Foil 31 Wrapping Existing Applications

From Full Description of WebFlow and Friends for Education and Science Portals NCSA Portal/Metadata Meeting -- October 22-23 99. by Geoffrey C. Fox, Tom Haupt


Currently each application is wrapped "by hand"
Users would like to automate the process -- "especially for simple jobs" -- need a Object Wrapping Wizard
Current XML Task Specification is at level of files
Will extend XML to include parameters so can automate construction of
  • Web Interfaces to input parameters with defaults etc. and create XML input file for job
  • Library for allow jobs to access parameters
