The paper "WebWorkFlow: An Object-Oriented Workflow Modeling Language for Web Applications" by Zef Hemel, Ruben Verhaaf and Eelco Visser has been accepted for presentation at the conference on Model Driven Engineering Languages and Systems (MODELS 2008) to be held in Toulouse, France at the end of September 2008.
Workflow languages are designed for the high-level description
of processes and are typically not suitable for the generation
of complete applications.
In this paper, we present WebWorkFlow, an object-oriented
workflow modeling language for the high-level description of
workflows in web applications.
Workflow descriptions define procedures operating on domain objects. Procedures are composed using sequential and concurrent process combinators. WebWorkFlow is an embedded language, extending WebDSL, a domain-specific language for web application development, with workflow abstractions. The extension is implemented by means of model-to-model transformations. Rather than providing an exclusive workflow language, WebWorkFlow supports interaction with the underlying WebDSL language. WebWorkFlow supports most of the basic workflow control patterns.
