DIGITAL UNIVERSITY PROJECT
Covering
• Background
• Legal Frameworks (students and staff)
• Content Management Solution
• uPortal and Accessibility
• Conclusions
DIGITAL UNIVERSITY PROJECT
The Digital University Project
• Planned over the summer of 2001
• Senior Management buy-in and support
• Flexible structure with cross-institutional steering group
• Two initial development strands
– Institutional web portal
– Web content management
DIGITAL UNIVERSITY PROJECT
First Targets: Students and Staff• Core database applications - Ingres
• Web based email client – IMP
• Library systems - Innovative
• Staff Intranet - home-grown, PERL etc
• VLE/LMS – BlackBoard L1 + Merlin
• External applications - identification
DIGITAL UNIVERSITY PROJECT
Accessibility: Legal Frameworks• United States
– Americans with Disabilities Act– Section 504 & 508 Rehabilitation Act– Section 255 Telecommunications Act
• United Kingdom– Disability Discrimination Act 1995– Special Educational Needs & Disability Act 2001
• European Union– European Employment Directive (by 2006)
• Australia– Disability Discrimination Act 1992– Telecommunications Act 1997
DIGITAL UNIVERSITY PROJECT
In the US…• ADA: right to be able to access and use any facilities
and programs available to other members of the public. • Section 255 of the Telecoms Act: manufacturers of telecom
products and services make them accessible to people with disabilities whenever "readily achievable".
• Rehabilitation Act – Section 504 “reasonable adjustment” in the
workplace– Section 508 of the Rehabilitation Act: Federal Agencies
develop, procure, maintain, or use only those electronic and IT systems which comply with a set of accessibility standards, unless this places an "undue burden" on the Agency.
DIGITAL UNIVERSITY PROJECT
US: WAI/WCAG and s 508
• WCAG Level A (Priority 1) conformant site needs additional work in the 5 areas of– Scripts
– Applets
– Forms
– Navigation
– Timed response feedback
To be s 508 conformant
DIGITAL UNIVERSITY PROJECT
US: WAI/WCAG and s 508
• S 508 conformant site needs additional work in the 4 areas of
– Auditory description of visual track
– Identify changes in natural language of text
– Equivalents for dynamic content
– Clarity of language
To be WAI/WCAG Level A (Priority 1) conformant
DIGITAL UNIVERSITY PROJECT
US case experience
• Access Now/Gumson vs Southwestern Airlines
• Ruling that ADA does not apply to the internet but to specified physical spaces
• Specific rejection of WAI/WCAG specs as not "a generally accepted authority."
DIGITAL UNIVERSITY PROJECT
In the UK
• Special Educational Needs & Disability Act 2001 applies Disability Discrimination Act 1995 to education from Sept 2002
• Institutions should make “reasonable adjustments” enabling access to “student services”
• Disabled students should not be placed at “substantial disadvantage”
• Anticipatory legislation
DIGITAL UNIVERSITY PROJECT
BUT …
“Less favourable” treatment may be justified:
• Maintain academic standards
• Prohibitive cost
• Affects the interests of other students
• Impacts on health and safety
DIGITAL UNIVERSITY PROJECT
In the European Union …
• Community Institutions must “take account” of needs of disabled peopleAmsterdam Treaty - Declaration 22
• “Public sector web sites … must be designed to be accessible to ensure that citizens with disabilities can access information and take full advantage of the potential for e-government.“eEurope Action Plan, Feira Council, June 2000
• EED: "reasonable accommodation" for disabled employees by 2006
DIGITAL UNIVERSITY PROJECT
EU: accessibility & education• Widening participation and Design-for-All
• European Union/European Commission Actions
– Tendering criteria modified to include e-accessibility
– Framework Programme VI modified
– Promotion via WAI-DA project
• Legislative variance across member states
• ESOs identify standards as basis for legislation
DIGITAL UNIVERSITY PROJECT
In Australia• Disability Discrimination Act 1992
– Encourages organisational “Disability Action Plan”
• Telecommunications Act 1997– Universal Service Obligations include equipment
for disabled people
• Funding for consumer groups such as TEDICORE (Telecommunications and Disability Consumer Representation)
• Australian Communications Industry Forum
DIGITAL UNIVERSITY PROJECT
Australian case experience
• Scott vs Telstra 1995• Failure to provide a text telephone ruled
discriminatory
• Maguire vs SOCOG 2000• Sections of web site for Sydney Olympics
inaccessible ruled discriminatory
DIGITAL UNIVERSITY PROJECT
Summary
• UK and EU likely to reference WAI/WCAG Priority Levels
– In legislation (EU)
– In cases (UK)
• US explicit rejection of WAI/WCAG specs
• Australian framework (with active consumer group involvement) actively promoted by EU
DIGITAL UNIVERSITY PROJECT
Content Management: Resolving Chaos
• The Web: it’s not amateur hour anymore
• Web tools by Heinz – 57 varieties of editor
– Technical support nightmare
– Human Resource nightmare
• Accessibility “test case” – any volunteers?
