“…The architecture consists of three reflective models: reflective object model, reflective scenario, reflective state. This reflective approach provides a self adaptable information system that extends the initial trial [4] to move reflection from linguistic to methodological.…”

“…This approach integrates reflection and design patterns, by reifying object model, scenario, and statechart of the system. This paper explores how to design a dynamically self-adapting system extending the idea of shifting reflection from linguistic to methodological, that has been presented by Cazzola et al in [4].…”

“…UML provides a special key, named stereotype, to deal with concepts not well-defined or difficult to model by using only class diagrams. Cazzola et al [4] adopt a special stereotype, named «causal-connection», to model with class diagrams a reflective system. This one has been the basic approach to reflective object-oriented analysis (ROOA).…”

Abstract. Today, complex information systems need a simple way for changing the object behavior according with changes that occur in its running environment. We present a reflective architecture which provides the ability to change object behavior at run-time by using design-time information. By integrating reflection with design patterns we get a flexible and easily adaptable architecture. A reflective approach that describes object model, scenarios and statecharts helps to dynamically adapt the software system to environmental changes. The object model, system scenario and many other design information are reified by special meta-objects, named evolutionary meta-objects. Evolutionary meta-objects deal with two types of run-time evolution. Structural evolution is carried out by causal connection between evolutionary meta-objects and its referents through changing the structure of these referents by adding or removing objects or relations. Behavioral evolution allows the system to dynamically adapt its behavior to environment changes by itself. Evolutionary meta-objects react to environment changes for adapting the information they have reified and steering the system evolution. They provide a natural liaison between design information and the system based on such information. This paper describes how this liaison can be built and how it can be used for adapting a running system to environment changes.

“…We leave for future work a declarative expression of pointcuts, e.g., based on OCL expressions. Cazzola et al proposed the reflective object oriented analysis [80] (ROOA) as a way to allow the non-functional properties of a model to be moved into a "meta-object" (i.e., objects describing properties of another objects). This approach can also be applied at the architectural level [81].…”

Open meta-modelling frameworks via meta-object protocols

Meta-modelling is central to Model-Driven Engineering. Many meta-modelling notations, approaches and tools have been proposed along the years, which widely vary regarding their supported modelling features. However, current approaches tend to be closed and rigid with respect to the supported concepts and semantics. Moreover, extending the environment with features beyond those natively supported requires highly technical knowledge. This situation hampers flexibility and interoperability of meta-modelling environments. In order to alleviate this situation, we propose open meta-modelling frameworks, which can be extended and configured via meta-object protocols (MOPs). Such environments offer extension points on events like element instantiation, model loading or property access, and enable selecting particular model elements over which the extensions are to be executed. We show how MOP-based mechanisms permit extending meta-modelling frameworks in a flexible way, and allow describing a wide range of meta-modelling concepts. As a proof of concept, we show and compare an implementation in the MetaDepth tool and an aspectbased implementation atop the Eclipse Modelling Framework (EMF). We have evaluated our approach by extending EMF and MetaDepth with modelling services not foreseen initially when they were created. The evaluation shows that MOP-based mechanisms permit extending meta-modelling frameworks in a flexible way, and are powerful enough to support the specification of a broad variety of meta-modelling features.
