A Platform Dedicated to Share and Mutualize Environmental Applications

Scientists of the environmental domains (biology, geographical information, etc.) need to capitalize, distribute and validate their scientific experiments of varying complexities. A multi-function platform will be an adaptable candidate for replying this request. After a short introduction of our context and objective, this article presents the project MDWeb, a platform that we have conceived and realized for sharing and mutualizing geographic data. Based on this platform, our main interest is actually focused on providing users a workflow environment, which will be integrated soon after in this platform as a functional component. An introduction to a three-level workflow environment architecture (static, intermediate, dynamic) is presented. In this article, we focus mainly on the ”static” level, which concerns the first phase of constructing a business process chain, and a discussion around the ”intermediate” level, which covers both the instantiation of a business process chain and the validation, in terms of conformity, of the generated chain.
