Workshop Goals
What is metadata and why is it important?
Become familiar with the DLESE metadata structure
Introduction to cataloging tool and best practices
3
Metadata for DLESE“Data about data” in the library will help teachers & learners find what they need
Characterizing and finding resources.What is it about? Who created it? Where do I find it? What do I need to use it? etc….
Information returned to user in search
Information shared with other libraries
The metadata record is what DLESE creates and holds, not the physical files of each resource.
4
Who Will Create DLESE Metadata?
DPC Staff as component of development
Collections groups of which WES is one
Community at large
You!

IMS Metadata Standard
The DLESE metadata framework is based on the IMS metadata standard because it :
Describes educational learning objects
Permits multiple levels of granularity
Supports extensibility to allow for specific DLESE community requirements
Allows for both controlled vocabularies and free text fields
Uses XML bindings for portable data exchange in both content and structure

Metadata in XML

DLESE-Specific Metadata
Scientific characterization• Earth science
taxonomies/vocabularies
• Geographic and temporal coverage - footprint
– By latitude & longitude– By name (with gazetteer)
Educational attributes • Learning resource type,
grade level…
8
DLESE-Specific Metadata:Community requests
Indicate level of peer review and classroom testing
Reference related resources (e.g. evaluation reports, other exercises or labs)
Include instructor comments as annotations
National Science and Geography standards
9
Controlled Vocabularies
Standardized vocabularies to facilitate search and retrieval, browsing classifications.
DLESE vocabularies are compilations of existing vocabularies and DLESE-specific terminology:
Learning resource typeAudienceSubjectTechnical requirements
Still under development, opportunity for community collaboration.
10
Metadata LevelsRequired Metadata:
Minimal metadata set to to identify the resourceProvides some descriptive, educational and computer information as well as subject assignment for browsing and assessment. All resources would include this information
Recommended Metadata:All of the required metadata plus more fields that make the resource searchable both spatially and temporallyProvides more technical, educational, and descriptive information for searching
Robust Metadata:Includes required, recommended fields plus all other fields. Allows for DLESE community specific searches
11
Metadata Fields for the Levels: Required
Required Metadata: URL, title, descriptionSubjectResource type, AudienceTechnical requirementsResource creator and cataloger informationCost, copyright
12
Metadata Fields for the Levels:Recommended and Robust
Recommended Metadata: Includes coverage, keywords, more educational and technical information
Robust Metadata:Includes the National Science Education Standards, peer review, related resources, annotations and difficulty by grade level
13
Cataloging Resources
Make informed decisions about content, pedagogy, and computer requirements based on best practices and cataloger expertise
From experience, spend 30 to 60 minutes to generate required metadata for unfamiliar resources
Manually catalog by copying, pasting, and typing while reviewing resource on-line
14
Become Familiar with Resource
Decide what to catalog and how (granularity)Create single records for resources as a whole
Create additional records if individual parts of resource differ substantially in technical requirements, descriptions and educational data
Create relationships between resources using the fields of description, learning resource type and relation
Strikes a balance between supporting resource discovery with reasonable user effort yet avoids potential user frustration with retrieving to many redundant records
Community developed collections may have varying levels of granularity

DLESE Resource Cataloger

Scope Statement
The scope of the DLESE collection is Earth system education, with particular emphasis on interdisciplinary areas. The collection seeks resources that bring the Earth System into the classroom or other learning site, and which demonstrate the application of science to solving real world problems. The collection shall favor resources which convey linkages and connections: the general with the specific, observation with interpretation, theory with application, global with local. The collection shall favor materials that are well-documented, easy to use, bug-free, motivational for learners, pedagogically effective, scientifically accurate,and which foster mastery of significant understandings or skills.

What Happens After I Submit My Record?
Record is reviewed for QA/QCInternal inventory controls assigned ( ID numbers, etc )Additional information added via XML“Ingested” into the databaseAvailable via the discovery systemTiming……will depend on volume of use
18
Future Metadata Development Plans
DLESE Resource Cataloger extended to recommended and robust metadata…. Standards, coverage
Continue controlled vocabulary refinement
Vocabulary definitions for all
Additional educational features; e.g. pedagogy, diversity, concept map connections
