Schema is a way Instructional Designers and educators can tag their content to make it more discoverable. It’s a well-structured, standard metadata scheme.
“Instructional Designers and computers don’t see content in the same way. Where designers see lessons, modules and assessments, computers see headings, paragraphs and sections. Computers can’t see how educational content is different from any other content on the web. Until now.
Using RDF technology, created by Google developers, the OER Schema is made. OER Schema is a vocabulary of terms that define and relate the integral parts shared by OER content across the web. Now, computers can see the lessons, modules and assessments in a way that relates to how Instructional Designers think about OER.”
