Correctness of model-based software composition (CMC). Proceedings. ECOOP 2003 Workshop #11 in association with the 17th European Conference on Object-Oriented Programming, Darmstadt, Germany, July 22, 2003

This proceedings contains the contributions to the Workshop on Correctness of Model-based Software Composition, held in conjunction with the 17th European Conference on Object-Oriented Programming (ECOOP), Darmstadt, Germany on July 22, 2003. While most events concentrate on realisations of composition on the technological level this workshop aims at closing the gap of ensuring the intended composition result supported by the usage of models. Two important problems in composition are first how to model the different assets (such as components, features or aspects) and second the composition of assets such that consistency and correctness is guaranteed. The first problem has been addressed in the Workshop on Model-based Software Reuse (ECOOP 2002). The latter problem occurs when dealing with, e.g., component interoperability, aspect weaving, feature interaction and (on a more abstract level) traceability between different views or models. One approach to deal with the composition problem is to use models allowing to model the composition. This allows checking the interoperability of the different assets to compose, the correctness of the configuration of assets and predicting properties of the assembled system (especially compliance with user requirements). In case of problem detection suitable resolution algorithms can be applied. 10 reviewed contributions give an overview about current research directions in correctness of model-based software compositions. Results from the discussions during the workshop may be found in the ECOOP 2003 workshop reader to be published by Springer LNCS. The web page of the workshop as well as the contributions of this proceedings may be found at URL: http://ssel.vub.ac.be/workshops/ECOOP2003/ Affiliated to previous ECOOP conferences a related workshop about feature interaction (ECOOP 2001) and an additional about model-based software reuse (ECOOP 2002) have been held. Their contributions are published as technical report No. 2001-14 and as technical report No. 2002-4, respectively, at the Universitaet Karlsruhe, Fakultaet fuer Informatik.

Reflection on Turkish aspect-oriented software development workshop series

Cataloged from PDF version of article.In the last decade aspect-oriented software development (AOSD) has gained a broad interest in both academic institutions and industry. Likewise, several international conferences and workshops have been organized around the topic of AOSD. This paper summarizes the results of the national Turkish Aspect-Oriented Software Development Workshop series that have been organized in the last decade with the goal to stimulate the research and education on AOSD in Turkey. The fifth workshop was organized in December 2011. Aspects identified and demonstrated during the workshops have been collected in the so-called Aspect Browser. We report both on the experiences from the workshop series and the resulting aspect browser

Aspect-oriented interaction in multi-organisational web-based systems

Separation of concerns has been presented as a promising tool to tackle the design of complex systems in which cross-cutting properties that do not fit into the scope of a class must be satisfied. Unfortunately, current proposals assume that objects interact by means of object-oriented method calls, which implies that they embed interactions with others into their functional code. This makes them dependent on this interaction model, and makes it difficult to reuse them in a context in which another interaction model is more suited, e.g., tuple spaces, multiparty meetings, ports, and so forth. In this paper, we show that functionality can be described separately from the interaction model used, which helps enhance reusability of functional code and coordination patterns. Our proposal is innovative in that it is the first that achieves a clear separation between functionality and interaction in an aspect-oriented manner. In order to show that it is feasible, we adapted the multiparty interaction model to the context of multiorganisational web-based systems and developed a class framework to build business objects whose performance rates comparably to handmade implementations; the development time, however, decreases significantly.Comisión Interministerial de Ciencia y Tecnología TIC2000-1106-C02-0

Early aspects: aspect-oriented requirements engineering and architecture design

This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a presentation session and working sessions in which the particular topics on early aspects were discussed. The primary goal of the workshop was to focus on challenges to defining methodical software development processes for aspects from early on in the software life cycle and explore the potential of proposed methods and techniques to scale up to industrial applications

Pattern languages in HCI: A critical review

This article presents a critical review of patterns and pattern languages in human-computer interaction (HCI). In recent years, patterns and pattern languages have received considerable attention in HCI for their potential as a means for developing and communicating information and knowledge to support good design. This review examines the background to patterns and pattern languages in HCI, and seeks to locate pattern languages in relation to other approaches to interaction design. The review explores four key issues: What is a pattern? What is a pattern language? How are patterns and pattern languages used? and How are values reflected in the pattern-based approach to design? Following on from the review, a future research agenda is proposed for patterns and pattern languages in HCI

Modeling and Reasoning over Distributed Systems using Aspect-Oriented Graph Grammars

Aspect-orientation is a relatively new paradigm that introduces abstractions to modularize the implementation of system-wide policies. It is based on a composition operation, called aspect weaving, that implicitly modifies a base system by performing related changes within the system modules. Aspect-oriented graph grammars (AOGG) extend the classic graph grammar formalism by defining aspects as sets of rule-based modifications over a base graph grammar. Despite the advantages of aspect-oriented concepts regarding modularity, the implicit nature of the aspect weaving operation may also introduce issues when reasoning about the system behavior. Since in AOGGs aspect weaving is characterized by means of rule-based rewriting, we can overcome these problems by using known analysis techniques from the graph transformation literature to study aspect composition. In this paper, we present a case study of a distributed client-server system with global policies, modeled as an aspect-oriented graph grammar, and discuss how to use the AGG tool to identify potential conflicts in aspect weaving
