This document discusses using Schema.org metadata and the Learning Resource Metadata Initiative (LRMI) specification to improve the discoverability of accessible educational resources. It provides examples of how accessibility properties could be added to Schema.org metadata for books, web pages, videos, and images. The goal is to allow users to more easily find learning materials that meet their needs, such as filtering search results by the presence of image descriptions or closed captions. The accessibility metadata proposal was developed through an open working group and is being explored for adoption by organizations like the Learning Registry and EPUB. Upcoming improvements to search filters on sites like Free.Ed.Gov aim to leverage this metadata.

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>

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

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
– Released under a Creative Commons BY-SA License
