DLESE & ADEPT: A CollaborationADN metadata framework
Cataloging system for creation and management of metadata records
Footprint specification tool
Gazetteer development & services
Middleware use
4
ADN Metadata FrameworkADEPT/DLESE/NASA’s Joined Digital Lib.
A common XML-schema based framework
Co-development of framework componentsgeospatial, collection, review, models
Describe geoscience educational learning objects, including georeferenced objects
Looks like a hybrid of IMS and DC but with specific community-driven fields.

DLESE Catalog SystemStructure: Acts on XML files in a flat directory structure (no database)
Assumption: unique mapping between library ID and URLs
Underlying Indexes:Metadata index over editable fields onlyResource content index over “reachable” resources
Technical Specification:IE 4.x or higher, Netscape: 6.0,Lucene 1.0, Tomcat 3.2, Java 1.3, JDOM Beta 4
8
What Can the System Do?Contribute: create new metadata records
Discover: controlled vocabularies & keyword searches on metadata records in the library, plus search resource content when available
Manage: review & edit; keyword & fielded search, some controlled vocabulary search; plus movement through QA process
Share: import/export metadata records to/from other XML-based collections via an OAI service (not yet implemented)

Types of Searches Over Metadata
Metadata Index
Search Manage Discover
1. Keyword Over any editable field (includes URL, org)geology:448
Over only description, title, topic, resource type & grade levelgeology: 415
2. Controlled Vocabulary
Partially implemented over topic, resource type and grade level
Over topic, resource type & grade levelcheckbox geology:387
3. Fielded Over editable fields+topic:geology: 387

Tasks1. Find all records that Holly Devaul created.
2. Find all records that ADEPT has contributed.
3. Cataloger Goodman forgets her DLESE ID but knows her resource is about hurricanes.
4. Cataloger Tierney wants to create a relationship between records 943 & 946.
5. Catalog the SEES records with more granularity emphasizing ocean temperature.

Future System FeaturesVocabulary management
Produce collection reports
Manage the metadata framework
Manage multiple collections
Produce records in other formats
Automatic resource characterization
Link checking
