|
Using metadata for theses and dissertations |
|
|
|
|
Networked Digital Library of Theses and
Dissertations |
|
Run out of Virginia Tech |
|
Some 100+ members interested in improving access |
|
OAI servers seem a natural direction |
|
|
|
|
|
|
Released a metadata standard |
|
EDTMS |
|
Dublin Core-like with own namespace |
|
Currently XML based |
|
RDF a possibility |
|
Incorporates linking to a distributed name
authority database |
|

Open Archives Initiative Metadata Harvesting
protocol (http://www.openarchives.org/OAI/openarchivesprotocol.htm) |
|
Allows efficient harvesting of metadata |
|
|
|
|
Make information widely available |
|
Allow layering of systems: |
|
|
|
|
|
Uses HTTP |
|
Fairly simple URLs to |
|
Identify the server |
|
List formats, record sets |
|
Get records (can specify date modified) |
|
Has flow control so that large sets can be
managed |
|
|
|
|
|
XML version of Dublin Core is required |
|
Other metadata formats possible (wrapped in XML) |
|
Typical uses: |
|
Publish metadata for a special collection |
|
Use to keep two catalogs synchronized |
|
|

|
Starting to embed services in the records |
|
Authority links |
|
OCLC Open Access links |
|
|
|
|
Harvesting a variety of OAI servers |
|
Making them available in a single catalog |
|
Most theses are already in WorldCat |
|
May be able to get more foreign theses |
|
|
|

|
Links into WorldCat information (planned) |
|
Associated searches |
|
Holdings |
|

New research project |
|
Advanced Collection Environment |
|
ASP model for managing collections |
|
Starting with personal collections |
|
Simplifies |
|
Allows more experimentation |
|
Expect much to cross over to libraries |
|
|
|
|
|
Dublin Core based |
|
First few hundred records are free |
|
Tries to be a complete service |
|
Targeted for the serious collector |
|
Emphasis on management, not commerce |
|
Expect testing within OCLC Research in October,
testing outside late this year |
