ARD Prasad DRTC, ISI Bangalore ard@drtc.isibang.ac.in DSpace & OAI-ORE:Object Reuse and Exchange
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). Pros and Cons
Some Universities may not have Infrastructure to host an IR IR sites warrant least downtime and maintainance requires expertise and expense Pros
Each University has to change metadata schema to suit ETD or UKETD Cons
OAI-PMH: Allows metadata to be harvested OAI-ORE: Allows metadata & bitstreams (digital objects) to be harvested Object Reuse and ExchangeOAI-ORE
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
XMLUI should be enabled (Older versions may not have XMLUI interface) E.g.: http://drtc.isibang.ac.in/xmlui Should not be running on https Enabling DSpace as ORE data provider
dspace.baseUrl = http://drtc.isibang.ac.in dspace.url = ${dspace.baseUrl}/xmlui NOTE: it should not be localhost dspace.cfg
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 Oaicat.properties(optional)
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 Oaicat.properties(Optional modification)
Identify.repositoryName=LDL Identify.adminEmail=ard@drtc.isibang.ac.in Oaicat.properties(Optional modification)
dspace.oai.url = http://drtc.isibang.ac.in/oai There are lots of options that can be enabled or ignored config/modules/oai.cfg
Syntax: http://[full-URL-to-OAI-PMH]/request?verb=ListMetadataFormats Example: http://drtc.isibang.ac.in/oai/request?verb=ListMetadataFormats NOTE: You should see both “ore” and “qdc”. Be aware of Camel Back Notation in oai verbs TestingWhat metadata Schema offered?
Syntax: http://[full-URL-to-OAI-PMH]/request?verb=ListRecords&metadataPrefix=ore Examples: http://drtc.isibang.ac.in/oai/request?verb=ListRecords&metadataPrefix=ore Does ORE gets data?
Syntax: http://URL_of_DL/xmlui/metadata/handle/HANDLE_NO/ITEM_NO/ore.xml Example: http://drtc.isibang.ac.in/xmlui/metadata/handle/1849/8/ore.xml Does XMLUI Supports ORE?
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
Use XMLUI Create/Edit Collection Click on “Content Source” This is a standard DSpace collection This collection harvests its content from an external source How to Harvest Digital Objects
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 AlternativeHow to Steal ?
