The i* framework is a popular conceptual modeling language for capturing the social characteristics of complex systems in terms of actors, their intentions, and their relationships. In November 2008, the International Tele- communications Union standardized the Goal-oriented Requirement Language (GRL) as part of the User Requirements Notation (URN). GRL is based on an extended subset of i*, and both share many concepts. However, GRL is rather permissive and can be used in ways that deviate from conventional i* modeling guidelines. In addition, some i* concepts do not have equivalent first-class con- cepts in GRL. In this paper, we present a lightweight GRL profile for i* that takes advantage of GRL’s extensibility features to capture missing i* concepts. We also present formal constraints on the use of GRL and its extensions to re- strict it to an i* style. This profile enables GRL modeling and analysis tools to be used for i* models, resulting in i* models that conform to an international standard and that can be integrated with URN’s scenario notation, namely Use Case Maps. This profile is implemented in the jUCMNav modeling tool.