• Aggregating web pages through portal: GIGO
DIGITAL UNIVERSITY PROJECT
Content Management: Solutions• Solution for sites and portal channels
• Caveat: 2 years ago, but watching…
• Almost universally expensive/overpriced
• Frequently inflexible
• Not designed for use by HEI
DIGITAL UNIVERSITY PROJECT
Content Management: Technology• Not “Build or buy, but build and buy”• db solution utilising current licences• Edit basic content within secure web page• Design templates
– XHTML output (now) > XSLT (future)– base design – WAI/WCAG Priority 1– high contrast design – WAI/WCAG Priority 3
• Support rudimentary, but flexible workflow
DIGITAL UNIVERSITY PROJECT
Content Management Process
• Sensitivity to cultures of departments
• “What do you need to do?”
• Information design & architecture first
• Flexible “toolkit” approach
• Clear responsibilities and ownership
DIGITAL UNIVERSITY PROJECT
uPortal and Accessibility: Goals• To create a portal that enables all users
to have equal access to information
• As far as possible enable use without Assistive Technologies (direct access)
• Facilitate access for Assistive Technologies (compatible access)
• Address visual impairments/motor disabilities first
DIGITAL UNIVERSITY PROJECT
Design
• uPortal provides flexibility
• Look and feel
– skins for different visual impairments
• Structural layout
– how the content is presented
• Simplify the portal design
DIGITAL UNIVERSITY PROJECT
Tools/Testing
• Automated tools to check conformance– Bobby – check for WAI/508
• (http://bobby.watchfire.com)
– A-Prompt, LIFT
• Test with assistive technology– e.g. screen readers
• Test with users
DIGITAL UNIVERSITY PROJECT
Look and feel
• Update the CSS and create new graphics
• Two skins
– base – University visual identity
– high contrast – Visual impairments
• Other issues
– font sizes
DIGITAL UNIVERSITY PROJECT
Layout
• Use tab/column default scheme
• edit nested-tables.xsl– webpages/stylesheets/org/jasig/portal/layout/tab-column/nested-
tables
• 4 main sections
– Header, Navigation, Content and Channel
DIGITAL UNIVERSITY PROJECT
• Aggregate all the functionality into one visual layer
• Simplify by removing the tab graphics and login channel
• Screen reader has immediate access to navigation
• Keyboard shortcuts using accesskey attribute
Header & Navigation
DIGITAL UNIVERSITY PROJECT
Header & Navigation – High contrast• nested-tables.xsl checks the skin
<xsl:if test="$skin='hull'">
…. </xsl:if>
<xsl:if test="$skin='hullac'">
<div class="uportal-text-ac2">THE UNIVERSITY OF HULL</div>
<div class="uportal-text-ac">port.hull.ac.uk</div>
</xsl:if>
DIGITAL UNIVERSITY PROJECT
Results• Work in progress
– can be used without assistive technology– access for AT– skin for visual impairment– enabled some keyboard access
• Outstanding – To pass WAI/WCAG Priority 2 needs to
• use a public identifier in a DOCTYPE statement• warn users about pop-up windows or when changing the active window
– Base version also needs to • use relative sizing and positioning (% values) rather than absolute (pixels)
– Section 508• Passes
– Finer grained user choices
DIGITAL UNIVERSITY PROJECT
Issues for portal implementation• Grey areas:
– Resources and links external to institution
– Distance learners
• Aggregated systems presented via portal
– Portal as conformant “wrapper”?
– Presentation oriented web services (WSRP)
