EUROPEAN UNION
WEB ACCESSIBILITY
OBSERVATORY

Background: European Union
Completed :
•
WAB Cluster
• EIAO: Large scale accessibility benchmarking service
• BenToWeb: EARL, WCAG 2.0 Test suites
• Support-EAM: a European accreditation system
• CEN Workshop Agreement
Continuing:
• Euracert Quality Label
•
e-Accessibility thematic network (scope is more than web –
awarded? )
•
eGovernment Monitor Network (eGovMoNet) (scope is more
than web accessibility)
9
Ideas for the Project
Scope:
1.
Provide ongoing Automated Web Accessibility
Conformance testing
2.
Continuous Improvement of : Methods, Metrics, Tests,
Tools
3. Verify “quality” of tools and results(are results reliable?)?
4. Provide access to verified? tools to: Partners, Public?
5. Serve as a meeting place for (or pointer to?) news,
information and discussion.
10
Summary:
Using the best tools available at the time, provide actionable data on
the state of "web accessibility" in the EU in a timely and ongoing
manner so that decision makers are properly informed.
11
Strategy
Use a “loosely coupled” tool chain of Crawler(s?), Validator(s),
Report Generator(s), Archiver.
•
•
•
•
Use the Best of breed
Allow for updating, testing, comparison, migration.
Plan for migration to the future.
Provide “hooks” for 3rd party tools and assistance for manual
testing
12
Rational:
A “loosely coupled” tool chain allows for:
•
•
•
•
INCLUSION of those that meet requirements
•
Opens opportunities for cooperation and sharing
More adaptability
Easier updating, testing, research, migration.
Facilitates the Integration of other needs such as Spanish
“sexist language”.

Challenges
Moving “Web Accessibility” requirements
•
Experience highlights current shortcomings (HTML5)
Conformance testing follows laws and standards
Additional Local Requirements (e.g. Sexist Language)
•
Harmonisation “plus”
Continuous conformance Testing
Continuous TOOL Testing.
