17 CIDOC 2000 Creating GEM Metadata

18 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.

19 CIDOC 2000

20 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

29 CIDOC 2000 Why use Metadata? Lack of precision in web searching Time-consuming for user to determine quality, authority

30 CIDOC 2000 Why use Metadata? Economics of traditional cataloging Internet resources move,disappear Users one click away from the resource

31 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.

32 CIDOC 2000 Why use Metadata? Customized interfaces to the same metadata catalog education.go.com

33 CIDOC 2000 Why use Metadata? Allows organizations to create own Gateways: CHIN (Canadian Heritage Information Network) MCI Marco Polo Project –6 partner sites

34 CIDOC 2000 Why use Metadata? National Institute for Literacy – LINCS –Network of adult literacy websites NASA –Office of Space Science –Distributed NASA educational materials
