    Giachetti, Giovanni; Alencar, Fernanda; Franch Gutiérrez, Javier; Pastor, Oscar (2010-01-31)
    External research report
    Open Access
    Nowadays, there exist modeling techniques that provide good support for the requirements elicitation and analysis of complex scenarios, such as the i* modeling framework. However, the application of these requirements ...
  • Definition and uses of the i* metamodel 

    Cares Gallardo, Carlos; Franch Gutiérrez, Javier; López Cuesta, Lidia; Marco Gómez, Jordi (CEUR-WS.org, 2010)
    Conference report
    Open Access
    The clear definition of a metamodel can be considered helpful for any conceptual modeling approach, and the i* framework is not an exception. Agreeing on a metamodel for i* can be considered even more convenient than ever ...
