Towards a Domain-Specific Language for the Renarration of Web Pages

We are interested in the problem of enabling transformation of existing, already published web pages. We call this Renarration of web content. In our earlier work, we had already established the role and importance of renarration for improving Web Accessibility. There are nearly a billion websites on the web, making transformation of pages a domain on its own. In this paper, we present the development of a Domain-Specific Language (DSL) for the purpose of web page transformation. We show how the design and implementation of our DSL is driven by our problem domain, its terminology and its unique requirements. We take up an existing online video-course delivery system, which has accessibility challenges, as a specific case to demonstrate our DSL. We end with insights and reflections for future work in both DSL and web page transformations.
