Roles’07 CALL FOR PAPERS

2nd Workshop on Roles and Relationships in Object Oriented Programming, Multiagent Systems, and Ontologies

Workshop co-located with ECOOP 2007 Berlin, July 30 and 31, 2007

Roles are a truly ubiquitous notion: like classes, objects, and relationships, they pervade the vocabulary of all sciences that deal with the nature of things and how these things relate to each other. In fact, it seems that roles are so fundamental a notion that they must be granted the status of an ontological primitive.

The definition of roles depends on the definition of relationships. With the advent of Object Technology, however, relationships have moved out of the focus of attention, giving way to the more restricted concept of attributes or, more technically, references to other objects. A reference is tied to the object holding it and as such is asymmetric—at most the target of the reference can be associated with a role. This is counter to the intuition that every role should have at least one counter-role, namely the one it interacts with. It seems that the natural role of roles in object-oriented designs can only be restored by installing relationships (collaborations, teams, etc.) as first-class programming concepts.

By contrast, the relational nature of roles is already acknowledged in the area of Multiagent Systems, since roles are related to the interaction among agents and to communication protocols. However, in this area there is no convergence on a single definition of roles yet, and different points of view, such as agent software engineering, specification languages, agent communication, or agent programming languages, make different use of roles. Like its predecessor “Roles, an interdisciplinary perspective” (Roles’05) held at the AAAI 2005 Fall Symposium (http://www.aaai.org/Press/Reports/Symposia/Fall/fs-05-08.php), this workshop aims at gathering researchers from different disciplines to foster interchange of knowledge and ideas concerning roles and relationships, and in particular to converge on ontologically founded proposals which can be applied to programming and agent languages. We invite all researches who have something to contribute to participate, by submitting an original paper of up to 8 pages and/or a position statement of max 2 pages (both Springer LNCS style). Every submission should either propose a new definition of ‘role’ or make a clear statement regarding the definition of ‘role’ used. The first day of the workshop will be devoted to presentations, the second one to discussions leading to a “Role Manifesto”. Ideally, if not an authoritative definition of the role concept, at least a provisional one eliciting the features common to most approaches should emerge from this workshop; the process will be continued after the workshop using a cooperative website.

Research and mature ideas that focus on the following topics are particularly welcome: · Roles as first-class constructs in programming, modelling, ontologies, and multiagent systems · Relationships as first-class programming constructs · Applications that would profit from roles and relationships · Patterns dealing with the realization of relationships and roles · Roles in foundational ontologies and applicative ontologies · Roles in models (e.g. UML) and domain-specific languages · Roles in multiagent systems design, specification and programming · Experience reports with role-oriented approaches · Existing and new programming constructs related to roles · Literature surveys on roles · Reports on roles from other disciplines, like sociology, organizational theory, linguistics, etc.

Submissions should be uploaded at http://roles07.di.unito.it/. For more information about formatting the paper please consult the Springer LNCS web site at http://www.springer.de/comp/lncs/authors.html

Questions should be sent to Guido Boella (guido [at] di.unito.it).

The papers will be reviewed by at least 2 members of the program committee composed of experts in the different areas covered by the workshop.

Papers will be published in the workshop proceedings. As in the previous edition of this workshop, high quality of submission provided, there may be a special issue of some renowned journal containing extended versions of the best workshop papers.

Important Dates • May 15, 2007: Submissions due • May 31, 2007: Notifications of acceptance • June 15, 2007: ECOOP Early registration deadline • July 30-31, 2007: Workshop at ECOOP
