13. 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
