The first goal of the ReDSeeDS project is achieved. Requirements Specification Language (RSL) allows for defining requirements in precise way and is the basis for the ReDSeeDS Methodology. The first version of this new language is a result of collective work of consortium partners.
RSL integrates descriptions — constrained and unconstrained, conceptual modelling-based on object-oriented ideas and even user-interface specifications. RSL is, however, not simply an aggregation of existing concepts and language constructs. It has several distinguished and even unique features.
