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
Page 10

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>

17. 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 17

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 accepted by Schema.org in November 2013
– Influenced heavily by IMS Global Access for All
– Released under a Creative Commons BY-SA License
