1. DSpace & OAI-ORE: Object Reuse and Exchange

2. Pros and Cons Pros: One need not send metadata & Digital Object by CD
One can have their own IR
Central agency like INFLIBNET
can automatically collect digital objects from Universities. Least effort for INFLIBNET
Can leave out collections other than ETD of a University IR (selective Harvesting).

3. Pros Some Universities may not have Infrastructure to host an IR
IR sites warrant least downtime and maintainance requires expertise and expense

4. Each University has to change metadata schema to suit ETD or UKETD
Cons
Each University has to change metadata schema to suit ETD or UKETD

5. Object Reuse and Exchange OAI-ORE
OAI-PMH: Allows metadata to be harvested
OAI-ORE: Allows metadata & bitstreams
(digital objects) to be harvested

6. Two Sides of ORE Data Provider should enable OAI-ORE
Service Provider should be OAI-ORE compliant
One can make DSpace repository both a Data Provider and also a service provider

7. Enabling DSpace as ORE data provider
XMLUI should be enabled
(Older versions may not have XMLUI interface)
E.g.:
Should not be running on https

8. dspace.cfg dspace.baseUrl = http://drtc.isibang.ac.in
dspace.url = ${dspace.baseUrl}/xmlui
NOTE: it should not be localhost

9. Oaicat.properties (optional)
Enable Qualified Dublin Core
Crosswalks.qdc=org.dspace.app.oai.PluginCrosswalk
This allows metadata to be harvested using
QDC schema
One can always harvest simple DC (default) or
Intermediate metadata

10. Oaicat.properties (Optional modification)
You may enable following metadata schema to provide your metadata to others
DC QDC UKETD METS
MODS DIDL RDF MARC
DIM
NOTE: DSpace harvester uses only DC, QDC and Intermediate Metadata Format

11. Oaicat.properties (Optional modification)
Identify.repositoryName=LDL

12. config/modules/oai.cfg dspace.oai.url = http://drtc.isibang.ac.in/oai
There are lots of options that can be enabled or ignored

13. Testing What metadata Schema offered?
Syntax:
Example:
NOTE: You should see both “ore” and “qdc”.
Be aware of Camel Back Notation in oai verbs

15. Does ORE gets data?
Syntax:
Examples:

17. Does XMLUI Supports ORE?
Syntax:
Example:

19. If all tests are successful, we can assume the repository is OAI-ORE based data provider
The digital objects can be legally imported to your own repository along with the metadata
One can perform these tests on any repository
Each university repository should enable ORE and test

20. How to Harvest Digital Objects
Use XMLUI
Create/Edit Collection
Click on “Content Source”
This is a standard DSpace collection
This collection harvests its content from
an external source

23. Alternative How to Steal ?
If ORE is not enabled?
Screen Scrap full-record by using 'wget'
You can use jspui or xmlui side
Ignore the pages “If they do not contain dc.title
as they can be community/collection pages
