Workflow Portal Download Page


WINGS (Workflow INstance Generation and Specialization) is a semantic workflow system that consists of the WINGS Portal, which is its user interface, and the WINGS Semantic Workflow Reasoner, which contains its constraint reasoning and propagation algorithms. The WINGS Portal can be used with the WINGS Semantic Workflow Reasoner or in a standalone manner. The function of the WINGS Semantic Workflow Portal is to interact with users to provide assistance in creating workflows. It runs on a Web browser, so that no code needs to be installed or downloaded to interact with the system. It allows users to: 1) upoload and describe datasets, 2) upload and describe workflow components, 3) create workflows, 4) set up and execute workflows, 5) examine execution results and their provenance. It has an open modular design and can be easily integrated with other existing workflow frameworks. It is built on open web standards from the World Wide Web Consortium (W3C) such as the Web Ontology Language (OWL), the Resource Description Framework (RDF), and the SPARQL query language for RDF. It can be used in conjunction with the Pegasus workflow mapping and execution system to provide scalable distributed workflow execution.
