DCMI: Serialization Examples of LRMI/Schema.org Markup

LRMI Logo

Below you will find examples of schema.org markup of learning resources using LRMI properties and types. Each example begins with simple HTML markup of a learning resource as you might find on the Web. The HTML markup is followed by semantic markup using LRMI types and properties in three of the most common serializations: (1) Microdata, (2) RDFa, and (3) JSON-LD.

The canonical versions of these examples can be found as annotations to the properties and classes on the schema.org website.
