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

Page 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>

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

Page 18

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
