Abstract

Workflows have an increasing role in scientific applications programming and business environment development because they are an effective technology to define composition of different pieces of knowledge, both in the application domain and in the business context. However, workflows are addressed in a number of different perspectives and no consensus has been reached yet on the language, modelling, and systems, to adopt in advanced contexts like Grid or semantic Web. In this paper, we describe a graphical tool for supporting different kinds of users in authoring workflows running on next generation Grids. The tool, named Semantic Workflow Programming Tool, is based on a reference workflow model that has been developed to provide advanced functionality with respect to the currently available workflow description. Design and functionality of the tool resulted from requirements and scenarios emerged in the EU funded NextGRID project, in whose context the tool is developed.
