INTECO 2

Web Accessibility Audit Public Administration Websites accessibility audit • Accessibility requirements of the Spanish Standard UNE 139803. • • Inclusion of solutions for the problems identified. Technical and executive summaries. Monitoring reports / Periodic reviews • • Analysis done based on previous reports. Tracks the tasks performed for correction and improvement. 3

Web Accessibility Monitor • • Based on WCAG 1. 0 • • Twice per year (three so far) 30 Public Web sites studied in three segments Sample of 10 pages per site (25 in the first and the second year) • Accessibility check: • Level I: 11 points tested (Level I for WAI-A) • Level II: 10 points tested (Level I + II for WAI-AA) • Analysis of the results • Data consolidation • Comparison charts • Global evaluation • Conclusions 4

INTAV: INTECO Accessibility Validator • Automatic Web Accessibility Checker using WCAG 1. 0 and UNE 139803 standards. • Alerts the webmaster when there are changes in the accessibility level of a website. • Integrated with the INTECO’s web crawler. 5

Web Accessibility Audit Reports Solutions Advices Requirements Justification Problems 6

LENOX: Proper Language Use Analyzer • • Semantic Web analyzer for the use of sexist language. • Integrated with the INTECO’s web crawler. Alerts the webmaster when sexist terms are added to a website (only in Spanish). 7

EUROPEAN UNION WEB ACCESSIBILITY OBSERVATORY 8

Background: European Union Completed : • WAB Cluster • EIAO: Large scale accessibility benchmarking service • Ben. To. Web: EARL, WCAG 2. 0 Test suites • Support-EAM: a European accreditation system • CEN Workshop Agreement Continuing: • • Euracert Quality Label • e. Government Monitor Network (e. Gov. Mo. Net) (scope is more than web accessibility) e-Accessibility thematic network (scope is more than web – awarded? ) 9

Ideas for the Project Scope: 1. Provide ongoing Automated Web Accessibility Conformance testing 2. Continuous Improvement of : Methods, Metrics, Tests, Tools 3. 4. 5. Verify “quality” of tools and results(are results reliable? )? Provide access to verified? tools to: Partners, Public? 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 3 rd 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”. 13

Opportunities Archive • • Pages (selection/all) Results by Tool/page Research • • Portal tool Fingerprinting DOM Fingerprinting 14

Some Accessibility Validators: how “valid”? http: //www. totalvalidator. com/ http: //www. tawdis. net/ http: //wave. webaim. org/ http: //accessibility. egovmon. no/en/ http: //achecker. ca/checker/index. php http: //valet. webthing. com/access/url. html http: //rastreador. inteco. es/intav. Home. Action. do http: //validator. nu/ http: //www. sidar. org/hera/ 15

Crawlers Harvestman crawler: http: //code. google. com/p/harvestman-crawler/ Heritrix [Internet Archive] : http: //crawler. archive. org/ Nutch based [e. g. INTECO]: http: //lucene. apache. org/nutch/ Bixo [Apache Hadoop cluster, Cascading ] : http: //bixo. 101 tec. com/about/ Bixolabs [Bixo in Amazon’s Elastic Compute Cloud (EC 2) ]: http: //bixolabs. com/ D-Harvestman [dead? ] http: //sourceforge. net/projects/dcrawler/ 16

Challenges Moving “Web Accessibility” requirements • Experience highlights current shortcomings (HTML 5) Conformance testing follows laws and standards Additional Local Requirements (e. g. Sexist Language) • Harmonisation “plus” Continuous conformance Testing Continuous TOOL Testing. 17
