WSDL Workshop. Semantic web application in HTML5 for the discovery, construction and analysis of workflows

Abstract

WSDL-Workshop is a HTML5 web application for the discovery and exploration of web services and for analysing the compatibility between web services. This is the result of a mathematical model developed from WSDL1.1. The program provides a graphical user interface and let the user build a workflow composed of services described with WSDL1.1 and tells if: ∙An output is compatible with an input. ∙It is correct to link an output with an input. ∙It is correct to link a given operation after another. ∙If many operations correctly linked together still make sense as a group. In order to do that the WSDLs must have semantic annotations so the computer can recognize what is the purpose of certain data or operation. WSDL-Workshop uses the EDAM Ontology as a reference for semantic concepts. In the discovery aspect; for a given set of WSDLs you can find services by filtering by operation name, input or output names, or semantic annotations. For a given operation output it can also filter by WSDL which have inputs which are correct to link with that output. For a given operation it can also filter by operations which are correct to link after.
