This portal provides access to the Wings semantic workflow system by allowing you to browse, set up, and run workflows. Some unique features of Wings that can assist a user include:
You can walk through some Wings Tutorials and Videos that guide you through the basics of creating and using workflows.
Workflow systems can automate many aspects of workflow creation and execution. The WINGS workflow system developed at USC/ISI illustrates these capabilities, with WINGS providing user assistance and automatic workflow validation and generation. The WINGS portal is setup by default to run locally, but it can use different execution engines such as OODT and Pegasus
WINGS (Workflow INstance Generation and Specialization) uses AI planning and semantic reasoners to assist users in creating workflows while validating that the workflows comply with the requirements of the software components and datasets. WINGS can reason about the constraints of the components and the characteristics of the data and propagate them through the workflow structure. WINGS reasons over semantic workflow representations that consist of both a traditional dataflow graph as well as a network of constraints on the data and components of the workflow.
Wings workflow repositories are available through other portal sites installed for use of specific research groups. These collections include workflows for population genomics, for educational student assessment, and for social network analysis. Each of these sites contains datasets and the executable codes for all workflow steps in their collection, so the workflows can submitted for execution at the location where that particular Wings portal installation is set up.
The WINGS workflow system has an open modular design and can be easily integrated with other existing workflow systems and execution frameworks to extend them with semantic reasoning capabilities. We have integrated the Wings semantic workflow system with other user interfaces, and submitted workflows with a variety of execution engines. WINGS 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.
If you are interested in using the Wings semantic workflow reasoners with your own workflow framework, or in setting up your own installation of a Wings workflow portal, please contact us.
Publications providing overviews and technical descriptions of how Wings works are available in the Wings web site.
