A Grammar for ADVANCED SBVR Editor

Semantics of Business Vocabulary and Business Rules (SBVR) is the richest knowledge model allowing to create specifications that are understandable for business people and also interpretable by computers. Existing SBVR editors still lack capabilities that could allow generating formal SBVR models, adapting SBVR to several languages or making SBVR extensions for various purposes (e.g., implementing transformations to software modelling languages) without changing the original SBVR metamodel. The goal of the paper is to present a grammar for SBVR structured language and a prototype of SBVR editor, created on the base of this grammar. An experiment conducted with the prototype has shown that it allows defining business vocabularies, business rules and questions in SBVR structured English and Lithuanian languages; producing formal SBVR models; using concepts from several vocabularies, and extending SBVR without changing its metamodel.
