic and graph-based operational semantics, a refinement calculus and tool support for model construction, model [[analysis and verification]], and [[model transformations]]. Model transformations automate refinement rules and design patterns and generate conditions as proof obligations. rCOS support multiple dimensional modeling: models at different levels of abstraction related by refinement relations, hierarchy of compositions of components, and models of different views of the system ([[interaction protocol]]s of components, reactive behaviors of components, data functionality, and class structures and data types). For details, please visit http://rcos.iist.unu.edu/ for more details.
