In this talk I give an overview of the design and application of
WebDSL, a domain-specific language for data centric web applications.
WebDSL linguistically integrates the definition of data models, user
interfaces, actions, access control rules, data validation rules,
styling rules, and workflow definitions.  While maintaining separation
between these concerns through specialized sub-languages, linguistic
integration ensures static consistency checking and correct code
generation.  The language allows developers to concentrate on the
essential design of web applications, abstracting from accidental
complexity, such as the details of data persistence.  The combination
of high-level and low-level constructs ensures high expressivity,
while supporting customization to application requirements.  The
application of WebDSL is illustrated using the researchr.org
application for bibliography sharing and reviewing.
