  1. ToolKit for Large-SCAle studies of Web documents SI4 June Project Imane BELLAT – Bastien BLANCHARD Clément TOCHE – Maurice YARED

  2. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • Web documents evaluation process • Co-operating services • Evaluations and Requirements • Web Accessibility Initiative (WAI) • Checkpoints from the Web Content Accessibility Guidelines • Additional Services • Page Rank • W3C Validation • PrettyPrint of statistics Accessibility : multiple paradigms

  3. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • Grid Workflow Efficient Enactment for Data Intensive Applications (Gwendia) • Workflow description framework • Grid Infrastructure • Optimizingdistributed computation • MOTEUR as WorkFlow Manager • Goal • Accessibility tests on elements in HTML, CSS, Script code Scalability Tools

  4. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • Project Subject • Initial WorkFlow • Vision of Architecture • Code Implementation • WorkFlow Structure • WorkFlow WithModularity • Concept • WorkFlow Structure • More Complex WorkFlow • Vision of Architecture • WorkFlow Structure • Some Tests • Problems • Outlooks Agenda

  5. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests Vision of Architecture

  6. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests Code Implementation • Subdivision of WorkFlow in Processors • Encoding processors • BeanShell • Internal MOTEUR Java Code • Directlydeployed on the grid • Common WebServices • Accessible through Web Service Description Language (WSDL)

  7. WorkFlow Structure Data Entrance Loading Data RetrievingElements Processing data Processing results

  8. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • Meeting the needs of developers wishing to expand treatments • Communication constraints • Modularity : • By Layers • By Processors Concept of Modularity Contract Models Implementation

  9. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests Data flow Data contract

  10. WorkFlow Structure Data Entrance Loading data Retrieve elts Retrieve elts 2 Processing data Processing results

  11. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests Vision of Architecture

  12. WorkFlow Structure Data Entrance Domain Loader Loading data Retrieve elts Retrieve elts 2 Processing results Processing data

  13. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests Pretty Printed Statistics

  14. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • MOTEUR has no final release version • MOTEUR Simulation use Common JVM Allocated Memory • Insufficient for large scale data flows • WorkFlow GraphicModeling not Malleable • VeryUselessDebugging Platform Problems Encountered

  15. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • Implementation of all WAI checkpoints tests • With CSS parsing • Dynamic scripts parsing • Implementation of GlassFish WebServices in JGASW provider • Implementation of Security Manager Modules to WorkFlow • Defining automation for new processors implementation • Conditioning every modification of the MOTEUR Workflow according to contracts • MOTEUR modeling for neural networks Some improvements

  16. WorkFlow with Modularity Initial WorkFlow More Complex WorkFlow Agenda Project Subject Problems Outlooks Some Tests • What we have learnt : • WorkFlow modeling • Team working and project planning • Facing and resolving unplanned issues • Working on a research-oriented project • Getting along with additional requests from a client

  17. "The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.“ Tim Berners-Lee, W3C Director and inventor of the World Wide Web Thanks for your attention
