Creating GEMMetadata

CIDOC 2000

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.

Why use Metadata?

• Lack of precision in web searching

• Time-consuming for user to determine quality, authority

CIDOC 2000

Why use Metadata?

Economics of traditional cataloging

• Internet resources move,disappear

• Users “one click away” from the resource

CIDOC 2000

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.

CIDOC 2000

Why use Metadata?

Customized interfaces to the same metadata catalog

Allows organizations to create own “Gateways”:

• CHIN (Canadian Heritage Information Network)

• MCI Marco Polo Project

– 6 partner sites

CIDOC 2000

Why use Metadata?

• National Institute for Literacy – LINCS– Network of adult literacy websites

• NASA –Office of Space Science– Distributed NASA educational

materials
