Conceptual modelling of Web applications, workflows and Web services

Conceptual modelling has recently gained attention as a means for formalizing the development process of Web applications, opening the way to the benefits of software engineering also in the Web context. New applications demand the extension of hypertextual front-ends with workflow functionality and with the ability of interacting with remote Web services. This scenario poses new challenges to Web conceptual models, which must be able to capture new requirements.
