“…Therefore, in each context the object plays a different role. This introduces the notion of multiple perspectives [14]. The role is determined by the perspective the client holds on the object that plays the role.…”

“…Furthermore perspectives can change dynamically. This means that an object's set of methods may have additive and subtractive properties [14]. Thus, roles allow objects to evolve over time.…”

“…A class defines an entity, while a role only refines an entity in a certain context. Another argument is that with both concepts separated we can have separated inheritance hierarchies of classes and roles [14].…”

“…Thus roles must provide an interface, ensure encapsulation and have to be developed independently from other modules. It can be argued that modularization is a matter of design and not a language feature [14] and that we can have modularization in languages that do not provide encapsulation. While this is true, language design can enhance the use of modularization and favor good programming practices.…”

Although roles have been around for a long time they have not yet reached mainstream programming languages. The variety of existing role models may be a limiting factor. We believe that for roles to be widely accepted they must enhance code reuse. An outcome would be a library of roles. We present and discuss what we feel are the characteristics that a role model must have to enable reusable and playerindependent roles. In this paper we present our role model and JavaStage, a role language that extends Java, with examples of reusable roles. Finally, we present our steps towards the building of a role library, by presenting the roles developed from the analysis of the GoF Design Patterns. The results obtained, we developed roles for 10 of the 23 GoF patterns, are promising.

“…Roles are abstraction and decomposition mechanisms with notational systems in system analysis and design [19], [23], [24], [26], [29], [32], [34]. They are used as a tool to analyze the system requirements and ensure that future products reflect what a client hopes to receive.…”

Abstract-Software development tools are very important in software engineering. Although roles have been acknowledged and applied for many years in several areas related to software engineering, there is a lack of research on software development tools based on roles. Most significantly, there is no complete and consistent consideration of roles in all the phases of software development. Considering the increasing importance and applications of roles in software development, this paper intends to discuss the importance of roles in software engineering and that of role-based software development; review the literature relevant to role mechanisms in software engineering; propose and describe a role-based software process; and implement a prototype tool for developing complex software systems with the help of role mechanisms.
