Customizable software requirements languages
Akira Ohnishi A · 2002
The author presents a software requirements specification method with a visual language (VRDL) and a text base language (X-JRDL). VRDL language allows to define both the shape and semantics of any icons to specify requirements just what he imagines. X-JRDL language based on the case grammar allows to define case structures of any new verbs to specify requirements naturally and easily. In this sense these languages are customizable. Since these two languages are based on the same model, their internal representations have the same scheme. This fact means that a describer can write down requirements with either/both VRDL or/and (X-JRDL). The model which gives the basis of the languages, features of the languages, and some examples are described.>
