The goal-oriented paradigm is widely popular in Requirements
Engineering. However, the central notion of goal remains one of the
most controversial in the field. A possible cause might be that research
has devoted too little attention to studying the ontological foundations of
goal-oriented languages. In this paper, we have studied the case of GRL,
the goal-oriented requirements language being standardized by the ITU.
Our analysis followed the template-based approach proposed by Opdahl
and Henderson-Sellers. After defining a metamodel for GRL, we have
applied the template to each of its constructs to extract and formalize
detailed syntactic and semantic information. The semantic part of the
template focuses on establishing a mapping between a construct and its
meaning, defined in term of the Bunge-Wand-Weber ontology. Evaluations
of both GRL and the template are provided as well as suggestions
to improve them.
