  1. AccessForAll 3.0 • Andy Heath, Axelrod Access for All • 28th February 2011 • BSI House, Chiswick, London

  2. I know what you need Personalisation One Size Fits All

  3. I need I need I need Personalisation I need

  4. I need I need I need Personalisation How Machine- readable Preferences I need Adapts To Preferences Standard

  5. AccessForAll (Afa) Simplified (devices can be on both sides) Personal Needs and Preferences PNP Digital Resource Description DRD Matches (selects, gathers adaptations, configures etc.)

  6. AccessForAll (Afa) • UToronto ATRC, IMS Afa 1.0 • -> ISO Individualized Adaptability and Accessibility for eLearning, Education and Training (24751) [ NOTE - NOT education-specific] - Free ISO standard (google 24751 finds it) • -> IMS Afa 3.0 - Public Draft for comment at http://tinyurl/afa3pubicdraft

  7. Afa 3.0 goals • Very simple model • Easily modifiable • XML and RDF bindings - maybe XML for tight control, RDF for modelling and modification • Accessibility knowledge made explicit • Core and Extended

  8. How does it work Poperties and Terms: • DRD AccessMode (visual, auditory, tactile, textual (also textOnImage, colour)), AccessModeAdapted • DRD AdaptationType • DRD HasAdaptation, IsAdaptationOf • DRD AdaptationMediaType (experimental) • PNP AccessModeRequired, AdaptationTypeRequired

  9. For Example • (visual, AccessModeRequired, textual) • For a visual AccessMode in a resource this user requires an AccessMode of textual (for example AudioDesription) • (auditory, adaptationTypeRequired, captions) • For an auditory resource modality • (http://thisResource, hasAdaptation, http://thatResource • thisResource has an adaptation identified as thatResource

  10. Relationships Etc.. Etc..

  11. Refinement • An element or term can refine another (be a more-precise form of), similar to Dublin Core

  12. Terms and Properties • Modelled in harmony with ISO Metadata for Learning Resources - a very new Metadata Standard - Framework document complete, other parts approaching FDIS • You get a set of Properties and terms - freely use what you wish, add your own (but we recommend Core or Extended set (see the specification)

  13. Afa3.0 Key Elements

  14. Afa3.0 Key Elements

  15. Please • Look it over • Try it out, implement it, check it works, tell us what doesn’t work • Think about modelling the relations between terms • Do we need community ontologies • What formalism(s) ? • Accept our thanks • The IMS Accessibility SIG • http://www.imsglobal.org/accessibility/ • Afa3.0 Public Draft for comment • http://tinyurl.com/afa3publicdraft
