Towards a formal foundation of behavioral types for UML state-machines

Abstract

Behavioral types for model-based development comprise abstract behavioral aspects of the models they are associated with. Behavioral types allow checking that a model fulfills these behavioral aspects. Furthermore, as types can be related with each other, they support more complex checks and guarantees like compatibility in composition and refinement of models in a model based development process.We propose a behavioral type system and explain its properties, specifically targeting a subset of UML state-machines. We present an early implementation that generates behavioral type definitions out of an Eclipse-based modeling environment. These type definitions are generated for the higherorder proof assistant Coq as files. We present checking and comparison techniques based on these files for behavioral aspects that can be derived from the model definition.

On Behavioral Types for OSGi: From Theory to Implementation

“…

This report presents our work on behavioral types for OSGi component systems. It extends previously published work [8,9,10,11] and presents features and details that have not yet been published. In particular, we cover a discussion on behavioral types in general, and Eclipse based implementation work on behavioral types .

“…We present some core concepts on behavioral types to support a development process of component based systems. In our opinion (behavioral) types should provide a number of core concepts [11] to justify their classification as a type system:…”

Towards a Framework for Behavioral Specifications of OSGi Components

“…It realizes parts of our vision described in [6]. Unlike our work presented in [7], it is realized entirely using Java technology and is aimed towards the OSGi component system. A more comprehensive version of our OSGi semantics is described in a report [5].…”

Towards a Formalization of the OSGi Component Framework

“…Based on this, we presented formalisms for describing properties of OSGi systems. The semantics and the properties are intended to be used together with behavioral types [6,9] and related work [5] we are conducting.…”

“…We have advocated behavioral types in [9] and described a possible framework for OSGi and runtime verification in [6]. Interface automata [1] are one form of behavioral types that is similar to the one our component model is to be used with.…”
