[[Goal-oriented Requirements Language]] (GRL) is a language that is designed to support [[goal-oriented]] modeling and reasoning about requirements, especially the non-functional requirements <ref>Lin Liu, Eric Yu, “Designing information systems in social context: a goal and scenario modelling approach”</ref> It allows to express conflict between goals and helps to make decisions that resolve conflicts. There are three main categories of concepts in GRL: intentional elements, intentional relationships and actors <ref>GRL web site, University of Toronto, http://www.cs.toronto.edu/km/GRL/</ref>. They are called for intentional because they are used in models that primarily concerned with answering "why" question of requirements (for ex. why certain choices for behavior or structure were made, what alternatives exist and what is the reason for choosing of certain alternative.
