Description:	The LRMI™ specification is a collection of classes and properties for markup and description of educational resources. The specification builds on the extensive vocabulary provided by Schema.org and other standards.

Specification version 1.1

Version 1.1 is the final version of the LRMI Metadata Specification created by the LRMI Project between 2011-2014 and transferred to DCMI in 2014. This version is retained as it was in 2014; newer terms are are to be found in the current specification of LRMI Terms in RDF.

AEP Press Release on transfer of stewardship of LRMI to DCMI.

The LRMI™ specification is a collection of properties to describe educational resources. It builds on the extensive vocabulary provided by Schema.org. Predominantly it uses properties of resources of type schema.org/CreativeWork that were proposed to Schema.org by the LRMI to describe the educational characteristics of learning resources. For some of these properties it uses the LRMI-created types schema.org/AlignmentObject and schema.org/EducationalAudience.

The LRMI project looked for inspiration, ideas, and learnings from other projects with similar visions in furtherance of its goal of interoperating with other specifications. As much as possible, contributors on those works were invited to participate in LRMI specification development. We wish to acknowledge and thank these initiatives for informing our work:

Table 1. LRMI Additions to Schema.org/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"
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: "PT30M" Ex: "PT1H25M"
typicalAgeRange	schema.org/Text	The typical range of ages the content’s intended end user. Ex: "7-9" Ex: "18-"
interactivityType	schema.org/Text	The predominant mode of learning supported by the learning resource. Acceptable values are active, expositive, or mixed. Ex: "active" Ex: "mixed"
learningResourceType	schema.org/Text	The predominant type or kind characterizing the learning resource. Ex: "presentation" Ex: "handout"
useRightsUrl	schema.org/URL	The URL where the owner specifies permissions for using the resource. Ex: http://creativecommons.org/licenses/by/3.0/ Ex: http://publisher.com/content-use-description
isBasedOnUrl	schema.org/URL	A resource that was used in the creation of this resource. This term can be repeated for multiple sources.

A note on useRightsUrl: this property was not adopted by schema.org. Subsequently schema.org adopted a property called license which encompasses the same functions as useRightsUrl (see below). The license property is likely to be more widely understood by consumers of schema.org mark-up than the LRMI useRightsUrl property.

Table 2. Other important characteristics of learning resources that are covered by Schema.org properties of CreativeWork
Property	Expected Type	Description
name	schema.org/Text	The title of the resource.
about	schema.org/Thing	The subject of the content.
dateCreated	schema.org/Date	The date on which the resource was created.
author	schema.org/Person	The individual credited with the creation of the resource.
publisher	schema.org/Organization	The organization credited with publishing the resource.
inLanguage	schema.org/Language	The primary language of the resource.
accessibilityAPI	Text	Indicates that the resource is compatible with the referenced accessibility API. (WebSchemas wiki lists possible values).
accessibilityControl	Text	Identifies input methods that are sufficient to fully control the described resource. (WebSchemas wiki lists possible values).
accessibilityFeature	Text	Content features of the resource, such as accessible media, alternatives and supported enhancements for accessibility. (WebSchemas wiki lists possible values).
accessibilityHazard	Text	A characteristic of the described resource that is physiologically dangerous to some users. Related to WCAG 2.0 guideline 2.3. (WebSchemas wiki lists possible values).
license	Url or CreativeWork	A license document that applies to this content, typically indicated by URL.
