Overview

The Learning Registry is an effort jointly sponsored by the Department of Education and the Department of Defense. The effort began in 2010 and creates a set of technical protocols for the exchange of data in support of educational goals by multiple providers. It is not a portal, but a platform for aggregating metadata and other data about learning objects. 

NSDL Publishes to the Learning Registry

NSDL publishes its learning object metadata to the Learning Registry in LRMI/JSON-LD format and paradata in LR paradata 1.0 format.  Additions, changes, and deletions are published on a weekly basis.

The NSDL first published a static snapshot of its metadata to the Learning Registry in NSDL DC format in 2011. These were superseded in November 2013 when NSDL began publishing using LRMI/JSON-LD and LR paradata 1.0 formats.

 As of November 2013:

• Approximately 120 NSDL partner collections published
• 125,181 metadata records published in LRMI/JSON-LD format
• 21,932 records published in LR Paradata 1.0 format 
• Resources aligned to education standards using ASN URIs (a current breakdown of NSDL standards alignments can be viewed here: http://nsdl.org/search/standards/):
  • 2847 - Resources aligned to Common Core Math Standards
  • 172 - Resources aligned to Common Core ELA Standards
  • 2819 - Resources aligned to AAAS Benchmarks (2008 version)
  • 2532 - Resources aligned to AAAS Benchmarks (1993 version)
  • 5297 - Resources aligned to National Science Education Standards
  • 88 - Resources aligned to Next Generation Science Standards

Learning Resource Metadata

Learning resource metadata are published in LRMI/JSON-LD format and include standards tagged with ASN URIs, CCSS URIs, CCSS dot notation, and other standards identifier schemes; Grade Level (typicalAgeRange), Audience, Resource Type, and others.

Background

NSDL has been collaboratively engaged with the Learning Registry from its inception, along with additional collaborators, Butte County Office of Education/CADRE, Navigation North, and others.

• See the STEM Exchange Progress Report April 2011 for more information about NSDL interactions with the Learning Registry
• NSDL hosted the Learning Registry Plugfest 2 in December 2011 at the University Corporation for Atmospheric Research (UCAR) Center Green Laboratory
