International Workshop on Early Aspects


10th Int. Conf. on Aspect-Oriented Software Development (AOSD 2011)

Porto de Galinhas (Pernambuco, Brazil) March 21st, 2011

Workshop on Aspect-Oriented Requirements Engineering and Architecture Design

"Giving Birth to Modular Software"

Aspects aim to encapsulate properly well-defined concerns which are difficult or simply not feasible to modularize using traditional techniques (e.g., object-oriented). Early aspects aim to identify and modularize these concerns during the requirements analysis, domain analysis and architecture design, in order to avoid non modular and potentially tangled and scattered implementations. Work on early aspects focuses on systematically identifying, modularizing, and analyzing such concerns and their impact at these early phases of the software development.

The present edition of the workshop provides a forum for an open set of early-aspects related topics, without restricting to a specific theme or domain.

According to this year AOSD conference topic, we would like to open the workshop to other software paradigms related to Early Aspects, such as feature-oriented software development, whose goal is also to create software as modular as possible.


The general aim of this workshop is to facilitate cross-fertilization of ideas in requirements engineering, domain engineering, software architecture design and aspect-oriented software development in order to identify new challenges, discuss on-going work and potential solutions, analysing different alternatives and identifying strengths and weaknesses of each alternative. This should contribute to the maturation of Early Aspects as a discipline. The present edition of the workshop will provide a forum for an open set of early-aspects related topics, without restricting to a specific theme or domain.

This year we would like to invite people from other related communities, such as feature-oriented requirements engineering or architecture-design, and model-driven development, to contribute to the Early Aspects workshop. The goal, aligned with this year AOSD conference topic, is to create a venue where people researching about modular software at the early stages of the software development lifecycle can expose and discuss novel and potential ideas. This should help to identify synergies between closely-related communities and potentially adopt solutions to common problems.

Workshop Format

The workshop will be highly interactive with a few presentations in the morning followed by group work for the rest of the day. The participants will work in small groups, formed based on their specific interests. The group work will be focused on making a tangible progress by identifying possible solutions of the discussion problems; by furthering the problem understanding; by providing practical examples and motivation for the discussion topics, etc. The last session of the workshop will be dedicated to integrating the results of the group discussions into the overall workshop results.

Invited Talk: CRADLE - Concern Relationships At Different LEvels of abstraction
Gunter Mussbacher (Carleton University)

Abstract: Separation of concerns and information hiding have long been regarded as fundamental cornerstone techniques to address complex technical problems of software engineering. Modern software development advocates separation of concerns and information hiding in all development phases. The organization of software into modules directly follows from these two key principles. While the refinement of concerns (i.e., modules) has received great attention in the software engineering community, the refinement of relationships between concerns has received much less attention. In recent years, aspect-oriented techniques have allowed to further formalize relationships between concerns. Initial results for an end-to-end aspect-oriented software development process have emerged, but the focus is still not as much on concern relationships as it arguably should be. This talk explores concern relationships and poses several research questions in this area.

Speaker Short Bio: Gunter Mussbacher received a M.Sc. degree in computer science from Simon Fraser University in 1999, and a Ph.D. in computer science from the University of Ottawa in 2010. In his thesis, he developed the Aspect-oriented User Requirements Notation (AoURN), a framework that enables goal-oriented, scenario-based, and aspect-oriented modeling in a unified way. After his M.Sc., he worked as a research engineer for the Strategic Technology department of Mitel Networks, where he applied and taught URN concepts. He has published in the Requirements Engineering Journal (REJ) and in the Transactions on Aspect-Oriented Software Development (TAOSD), and co-edited with Daniel Amyot the URN standard (ITU Recommendation Z.151 11/2008). He is also teaching software engineering undergraduate courses as well as URN and AoURN tutorials for industry and at international conferences. His general research interests lie in requirements engineering, URN, aspect-oriented modeling, and patterns. Gunter is an organizer or program committee member of Early Aspects (EA), Aspect-oriented Modeling (AOM), Systems Analysis and Modelling (SAM), and Model-Driven Requirements Engineering (MoDRE) workshops as well as the System and Design Languages (SDL) conference since 2008.
