GORO 2.0: Evolving an Ontology for Goal-Oriented Requirements Engineering

Goal-Oriented Requirements Engineering (GORE) gained prominence by covering some of the limitations of traditional Requirements Engineering (RE). As a result, many GORE modeling languages have been proposed since this field emerged. Aiming at providing formal semantics to the concepts of GORE, the Goal-Oriented Requirements Ontology (GORO) was proposed as a common vocabulary for this domain. However, the first version of GORO lacks important concepts and its applicability was not demonstrated in practice. In this paper, we present GORO 2.0, an evolution of the first version of GORO that overcomes several limitations of its first version, presenting new concepts such as obstacles, conflicts and contributions.
