iStarJSON: A Lightweight Data-Format for i* Models iStarJSON has been carried out in the context of a general framework for Open Source Software ECOsystems (OSSECOs) quality analysis and modelling process. i* is used to represent OSSECOs, and the framework uses model analysis for OSSECO quality analysis (e.g., identifying main goals, members relationships, strategic dependencies)

An iStar model is a directed graph

Atype = {association;dependency;means_end;decomposition;contribution}

Dependencies are represented by three nodes (depender, dependee and dependum) and two links, one from the depender to the dependum and other from the dependum to the dependee.
