In this paper we present a new vision of objects in knowledge representation where the objects’ attributes and operations depend on who is interacting with them. This vision is based on a new definition of the notion of role, which is inspired by the concept of affordance as developed in cognitive science. The current vision of objects considers attributes and operations as being objective and independent from the interaction. In contrast, in our model interaction with an object always passes through a role played by another object manipulating it. The advantage is that roles allow to define operations whose behavior changes depending on the role and the requirements it imposes, and to define session aware interaction, where the role maintains the state of the interaction with an object. Finally, we provide a description of the model in UML and we discuss how roles as affordances have been introduced in Java.

Abstract

In this paper we present a new vision of objects in knowledge representation where the objects’ attributes and operations depend on who is interacting with them. This vision is based on a new definition of the notion of role, which is inspired by the concept of affordance as developed in cognitive science. The current vision of objects considers attributes and operations as being objective and independent from the interaction. In contrast, in our model interaction with an object always passes through a role played by another object manipulating it. The advantage is that roles allow to define operations whose behavior changes depending on the role and the requirements it imposes, and to define session aware interaction, where the role maintains the state of the interaction with an object. Finally, we provide a description of the model in UML and we discuss how roles as affordances have been introduced in Java.
