1. Introduction & Definitions

This [draft] document is an up-to-date draft specification in RDF of the LRMI 1.1 metadata terms maintained by the Dublin Core™ Metadata Initiative.

In the following term tables, each term is specified with the following minimal set of attributes:

Name: A token appended to the URI of the LRMI namespace to create the URI of the term.
Label: The human-readable label assigned to the term.
URI: The Uniform Resource Identifier used to uniquely identify a term.
Definition: A statement that represents the concept and essential nature of the term.
Type of Term: The type of term—class or property.
Date Issued/Modified: The type of term was created or modified.

Where applicable, the following attributes provide additional information about a term:

Description: Additional information about the term or its application.
Subproperty Of: A property of which the described term is a subproperty.
Equivalent Property: A property to which the described term is equivalent (owl:equivalentProperty).
Subclass Of: A class of which the described term is a subclass.
Equivalent Class: A class to which the described term is equivalent (owl:equivalentClass).
Has Domain: Any resource that has a given property is [inferred to be] an instance of one or more classes (rdfs:domain).
Has Range: The values of a property are [inferred to be] instances of one or more classes. (rdfs:range)
Domain Includes: Relates a property to a class that is (one of) the type(s) the property is expected to be used on. (https://schema.org/domainIncludes).
Range Includes: Relates a property to a class that constitutes (one of) the expected type(s) for values of the property. (https://schema.org/rangeIncludes).
Usage Note: A reference to a resource that provides information on how this resource is to be used. (http://purl.org/vocab/vann/usageNote).

2. Namespaces

The DCMI namespace for formal schemes and schemes of domain and practice communities is http://purl.org/dcx/. Specific community specifications will be in directories appended to the base community namespace. Thus, the http://dublincore.org/lrmi-terms/ URI will always resolve to the latest version of the LRMI terms—i.e., the LRMI properties and classes. The names of the latest version of specific properties and classes are resolved by appending the term to the LRMI base URI—e.g., http://dublincore.org/dcx/lrmi-terms/. Thus, the following term URI examples:

http://purl.org/dcx/lrmi-terms/AlignmentObject
http://purl.org/dcx/lrmi-terms/typicalAgeRange

and (pending CSC proposal from the DCMI/NKOS Task Group (Network Knowledge Organization Systems))

http://purl.org/dcx/nkos-terms/updateFrequency
http://purl.org/dcx/nkos-terms/usedBy

Future controlled vocabularies for LRMI would follow the same namespace pattern. For example, should LRMI create a value vocabulary for use with the lrmi:alignmentType property, the vocabulary might be assigned the URI http://purl.org/dcx/lrmiAlignType/ with individual concepts URI such as http://purl.org/dcx/lrmiAlignType/teaches.

5. Version Changes

This version declares the LRMI 1.1 specification as an RDF schema. As such, it maintains the core property and class intentions of version 1.1 while:

  • Assigning URI to all LRMI 1.1 properties & classes in the /dcx/lrmi-terms/ namespace;

  • Assigning, where appropriate, domains & ranges as well as schema.org domainIncludes & rangeIncludes where support for inferencing is not intended;

  • Declaring, where appropriate, property/class relationships to LOM elements and DCMI classes/properties where appropriate; and

  • Declaring owl:equivalentClass and owl:equivalentProperty relations to schema.org properties & classes.

  • Addition of a missing definition for lrmi:EducationalAudience

7. Schema History

"Co-led by the Association of Educational Publishers --the 501(c)(3) division of the Association of American Publishers-- and Creative Commons, and funded by the Bill & Melinda Gates Foundation and the William and Flora Hewlett Foundation, the LRMI has developed a common metadata framework for describing or 'tagging' learning resources on the web. This framework is a key first step in developing a richer, more fruitful search experience for educators and learners. ... The LRMI was spurred by the announcement in 2011 of Schema.org, a project by Bing, Google, and Yahoo! to create a standard way of tagging online content. ... The metadata schema developed by the LRMI was adopted by Schema.org in April 2013, meaning that anyone who publishes or curates educational content can now use LRMI markup to provide rich, education-specific metadata about their resources with the confidence that this metadata will be recognized by major search engines." — http://www.dublincore.org/about

Work on the LRMI specification began in 2011 with the creation of a LRMI Advisory Board, and a Technical Working Group charged with developing a community-based specification as the education extension for schema.org. Engagement of the broader education metadata community was handled during development through a Google Group. Stuart Sutton, DCMI Managing Director & DC-Education Community co-chair served on the Technical Working Group. Others on the Technical Working Group with close ties to DCMI include Dan Brickley (schema.org) and Phil Barker (Cetis, UK).

The Association of Educational Publishers (AEP) and Creative Commons (CC) have asked that stewardship of the LRMI specification be placed with DCMI at the September closure of Gates funding for LRMI development. From inception, the overall planning for the LRMI specification included the orderly transition of development outcomes from its grant-funded beginnings under the leadership of AEP and Creative Commons to a permanent context managed by an organization with the capacity to provide ongoing stewardship for long-term sustainability, access, and orderly future development. As the funded start-up phase of LRMI was coming to a close, an exploratory team comprised of representatives from AEP, Creative Commons, and the LRMI community was formed and has been actively and systematically engaged in evaluating an array of potential candidates for such stewardship. The exploratory team recommended DCMI because it's open community goals and processes are congruent with those that have emerged within LRMI during its short development history and because of DCMI's reputation and track record in development and principled stewardship of metadata specifications used in the Web context.
