  1. 1. Harmonizing WCAG Conformity Assessment Method Session WEB-036 CSUN 2012
  2. 2. Harmonizing WCAG Conformity Assessment Method Authors• Dominique Burger : BrailleNet association, presidentContact : dominique.burger@upmc.fr• Jean-Pierre Villain : Qelios company, technical directorContact : jpvillain@yahoo.fr• Denis Boulay (speaker) : BrailleNet association, AccessiWeb directorContact : denis.boulay@accessiweb.org
  3. 3. Harmonizing WCAG Conformity Assessment Method We are from here
  4. 4. Harmonizing WCAG Conformity Assessment Method Content of the session• Presentation of the WCAG CAC (Conformity Assessment Cohenrence) project• Description of a list’s management tool• Demonstration of the tool prototype
  5. 5. Harmonizing WCAG Conformity Assessment Method WCAG 2.0 is the universal reference for Web Accessibility• Europe : Communication "Towards an accessible information society" (1.12.2008)• France : Law on the rights of people with disabilities – Article 47 : accessibility of public online services (11.02.2005) Creation of an e-accessibility checklist (RGAA) based on WCAG 2.0 (23.10.2009)
  6. 6. Harmonizing WCAG Conformity Assessment Method Demand for independent conformity assessmentThird Party Certification• Quality Marks : • Assessment methods • Checklist • Single tests• Certification Process
  7. 7. Harmonizing WCAG Conformity Assessment Method Several schemes have emerged• Belgium• France• Italy• Spain• UKAll refering to WCAG2.0 !It works locally in different countries
  8. 8. Harmonizing WCAG Conformity Assessment Method Practical questions• Do they really cover 100% WCAG2.0 ?• Do they provide additional information ?• What correspondences between them ?• Do they tell the same story about Web sites ?• Is it possible to certify in one country using a scheme developed in another ?
  9. 9. Harmonizing WCAG Conformity Assessment Method WCAG Conformity Assessment Coherence - Phase 1• Sample pages (32) covering all WCAG AA• Evaluation by experts according their checklists• Comparison of the results• Descriptive Questionnaire to learn more about each checklist and assessment methods
  10. 10. Harmonizing WCAG Conformity Assessment Method WCAG Conformity Assessment Coherence - Phase 2Development of a tool :• Model of Data• Proof of concept
  11. 11. Harmonizing WCAG Conformity Assessment Method The project has two main objectives Analyse Use1. Provide analysis tools to assure 1. Provide tools for the expert in the relation between : order to : 1. a checklist to WCAG 1. adapt a checklist to a web 2. a checklist to another project checklist 2. use several checklists for a 3. several checklists to WCAG same web project 4. several checklists to one 3. Facilitate maintenance and checklist update of checklists
  12. 12. Harmonizing WCAG Conformity Assessment Method WCAG CAC project Objective : provide a common recognition scheme based on multiple checklistsUWEM (Unified Web Evaluation Methodology) Solution Common checklist Allow to : 1. Choose a working checklist (eg. AW) Lowest common denominator 2. Choose targeted checklists Not adapted to checklists, practices and tools used locally Obtain a version of your working checklist adapted to the constraints and requirements of all targeted checklists Rarely used
  13. 13. Harmonizing WCAG Conformity Assessment MethodThe expert, his working checklist and a web project Objective : work only on what is useful Problem Solution A checklist covers all possible cases Allow to : 1. Adapt a checklist : 1. Only useful elements 2. add personalized criteria, key- A lot of « noise » due to the words, modify the structure unnecessary criteria presence in the context of the project Obtain a version of its working Increase of the expert work checklist really adapted to theMore complexity in the results analysis targeted project
  14. 14. Harmonizing WCAG Conformity Assessment Method Problem Checklists have different structures Checklists Nb of elements Description Notes WCAG 2.0 4 Principle Guideline Success criterion Techniques AccessiWeb 2.1 4 Thematic Criterion Test Conditions AnySurfer 2 Bloc Guideline Abilitynet 1 Success criterionTechnosite/MEWA 1 Criterion UWEM 2 4 Principle Guideline Success criterion Techniques
  15. 15. Harmonizing WCAG Conformity Assessment Method ProblemThe relationship to WCAG is established via a measuring level belonging to each checklist Checklists Nb of elements Description Notes WCAG 2.0 4 Principle Guideline Success criterion Techniques AccessiWeb 2.1 4 Thematic Criterion Test Conditions AnySurfer 2 Bloc Guideline Abilitynet 1 Success criterion Technosite/MEWA 1 Criterion UWEM 2 4 Principle Guideline Success criterion Techniques

  18. 18. Harmonizing WCAG Conformity Assessment Method The constraint of the Data Model A unique measuring level A one-to-one relationship with WCAG Case of AnySufer A measuring level is defined by :Original structure : 1. A main success criterion- Bloc 2. One or several additional - Guideline (mesuring level) success criteria - Critère (mesuring level)"Rectifying" structure The relationship with WCAG is- Bloc defined by the main success - Guideline (mesuring level) criterion
  19. 19. Harmonizing WCAG Conformity Assessment Method Model of correspondence request Requests1. Fusion (Request « Via ») : to mix the checklists2. Comparison (Request « Vs ») 1. Completion : add informations 2. Difference : remove information
  20. 20. Harmonizing WCAG Conformity Assessment Method Example for request « Via » Resulting structureCommon structure N N1 WCAG N N1 AW 2.1 N2 N2 Via N AW 2 N3 WCAG N1 N4 N2 N3 N4
  21. 21. Harmonizing WCAG Conformity Assessment MethodExample of a complex Resulting structure request N Common structure AW 2.1 N1 AW 2.1 N N2 N1 + N2 RGAA RGAA AnySurfer N2 N2 N3 + N3 AnySurfer AW 2.1 N4 N4The request displays AccessiWeb 2.1 checklist with, for each test, all RGAA and Anysurferchecklist’s tests to add : all those who have no correspondence with AccessiWeb 2.1checklist
  22. 22. Harmonizing WCAG Conformity Assessment Method Prototype 1. Validate the data model 2. Elaborate the requests engine 3. Testing all the requestsPhase 1 : simple case Phase 2 : more complex cases Checklist Checklist Checklist Checklist Checklist Checklist WCAG WCAG Checklist CAC
