IOER Metadata and Vocabularies

Last Updated 10/29/2015

IOER Metadata is based on:

  • Learning Resource Metadata Initiative (LRMI) schema version 1.1
  • The LRMI 1.0 was adopted by Schema.org (SCH).
  • Additional metadata has been introduced and potential exists for additional needs to be added over time. LRMI seeks to have SCH adopt any new schema.
  • Learning Registry (LR)
  • NSDL Learning Application Readiness (LAR)
  • Vocabulary used by IOER mirrors that of the federal Common Education Data Standards (CEDS)
  • Race to the Top State Support (RttT)
  • JSON-LD

ISLE
Conditions that govern the user’s ability to access (viewing, downloading, etc.) the Resource.
Free Access
The right to view and/or download material without financial, registration, or excessive advertising barriers.
Free Access with Registration
The right to view and/or download material without financial barriers but users are required to register or experience some other low-barrier to use.
Limited Free Access
Some material is available for viewing and/or downloading but most material tends to be accessible through other means.

The right to view, keep, and/or download material upon payment of a one-time fee.
Available by Subscription
The right to view and/or download material, often for a set period of time, by way of a financial agreement between rights holders and authorized users.
Usage Rights
useRightsUrl or license
LRMI (useRightsUrl), Schema.org, LRMI (license)
Creative Commons
Conditions that govern the allowed use, modification, and/or redistribution of the Resource.

Note: According to the LRMI specification page, useRightsUrl was not adopted by schema.org. Subsequently schema.org adopted a property called "license" which encompasses the same functions as useRightsUrl. The license property is likely to be more widely understood by consumers of schema.org mark-up than the LRMI useRightsUrl property.

Note: Media Type was included in an earlier version of the LRMI schema (as "mediaType"). It was removed in the current version. An equivalent property, "Format", exists in the Dublin Core schema, which is also used by the NSDL_DC and LAR schemas. There does not appear to be a clear equivalent to this property within Schema.org, as Schema.org defines many properties that would be equivalent to some aspect or subset of this property. This property is still in use by the OER system.

Grade Level
alignmentObject.educationalFramework and typicalAgeRange
LRMI, ISLE (see Note)
ISLE unless otherwise noted
The US K-12 Grade(s) and/or Postsecondary educational audience that the Resource is intended for.

Note: Wherever possible, the OER system translates between typicalAgeRange and grade level (as defined by US schools). The typicalAgeRange property does not adequately address postsecondary, technical, or adult education. However, grade level does not exist in LRMI. Grade level as used by the OER system is derived from the NSDL_DC/LAR implementation of "Education Level", adjusted for US schools. The OER system publishes both grade level and typicalAgeRange where possible, and understands either when importing data.

LRMI Schema Extensions

The following extensions to the LRMI schema are required to handle ISLE needs:

Description
Metadata tag: "description"
Adequately expressed in schema.org as "description" - a part of "Thing" which is the most generic type of item.
Also present in LAR, LOM, NSDL_DC, and Dublin Core.
Free-text to describe a Resource
Group Type
Metadata tag: "groupType"
Not in schema.org, NSDL_DC, or LAR.
Defines the intended size of the group for which a Resource is meant
Access Rights
Metadata tag: "accessRestrictions"
Not in schema.org.
borrowed from NSDL/LAR (LAR calls it "accessRestrictions" while NSDL_DC calls it "accessRights"). Different from Usage Rights.
Defines the cost/requirements associated with accessing a Resource
NSDL_DC Definition: Information describing conditions or requirements for viewing and/or downloading the material.
LAR Definition: Information about a user's access to a resource in regards to conditions or regulations imposed by the rights owner.
NSDL_DC and LAR use the same controlled vocabulary with one exception: NSDL has "Free Access with Registration" while LAR has "Free Access with User Action" - These are nearly identical with LAR having the broader definition.
Instructions & Equipment Requirements
Metadata tag: "requires"
ISLE Extension
"dct:requires" is a part of NSDL_DC and Dublin Core,.
Not a part of LAR or schema.org.
Free-text to describe any equipment, hardware, instructions, materials, etc., necessary to use a Resource
Career Clusters
Metadata tag: "careerCluster" with properties for "country" and "region" (e.g., <careerCluster country="US" region="IL">[a given cluster name]</careerCluster>)
ISLE Extension
Not a part of Dublin Core, NSDL_DC, LOM, LRMI, LAR, or schema.org.
ISLE's focus is not solely K-12; the Career Cluster tag will be used with the STEM fields and other high-demand occupational fields for adults/professionals
The career cluster "Energy" is a career cluster local to Illinois; ISLE will be publishing this as a local rather than a Federal career cluster.
Federal career clusters will be published with a "Country" attribute of "US" and will lack a "Region" attribute. Local career clusters are published with a "Country" attribute of "US" and a "Region" attribute of "IL". ISLE will use USPS abbreviations for regions, so a career cluster local to Puerto Rico would be published with a "Country" attribute of "US" and a "Region" attribute of "PR", because Puerto Rico is a Commonwealth of the US.
ISLE understands all 16 Federal career clusters + one local cluster, "Energy".
