WINGS | WORKFLOW

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. The core ontologies are defined in OWL, while workflow templates, requests, and candidates are expressed in RDF. Many constraints are represented as RDF triples, others that are more complex are represented via Jena Rules... WINGS allows users to express high-level descriptions of their analysis goals, and assists them by automatically and systematically generating possible workflows that are consistent with that request. A high-level user request is one that only partially specifies what datasets, parameters, or software components are to be used. Users can be assisted in an interactive mode, where WINGS generates suggestions and validates their inputs, or in an automatic mode, where WINGS can elaborate their initial request and present the user with execution-ready workflows as options...
