UCEFlow: A syntax proposed to structuring the event flow of use cases

The Event Flow (EF) is the main part of the use case (UC) description. It is proposed structuring EF, through of grammar rules that guide and formalize their writing, using a syntax which is called UCEFlow (Structuring the Event Flows from Use Cases). This syntax enable the semiautomatic construction of sequence diagrams and obtain system prototypes through automatic transformations. building on the theory of Models Driven Development (MDD). It is planned to integrate the structured EF in CUPIDo template created at 2009 by the same research group. While this work is born with an educational purpose, is not out of reach to suggest that this structure, along with the CUPIDo template, will be used outside of academia, either in local companies or any other entity which is dedicated to software design, and help designers to document their UC in an orderly and efficient.
