1 DSpace & OAI-ORE: Object Reuse and Exchange
ARD Prasad DRTC, ISI Bangalore

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 =
dspace.url = ${dspace.baseUrl}/xmlui NOTE: it should not be localhost

9 (optional)
Enable Qualified Dublin Core This allows metadata to be harvested using QDC schema One can always harvest simple DC (default) or Intermediate metadata

10 (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 (Optional modification)

12 config/modules/oai.cfg dspace.oai.url =
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



26 Q? ThanQ
