Wings Portal

WINGS (Workflow INstance Generation and Specialization) is a semantic workflow system. The WINGS Portal is provided as a WAR file (Web Application ARchive) and runs in a Tomcat Server. It is backed by a Jena TDB Triple store as the Knowledge Base, and the PELLET Reasoner to do reasoning over it. We also use basic Jena Rules to do component-level reasoning.

The function of the WINGS 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) upload 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.
