3. A centre of expertise in digital information managementwww.ukoln.ac.uk Common Assumptions (1) Things we should have in common: A desire to see widely-accessible and interoperable services Use of open standards to provide platform and application-independent services A recognition of the challenges faced within the sector in achieving these aims (funding, time scales, expertise, user requirements, …) A desire to provide advice on how to achieve the aims whilst acknowledging the challenges Background

4. A centre of expertise in digital information managementwww.ukoln.ac.uk Common Assumptions (2) We also recognise that: The W3C is the authoritative body which is driving the development of Web standards W3C WAI has driven the agenda for Web accessibility W3C WAI has been successful in raising awareness globally that: Digital resources can be made accessible Digital resources should be made accessible Background

5. A centre of expertise in digital information managementwww.ukoln.ac.uk My Activities In The Area My activities include: Attended the public launch of W3C WAI at the International WWW conference Representing JISC on the W3C Organising an accessibility panel session at WWW 2003, Budapest (with Judy Brewer & Wendy Chisholm, W3C, myself and Jenny Craven, CERLIM, MMU) Joint participation with TechDis in workshops for FE sector Joint paper with Lawrie Phipps, following recognition of shared views on approaches for implementing best practices Background

6. A centre of expertise in digital information managementwww.ukoln.ac.uk UK HE Web Sites (1) In Sept 2002: Article based on survey of 164 UK HEI home page published in Ariadne e-journal Survey used Bobby and reported on errors capable of being detected automatically Four sites seemed to comply with WAI AA – but only 3 did comply 70 complied with WAI A Challenges Community is aware of WAI, SENDA, … and seeks to implement best practices. Subsequent discussion led to concerns over whether WAI AA guidelines were achievable / desirable

7. A centre of expertise in digital information managementwww.ukoln.ac.uk UK HE Web Sites (2) Following survey publication one Web manager said: "I too have been struggling with just how rigorously the WAI guidelines should be implemented … I certainly aspire to comply as full as I can with the WAI guidelines but …" Some guidelines are too theoretical I will have a pragmatic approach: Will use tables for positioning Will not associate form controls for search boxes Will not necessarily nest headers correctly … Concerns These are seen as WAI requirements. Are they? Challenges

8. A centre of expertise in digital information managementwww.ukoln.ac.uk Accessibility & E-Learning E-learning accessibility provide additional challenges: It is intended to make information resources easy to access; in learning students may be expected to engage in thinking Specific problems encountered include: Providing images and asking students what they have in common (ALT text gives the game away) Environments with well-liked drag and drop interfaces (how to make this accessible without a mouse) 3D visualisation, … Challenges

9. A centre of expertise in digital information managementwww.ukoln.ac.uk WAI Guidelines Some thoughts on the WAI WCAG guidelines: The A / AA / AAA guidelines: AAA is for Oxbridge / A for the FE sector A addresses most areas of disability -> AAA unusual disabilities A addresses aspects which can be dealt with using today’s mainstream technologies; AAA with future XML browsers … WAI guidelines address accessibility issues and promote W3C standards WAI guidelines ignore wider IT issues (out-of- scope for them) Challenges

10. A centre of expertise in digital information managementwww.ukoln.ac.uk Accessibility Beyond The Web W3C WAI: Raised awareness of accessibility issues Ideas taken onboard by others: OS Vendors (accessibility aids in Windows XP) Application vendors such as Adobe PDF) and Macromedia (Flash) The response from the market place means it is not longer true to say (for example) that fixed font sizes can’t be resized (Windows XP now allows this, as does Opera) Web accessibility could be regarded as a subset of IT accessibility Challenges

11. A centre of expertise in digital information managementwww.ukoln.ac.uk WAI W3C WAI are a very successful body But are they too blinkered? They promote W3C standards … but should this be in the remit of an accessibility body Accessibility of proprietary formats, OSs, etc. is outside their remit Unsuccessful engagement in addressing such issues at WWW 2003 - see W3C privacy work provided technical framework and delegated implementation, policies to community. Why isn’t this approach being used by WAI? Challenges

12. A centre of expertise in digital information managementwww.ukoln.ac.uk Background To QA Focus QA Focus: JISC-funded project to help ensure JISC’s digital library programmes are functional, inter-operable and widely accessible Approach based on development of a quality assurance methodology Approach is developmental and based on: Documented policies Systematic processes for ensuring compliance Have developed matrix for selection of standards Peer-reviewed conference papers published See Solutions

13. A centre of expertise in digital information managementwww.ukoln.ac.uk Standards Selection Matrix QA Focus has developed a selection for selection of standards: Open standards are good, but some can be immature, expensive too use, fail to be deployed Proprietary formats are deprecated but some can be well-established (PowerPoint), provide low- costs solutions, become more open (Flash/SWF), be perceived as open (Java), … QA Focus selection matrix: Seeks to addresses these (and related) issues in a systematic way Can be deployed by (a) third party checking (cf. NOF-digi) (b) peer review or (c) self-assessment Solutions See

14. A centre of expertise in digital information managementwww.ukoln.ac.uk Quality Assurance QA Focus has developed a QA methodology: Documented policies, including policy, architecture and exceptions: Systematic procedures for ensuring policies are implemented (and underlying causes addressed) Solutions Web Standards: Policies Policies: Compliant XHTML 1 and CSS 2 Architecture: Save from MS Word / Zope CMS Exceptions: HTML files derived from MS Office files Web Standards: Procedures Compliance checking:,validate and,cssvalidate used after page created. Monthly batch validation Audit trail: Batch audit trail & notes published

15. A centre of expertise in digital information managementwww.ukoln.ac.uk Accessibility Policies What type of accessibility policies could be applied: The Web site will comply with WAI AA But scope, feasibility, compliance checking, … The institution has a policy on accessibility. We seek to ensure … On the Web site we will seek to comply with appropriate WAI guidelines, accessibilities guidelines and … Relates to wider accessibility policies. Recognises wider Web issues. But danger of being too woolly, unless advice on implementation and compliance checking measures provided Solutions

16. A centre of expertise in digital information managementwww.ukoln.ac.uk Accessibility Procedures If a QA methodology is adopted we need to define compliance checking procedures: Use Bobby: no! Use a range of automated tools: still over- emphasises problems capable of automated detection Better approaches should probably address usability and accessibility: Usability and accessibility testing regime when new services deployed Simple batch automated accessibility / standards compliance checking to spot workflow errors Tools for user feedback and procedures for responding to feedback Solutions

18. A centre of expertise in digital information managementwww.ukoln.ac.uk Accessibility Strategies Some thoughts on e-learning accessibility strategies: Can we not seek an accessible learning environment, even if the e-learning environment may be in-accessible? Is just-in-time accessibility an option rather than just-in-case accessibility, especially in difficult areas such as 3D visualisation, etc. Is accessible Flash, PDF... an option (RNIB’s / BECTa’s view?) or does the open standards card trump this? Should we (JISC) mandate this view or seek to persuade others but leave it to them to decide? Isn’t the term “e-learning accessibility” misleading – shouldn’t be refer to “e-learning usability (and accessibility) Issues

19. A centre of expertise in digital information managementwww.ukoln.ac.uk WAI WCAG 2.0 The updated WAI WCAG guidelines 2.0 are now available: Should JISC give an official response when these are voted on?
