Stepping Up to LAR
Support contextualized learning experiences,
allowing users to find, use or deliver just the right digital content
2Slide3
LAR Activity Results
Both resources and metadata need quality improvements
NSDL resources are showing their ageNSDL metadata is missing a lot of basic information to support LAR
3Slide4
Approaches
Programmatic
: systems & services already operating on resources/metadata to move the NSDL towards LARManual: human-mediated processes already acting on the resources/metadata to move the NSDL towards LAR
Brainstorms
: other ideas (programmatic or manual) to move the NSDL towards LAR
4Slide5
Programmatic Approaches
Metadata normalization
: values standardized or may not be used (e.g. term zero for audience)Search Filtering: records missing title, URL or description are removed (bad values remain)
Native Metadata
: other formats accepted; need to convert to
nsdl_dc
to see at NSDL.org
Contextualization
: usage data (
comm_para
) & annotations (
comm_anno
) accepted
5Slide6
Manual Approaches
NSDL Accessioning Board (NAB)
: approves new & deaccessioned resource collections2009 Collections Refocus
: keep library content that supports educational learning by removing 2.1 million items
Initial LAR
Catergorization
: judge LAR of a collection: most ready, could be ready, no hope or not applicable
6Slide7
Brainstorms
Metadata Quality Guidelines (like Resource and a goal of this workshop)
: concise explanation of metadata values & quality for desired fieldsLAR specific metadata framework :
a programmatic means to require metadata like education level or resource type to be present in order to create a valid
XML record
Weeding for LAR
: Like 2009 but apply LAR concepts; encourage smaller & more targeted
collections (
