Abstract. The User Requirements Notation (URN) combines the Goaloriented Requirement Language (GRL) with the Use Case Map (UCM) scenario notation. Although tools exist in isolation for both views, they are currently not meant to work together, hence preventing one to exploit URN to its fullest extent. This paper presents jUCMNav, a new Eclipse-based tool that supports both UCM and GRL in an integrated way. jUCMNav supports links between the two languages that can be exploited during analysis. An overview of the current editing and analysis capabilities is given, with a particular emphasis on the new concept of GRL strategies, which simplify the evaluation of GRL models. The extensibility of the tool is also discussed.

Abstract

The Use Case Map (UCM) notation enables the use of graphical scenarios to model grey-box views of a system's operational requirements and behaviour, in context. The scenario traversal mechanism is the most popular UCM analysis technique but its current tool support in UCMNav is limited and hard to use, and the high coupling of its features makes it difficult to maintain and evolve. This paper presents major enhancements to the recent jUCMNav Eclipse plugin consisting of a new scenario traversal semantics accompanied by enhanced trace transformations to Message Sequence Charts. In addition, this paper identifies a set of semantic variation points which lay the groundwork for notational clarifications and user-defined semantic profiles.
