Abstract

Many extensions have been proposed since the initial iStar version, in the 90's. We have been analysing these extensions and proposing ways to support new ones. In previous work, we have proposed extension mechanisms to iStar 2.0. Since modelling tools play a central role during the modelling of systems, we believe that a modelling tool that supports the creation of extensions through a graphical user interface could make this task easier. In this paper, we report on the results of supporting iStar extensions with piStar-ext, an iStar 2.0 web modelling tool. Our tool allows the proposal of new constructs using textual representation as well as new symbols. We illustrated our proposal by representing an existing iStar extension with the new features included in piStar-ext.
