iLumina Digital Libraryhttp://dl.uncw.edu

OLAC 2004 Montreal

iLumina Digital Library

• One of 356 collections of the National Science Digital Library (NSDL)

• Funded by the National Science Foundation Digital Library Initiative Phase II (NSF DLI-II)

• Features 1600 undergraduate teaching resources in science and mathematics

• Created with IMS-compliant metadata

OLAC 2004 Montreal

Project History

• Original iLumina project (2000-2003) funded to develop database & interfaces for searching and contributing resources

• Current iLumina project (2003-2005) funded to create a model for sustainability through integration with traditional library systems

OLAC 2004 Montreal

iLumina Goals

• Create a widely applicable model for sustaining NSDL collections beyond the period of their grant funding

• Develop a method for enhancing access to the digital resources contained in the collections

OLAC 2004 Montreal

Catalogers’ Role

• Analyzed and studied record fields in iLumina Digital Library

• Created sample MARC records for two records from iLumina

• Used sample records as model in creating crosswalks for harvesting metadata

OLAC 2004 Montreal

Cataloging Challenges

• iLumina record fields vs. MARC fields

--Fields not in local system load table

--Fields not indexed in local library system

--Lack of label for 5xx fields in MARC

• Limiting searches to iLumina

-- Location scoping

-- Advanced keyword search

• Determining publisher, distributor

OLAC 2004 Montreal

Metadata Scheme Crosswalks

• Two tracks for iLumina data:--Ending at NSDL--Going into local library and ending at WorldCat

• Three initial crosswalks considered before availability of Innovative XML Harvester

• Two final crosswalks created and used after understanding the functionality of the XML Harvester

OLAC 2004 Montreal

Crosswalks Continued

• Experimental crosswalks:IMS-DC-MARCIMS-MARC-DCIMS-MARC

• Final crosswalks:IMS-NSDL_DC (Qualified DC)IMS-MARC XML

OLAC 2004 Montreal

Innovative XML Harvester

• Converts XML data to MARC and provides mechanism for loading records

--DC (Unqualified) to MARC--MARC XML to MARC--Other XML schemes to MARC

• Processes XML data through OAI provider

OLAC 2004 Montreal

Harvesting

• Harvest1: Metadata converter converts iLumina records into NSDL_DC and MARC XML. OAI provider processes both data formats.

• Harvest 2: NSDL harvests NSDL_DC metadata through OAI provider

• Harvest 3: Library harvests MARC XML metadata through OAI provider, processes it through load table and loads it into library database

Metadata Harvesting

OLAC 2004 Montreal

Metadata: IMS to MARC

OLAC 2004 Montreal

Harvesting to Library

• Customize local library system load table

--270 field

• Review local library system index table

--024 indexed in ISN (I)

--516 indexed in keyword notes (w)

OLAC 2004 Montreal

Clean up and Enhancement

• Catalog librarians enhance harvested iLumina records in local library database

• Authority work--LC Subject Headings--Name authority

• Bibliographic quality control--Punctuation --Name order--Abbreviations --Capitalization--Constant data --Fixed fields

OLAC 2004 Montreal

Sending Records to WorldCat

• Import enhanced iLumina records from local library system into CatME

• Batch upload iLumina records file to OCLC WorldCat

OLAC 2004 Montreal

iLumina’s Future

• Integration of submission, review, & cataloging processes within library

• Determination of usage trends by monitoring library holdings added to iLumina records in WorldCat

• Implementation of plans to increase size of the collection

• Creation of model for sustainability through documentation of the integration process

OLAC 2004 Montreal

Teamwork & Cultural Differences

• Team of scientists and librarians• Scientists unfamiliar with bibliographic

standards and conventions• Librarians unfamiliar with NSF/NSDL

environment• Ambiguous meanings of terminology:

“library,” “cataloging,” “metadata”• Librarians learning new XML/OAI applications

OLAC 2004 Montreal

Implications

• Sustainability is an important challenge for digital collections

• Integrating digital collections into an established university library catalog is a feasible model

• Non-librarians will be increasingly involved in creating digital collections

• Catalog librarians can provide expertise in bibliographic standards and conventions
