  abstract = {In this paper we apply the role metaphor to coordination. Roles are used in sociology
as a way to structure organizations and to coordinate their behavior. In our
model, the features of roles are their dependence on an institution, and the powers
they assign to players of roles. The institution represents an environment where the
components interact with each other by using the powers attributed to them by the
roles they play, even when they do not know each other. The interaction between a
component playing a role and the role is performed via interfaces stating the requirements
to play a role, and which powers are attributed by roles. Roles encapsulate
their players' capabilities to interact with the institution and with the other roles,
thus achieving separation of concerns between computation and coordination. The
institution acts as a coordinator which manages the interactions among components
by acting on the roles they play, thus achieving a form of exogenous coordination.
As an example, we introduce the role construct in the Java programming language,
providing a precompiler for it. In order to better explain the proposal, we show
how to use the role construct as a coordination means by applying it to a dining
philosophers problem extended with dynamic reconffiguration.},
