Preliminary Experience Using JetBrains MPS to Implement a Requirements Specification Language

People prefer to use textual specification of requirements, but their representations are not suitable for automatic transformation and reuse. Use case modelling is commonly used to structure and document requirements. The integration of use cases within the Model Driven Development paradigm requires a rigorous definition of the use case specification. In this paper we describe the key part of SilabReq language for requirements specification based on use case and present the main result from our preliminary experience with implementation of the SilabReq language with JetBrains Meta Programming System.
