This is an archived WebSchemas proposal Learning Resources (LRMI) schema for schema.org. See Proposals listing for more. Note: active schema.org development is now based at github


The Learning Resources Metadata Initiative has drafted a set of terms to improve schema.org's use with educational materials. This Learning Resources schema is the product of that LRMI initiative. See the LRMI site for detailed design discussions, related work and supporting materials.


This schema add two new types:

1) AlignmentObject, inherited from Intangible.

Properties from AlignmentObject
alignmentType Text A category of alignment between the learning resource and the framework node. Recommended values include: 'assessed', 'teaches', 'requires', 'textComplexity', 'readingLevel', 'educationalSubject', and 'educationLevel'.
educationalFramework Text The framework to which the resource being described is aligned.
targetDescription Text The description of a node in an established educational framework.
targetName Text The name of a node in an established educational framework.
targetUrl URL The URL of a node in an established educational framework.

2. EducationalAudience, inherited from Audience

Properties from EducationalAudience
educationalRole Text The role that describes the target audience of the content.

The schema mainly adds new properties (typically but not necc. on CreativeWork):

Property Expected Type Description
educationalAlignment schema.org/AlignmentObject An alignment to an established educational framework.
educationalUse schema.org/Text The purpose of the work in the context of education.
  • Ex: "assignment"
  • Ex: “group work”
interactivityType schema.org/Text The predominate mode of learning supported by the learning resource. Acceptable values are active, expositive, or mixed.
  • Ex: "active"
  • Ex: "mixed"
isBasedOnUrl schema.org/URL A resource that was used in the creation of this resource. This term can be repeated for multiple sources.
learningResourceType schema.org/Text The predominate type or kind characterizing the learning resource.
  • Ex: "presentation"
  • Ex: "handout"
timeRequired schema.org/Duration

(ISO 8601)

Approximate or typical time it takes to work with or through this learning resource for the typical intended target audience.
  • Ex: "P30M"
  • Ex: "P1H25M"
typicalAgeRange schema.org/Text The typical range of ages the content's intendedEndUser.
  • Ex: "7-9"
  • Ex: "18-"

Example Markup

This example is based on a resource available at Connexions. Highlighted lines are those corresponding to LRMI-only terms.
