1. ALCME: OAI at OCLC Jeffrey A. Young OCLC Online Computer Library Center, Inc.

2. Project community Networked Digital Library of Theses and Dissertations (NDLTD) project Develop open-source applications for the creation and maintenance of a distributed catalog of theses and dissertations (ETD) Visit http://www.ndltd.org/ and http://purl.org/alcme/ FOR MORE INFO...

3. Thesis Metadata Standard (TheMS) Dublin Core-based, with additional elements from new namespaces Resource Description Framework (RDF) based Incorporates linking to a distributed name authority database

4. NDLTD’s use of OAI Distribution mechanism for thesis and dissertation records Distribution mechanism for name authority metadata (proposed)

5. OAI alpha-test collection ETDCat: Thesis and dissertation records extracted from OCLC’s WorldCat database Currently, a 100,000 record subset in Dublin Core format (~2 million total) Eventually, will support NDLTD’s TheMS metadata format Visit http://purl.org/alcme/ FOR MORE INFO...

6. Technical infrastructure OAICat: an open-source OAI protocol implementation (Java Servlet web application) OAIHarvester: an open-source OAI harvester (Java application) Assuming there is a Java interface to your database engine, customization could be accomplished in a matter of a few hours

7. Technical infrastructure (related) Gwen/Pears: open-source database and search engine MARC to Dublin Core converter (http server based on the crosswalk used in OCLC’s CORC service) Extensible Open RDF (EOR): an open- source RDF toolkit (in development)

8. Design approach Open-source to avoid duplication of effort Modular design for ease of maintenance Use existing tools wherever possible, such as Java Servlets and XSLT Easy to deploy Easy to customize

9. Development challenges NDLTD’s TheMS format is based on the Resource Description Framework (RDF) NDLTD’s TheMS format expects a linking mechanism for name authority data

10. From here Clean and release the OAIHarvester software for others to use Prototype the NDLTD authority linking mechanism Add TheMS format support to the thesis and dissertation repository (ETDCat) Contact me at: jyoung@oclc.org FOR MORE INFO...
