Comprehensive Support for DLESE Metadata Collection Builders
This document outlines essential support resources and processes for collection builders contributing to the Digital Library for Earth System Education (DLESE). It covers terminology, metadata formats, collection accessioning, and maintenance strategies. Key topics include crosswalk procedures for metadata transformation, validation techniques, and online resources. Additionally, it emphasizes proactive approaches to collection development and quality assurance, ensuring robust participation in metadata management and adherence to standards. The document serves as a vital guide for enhancing the efficiency and effectiveness of contributions within the DLESE framework.

Talk Organizer • Terminology • Metadata formats used by collection builders • How to contribute a collection • Support specifics and examples • Support to Collections Accessioning Taskforce • Collection development issues
Terminology • Crosswalk - to change metadata formats • Transform - code that performs the crosswalk • OAI - harvesting method by the Open Archives Initiative - Protocol for Metadata Harvesting • Validation - verify required metadata & vocabs • Native metadata - the metadata format of a collection builder’s records before transformation to a DLESE metadata format
DLESE/ DPC Frameworks/ Formats • ADN - online and offline resources • DLESE-IMS - online resources only • Annotation - resource reviews, comments, connecting additional resource content • Collection - collection characteristics • News-Opps - announcements, conferences • Object - FAQ’s, glossary terms • SMS - Strand Map Service for AAAS benchmarks
Native Metadata Formats Used by Collection Builders • FGDC - data (government agencies) • IMS - learning objects • Onix - book publishers format • NSDL-DC - NSDL’s version of Dublin Core; ADN records are transformed to this for NSDL • Other Native- particular to each collection • DPC helps collection builders change their metadata to a DLESE metadata format
Contribute a Collection Process (1) • Determine if collection is within scope • Determine DLESE collection type and DLESE metadata format • Understand collection accessioning (adding) and deaccessioning (removing) • Determine membership for DRC • Create a collection scope statement
Contribute a Collection Process (2) • Determine DLESE required metadata fields • Create metadata records in the appropriate DLESE metadata format • Compile overarching collection information • Send metadata records to the DLESE Program Center (DPC) • support for sending to NSDL
Contribute a Collection Process (3) • Test the collection in DLESE systems • Obtain Collections Accessioning Taskforce approval to be a DLESE collection • Maintain the collection
Support & Maintenance Feedback • Provided at all steps in contribution process • Provided as maintenance after accessioning • Includes technical and non-technical issues • Done by: phone (40%); email (50%); face to face meetings (10%) • Received about 500 emails related to cataloging and collection support in 2003
Overarching Technical Support • Crosswalks to DLESE metadata formats (requires learning CB’s native metadata) • DLESE software training for the catalog system (DCS) and harvest system (OAI) • Database design (what information to capture) • Keep CB’s DLESE software upgraded • Create collection record for NSDL • Troubleshoot DLESE software installs & use
Technical Record Checks • URL links • Proper XML encoding • Syntax checks on email addresses • Duplication (on URLs and identification numbers) • Validation (has required metadata & vocabs) • Test in discovery system • Crosswalk records to NSDL format
Non-technical Support • Assist in writing scope statements • Assist in use of correct vocabularies • Provide examples of good descriptions • Suggest gathering or organizing strategies • Resource quality checks • Metadata quality checks • Catalog training • Explain policies and accessioning process
Collection Support Examples (1) • All records have the same URL or id number • Descriptions are cutoff in mid-sentence • Descriptions use 3 words or less • Every description is the same • Records use vocabs and required metadata but won’t index in the discovery system • Records don’t use controlled vocabularies & required metadata
Collection Support Examples (2) • Records use improper character encoding • 50% of the records have broken URLs • Records using almost every NSES standard • CB says go get new records but then there are no records to get • CB did not assign own record ids but rather used ids that already exist in DLESE • Metadata field is misinterpreted
Support to Collections Accessioning Taskforce • Records • Collection description • URL to scope statement • Summary of collection robustness in terms of metadata quality, link checking and resources • Provide the collection contact information • Stats of the collection (number of records, will it go on to NSDL, topics covered)
Collection Development Issues • Must now actively seek out collections • Must be very proactive to move collection builders through the contribution process • Must be very proactive with current collections in maintaining robustness (e.g. URLs) • Must propagate NSDL metadata changes down to DLESE collections
