Abstract:
Most web applications are
data-intensive, i.e. they heavily rely on dynamic contents
usually stored in databases. Website design and
maintenance can greatly benefit from conceptual
descriptions of both data and hypermedia aspects, i.e.
those design dimensions which distinguish this application
class: the data upon which the content is based, the way
dynamic contents are composed together to form pages, and
how pages are linked together in order to move across the
application content. The paper proposes Webile, a
visual Domain-Specific Language based on UML, which
enables a model-driven approach to high-level
specification of web applications. In contrast with other
approaches, Webile exploits the UML meta-model
architecture by serialising the specifications in the XMI
interchange format. This representation provides
interoperability amongst different operative platforms and
enables a XSL transformation-based automatic generation of
the applications being designed. |
