  10. How it Works – Schema.org Schema.org metadata describes ‘things’ on the web as agreed upon by the major search engines to improve search & discoverability

  11. Recipe Metadata Example <div itemscope itemtype="http://schema.org/Recipe"> <div itemprop="nutrition” itemscope itemtype="http://schema.org/NutritionInformation"> Nutrition facts: <span itemprop="calories">240 calories</span>, </div> Ingredients: - <span itemprop="ingredients">3 or 4 ripe bananas, smashed</span> - <span itemprop="ingredients">1 egg</span>

  12. Learning Resources Metadata

  13. Goal: Make it easier and more convenient to find learning resources that meet specific student and class needs. Curriculum and Accessibility Standards Resource Registries (Learning Registry) Schema.org Why Now? Kinda’ Perfect Storm Intersection of three opportunities LRMI from a representation by Brandt Redd, Gates Foundation

  14. The LRMI Properties v1 (lrmi.net/the-specification) • General Terms (Schema.org): • title/name • URL • Description • Image • Topic • created (date) • Creator • Publisher • inLanguage • Mediatype • technologiesRequired • technologiesRecommended • Use RightsURL • is based on • Educational Terms: • intendedEndUserRole • educationalUse   • timeRequired • typicalAgeRange   • interactivityType   • learningResourceType • Competency related: • educationalAlignment • Description • URL • Alignment Type • educationalFramework • targetDescription • targetName • targetURL

  16. What About Accessibility? Addressing the needs of ALL Students Discover Learning Resources based on disability needs and learner preferences • Compatible with AT, WCAG guidelines • Leverage MathML, tactile graphics and image descriptions • Have closed-captioned video

  17. Leveraging Access For All • Gates Foundation funded Benetech to develop a Schema.org proposal for Accessibility Metadata that would be complementary to LRMI • Benetech assembled a broad Working Group of experts • AEP (LRMI), APH, Dublin Core, EDItEUR (ONIX), Gooru Learning, IMS Global, IDRC, NCAM, SRI (Learning Registry) • Proposal submitted to Schema.org in April 2013 • Influenced heavily by IMS Global Access for All • Released under a Creative Commons BY-SA License
