...via schema.org collaboration...

• DCMI established in 1995• Globally recognized metadata

schemas for web resource discovery

• LRMI development started in 2011 as the education extension for schema.org

• In October 2014, stewardship of LRMI was transferred to DCMI by AEP & Creative Commons.

• DCMI/LRMI Task Group to manage further development of LRMI specification.

Web Schemes & Schemas

Agenda...• Transfer of LRMI metadata specification• Machine-actionable core value vocabulary development• Improving LRMI implementer documentation• Guidance & Best Practices

– Educational Framework development– Education community and application metadata profiling with LRMI– Managing intersection of closed systems & the open world of the Web

Transfer of LRMI metadata specification...LRMI Task Group: Work Package #1 (October 2014)

Formalization of LRMI the schema

1. Transfer of official LRMI schema specification from lrmi.net to dublincore.org

http://dublincore.org/dcx/lrmi-terms/

2. Creation of an RDF schema to support long-term curation, further development and long-term availability of the spec.

3. Publication of the LRMI schema in various serializations:• JSON-LD• RDFa• Microdata• RDF/XML• Turtle/N3

4. Formal mapping of the LRMI schema to the schema.org schema

Machine-actionable value vocabulary developmentLRMI Task Group: Work Package #3

LRMI ‘core’ value vocabularies...Development goals1. “Core” as opposed to fine-

grained vocabularies2. Extensible (regional, local,

organizational refinements)3. Standard vocabulary description

language– W3C’s Simple Knowledge Organization

System (SKOS)

4. Multilingual support5. Web resolvable identifiers (URI)

returning machine actionable data for

6. Normalized (international) definitions

Initial core vocabularies• Educational Audience Role• Learning Resource Type• Educational Use• Alignment Type

Development Process• DCMI/LRMI Task Group• Open community comment

(LRMI Google Group)• Publication of human readable &

machine actionable vocabulary versions (JSON-LD, RDFa, Microdata)

• Registration of vocabularies with public registries (e.g., Linked Open Vocabularies (LOV))

LRMI Core Value Vocabularies

Best practice development & publication...LRMI Task Group

Initial areas of best practice development...• How to locally...

– Develop, use (and publish) “Educational Frameworks” in describing learning resources using machine-actionable mechanisms amenable to the open Web...

– Develop machine-actionable metadata profiles to support sharing at “community” and “application” levels...

– Handle the interface between the closed world of our systems and the open Web (e.g., “Unique Identifier Assumptions”)...
