Creating GEMMetadata

Creating GEM Metadata

• GEMCat Cataloging Module create individual
  metadata records.
• Database Collections write script/program/query
  to output GEM records
• Future researching the use of Natural Language
  Processing to automate metadata creation.

Creating GEM Metadata

• Database collections
• compare GEM elements with db fields
• write script/program/query to output GEM records
• test output with GEM technical systems
• Time few hours

Why use Metadata?

• Lack of precision in web searching
• Time-consuming for user to determine quality,
  authority

30
Why use Metadata?

• Economics of traditional cataloging
• Internet resources move,disappear
• Users one click away from the resource

31
Why use Metadata?

• Establishes a consistent means to search across
  websites while maintaining your autonomy
• Brings users to your site
• The Gateway searches 12,000 resources across 150
  websites.

32
Why use Metadata?

• Customized interfaces to the same metadata
  catalog
• www.thegateway.org
• www.nea.org/gem
• education.go.com
• www.teachers-connect.net/

33
Why use Metadata?

• Allows organizations to create own Gateways
• CHIN (Canadian Heritage Information Network)
• MCI Marco Polo Project
• 6 partner sites

34
Why use Metadata?

• National Institute for Literacy LINCS
• Network of adult literacy websites
• NASA Office of Space Science
• Distributed NASA educational materials

35
2000 Priorities

• Academic Standards
• Vocabulary Registries
• Higher and Adult Education
• Working Groups
• Continued growth - membership, content, users
