A Goal based methodology for Web specific Requirements engineering

Web application domain requires specialized focus in Requirements Engineering because of their unique features like dynamic nature, presentation styles, large and heterogeneous audience, and navigational access to information. We propose WebURN notation, an extension to User Requirements Notation that is a goal and scenario based notation for early requirements analysis. An extended meta model for Goal Requirements Language and Use case Maps has been created for Web specific context. Also, the paper describes construction algorithms for creating the Requirements Analysis models from textual information entered by the Requirements Engineer. The Goal based approach, works closely with the Web specific functional and non-functional Requirements and delivers models with lesser conflicts, better choice amongst alternatives and handles crosscutting concerns corresponding to personalization and non-functional requirements.
