Collapse Button Quick Abstract
By designing systems as sets of modules that can be composed into larger applications, developers unleash a multitude of advantages. The promise of AOP (Aspect-Oriented Programming) is to enable developers to organize crosscutting concerns into separate units of modularity making it easier to accomplish this vision. However, AOP does not allow unit tests to be untangled, which impairs the development of properly tested independent modules. This paper presents a technique that enables developers to encapsulate crosscutting concerns using AOP and still be able to develop reusable unit tests. Our approach uses incremental testing and invasive aspects to modify and adapt tests. The approach was evaluated in a medium scale project with promising results. Without using the proposed technique, due to the presence of invasive aspects, some unit tests would have to be discarded or modified to accommodate the changes made by them. This would have a profound impact on the overall modularity and, in particular, on the reusability of those modules. We will show that this technique enables proper unit tests that can be reused even when coupled with aspect-oriented code.

Collapse Button Quick Abstract
In cloud computing, lock-in refers to the difficulty of porting an application from one platform to another. An example of such difficulty can be witnessed when porting an application from Platform-as-a-Service Google App Engine to Microsoft Azure. Differences in their implementations are substantial, yielding non-portable applications. Standardization could address this problem, but existing initiatives are still to be accepted. This paper addresses lock-in by proposing a model-driven engineering design approach that decouples platform specific code from the application logic. The resulting platform-independent models, as well as corresponding model transformations, can be reused to generate distinct platform-specific implementations, hence reducing the programming effort spent coding repetitive tasks. Such transformations can be made available for reuse on a repository for cloud providers. We have implemented transformations to handle persistence for Google App Engine and Azure, and discuss how model-driven engineering can reconcile the differences between features of the persistence models of GAE and Azure.

Collapse Button Quick Abstract
The i* framework proposes a goal-oriented analysis method for requirements engineering. It is a systematic approach to discover and structure requirements at organizational level where functional, non-functional requirements and their relations are specified. A Domain Specific Language (DSL) has the purpose to specify and model concepts in some domain, having several advantages in relation to general purpose languages, such as it allows expressing a solution in the desired language and at the desired abstraction level. In order to create such a DSL, normally it is necessary to start by specifying its syntax by means of a metamodel to be given as input to the language workbenches that generate the corresponding editors for it. With a proper editor for the language we can specify models with the proposed notation. This paper presents a DSL for the i* framework, with the purpose to handle complexity and scalability of its concrete models by introducing some innovations in the i* framework metamodel like mechanisms that will help to manage the models scalability.

Collapse Button Quick Abstract
Web-GIS applications evolve fast as new requirements emerge constantly. Some of these requirements, particularly those related with spatial behaviours, might crosscut previous core application requirements. Conventional modelling techniques, which ignore the effect of crosscutting concerns (such as tangling and scattered behaviours) affect negatively the modularity and thus compromise application maintenance. In this paper we present and aspect-oriented approach to model crosscutting concerns in Web-GIS applications, particularly those related with spatial features. The process introduced in this paper starts with the identification and specification of crosscutting concerns, followed by the composition of these concerns, using the MATA language.

VAODA - A Viewpoint and Aspect-Oriented Domain Analysis Approach

Collapse Button Quick Abstract
Requirements approaches can be integrated to specify domain requirements. Among them, viewpoint-oriented approaches stand out by their simplicity, and efficiency in organizing requirements. However, none of them deals with modularization of crosscutting concerns. Aspect-Oriented Domain Analysis (AODA) is a growing area of interest as it addresses the problem of specifying crosscutting properties at domain analysis level. The goal is to obtain a better reuse at this abstraction level through the advantages of aspect orientation. This work proposes an AODA approach that integrates feature modeling and viewpoints.

Collapse Button Quick Abstract
This paper presents a metadata-driven approach based on aspect-oriented requirements analysis. This approach has been defined in cooperation with the European Space Agency in the context of the “Aspect Specification for the Space Domain” (ASSD) project. ASSD aims at assessing the applicability and usefulness of aspect-orientation for the space domain (ground segment software projects in particular), focusing on the early stages of the software development life cycle. This paper describes a rigorous representation of requirements analysis concepts, refines a method for handling early aspects, and proposes a client/server architecture based on a metadata repository.

Collapse Button Quick Abstract
This paper describes how to rank refactoring patterns to improve a set of quality attributes of a piece of software. The Analytical Hierarchy Process (AHP) is used to express the relative importance of the quality attributes and the relative importance of refactoring patterns in regards to those selected quality attributes. This ranking of refactoring patterns can be used to focus the refactoring effort on the most beneficial patterns to the software being developed or maintained.

Collapse Button Quick Abstract
This paper presents an aspect metadata approach, which has been developed in the scope of the “Aspect Specification for the Space Domain” project. This approach is based on XML and XML Schema technologies, enabling a rigorous knowledge representation. The proposed approach has been applied to a real complex system, the “Space Environment Support System”, enabling a comparison and evaluation between the proposed approach and the “traditional” requirements analysis methods used during the development of the original version of the system. This paper presents a full description of both the identified metadata concepts and their relationships. The metadata concepts and associated instances have been stored in a Metadata Repository that provides simple navigation facilities between concepts. The Metadata Repository also enables the automatic generation of documentation.

Collapse Button Quick Abstract
Analysis Patterns are indicative analysis solutions for a recurrent problem. Many patterns have been proposed and are successfully used. The writing of a pattern follows a specific structure that can be tailored to each author’s needs. We have developed an analysis pattern template that solves some previously identified gaps on other approaches. This paper focuses on the definition of a systematic process to guide developers to fill in that analysis pattern template. This process will contribute to the unification of the analysis patterns representation, and thus for their understandability and completeness.

Collapse Button Quick Abstract
Separation of concerns refers to the ability of identifying, encapsulating and manipulating parts of software that are crucial to a particular purpose (Dijkstra, 1976). Traditional software development methods were developed with this principle in mind. However, certain broadly-scoped properties are difficult to modularize and keep separated during the lifecycle, producing tangled representations that are difficult to understand and to evolve. Aspect-oriented software development aims at addressing those crosscutting concerns, known as aspects, by providing means for their systematic identification, separation, representation and composition. This paper focuses on the representation and composition activities, by proposing an XML-based language to specify and compose concerns at the requirements level. An illustration of the proposed approach to an example supported by a tool is presented.
