Creating GEM Metadata

Creating GEM Metadata: 

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: 

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

Meta-data: 

Meta-data <meta name="DC.package.begin" content="1"> <meta name="DC.title" content="(lang=en)Dancing Spaghetti"> <meta name="DC.format" content="(scheme=IMT)(type=contentType)text/HTML"> <meta name="GroupStart" content="1"> <meta name="DC.publisher" content="(type=role)onlineProvider"> <meta name="DC.publisher" content="(type=name)The Science House"> <meta name="DC.publisher" content="(type=homePage)http://www.ncsu.edu/science_house"> <meta name="GroupEnd" content="1"> <meta name="DC.type" content="(scheme=GEM)Activity"> <meta name="GroupStart" content="2"> <meta name="DC.subject" content="(scheme=GEM)(type=levelOne)Science"> <meta name="DC.subject" content="(scheme=GEM)(type=levelTwo)Chemistry"> <meta name="GroupEnd" content="2"> <meta name="DC.date" content="(scheme=ISO8601:1988)(type=recordCreated)1999-06-28T04:08:31-5:00"> <meta name="DC.description" content="Spaghetti is more dense than water but when placed in a solution of baking soda and vinegar&#044; the carbon dioxide gas that is released adheres to the spaghetti causing it to rise to the surface.

Why use Metadata?: 

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

Why use Metadata?: 

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

Why use Metadata?: 

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.

Why use Metadata?: 

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

Why use Metadata?: 

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

Why use Metadata?: 

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

2000 Priorities: 

2000 Priorities Academic Standards Vocabulary Registries Higher and Adult Education Working Groups Continued growth - membership, content, users
