So, why do we need a standard?
Page 14 14
Goal: Make it easier and more convenient to find learning resources that meet specific student and class needs.
Curriculum Standards
Schema.org
Intersection of three opportunities
Resource Registries (Learning Registry)

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 23
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
