Metadata Harvesting Harvesting –in the OAI context, harvesting refers specifically to the gathering together of metadata from a number of distributed repositories into a combined data store OAI-PMH (OAI Protocol for Metadata Harvesting) –OAI-PMH is a harvesting protocol for sharing metadata between services.
12
Data Provider (Ex. Institutional repository) Maintain repository Expose metadata according to a metadata standard (e.g. DC) Register with OAI Service provider Register with OAI Extract metadata from registered repositories (‘harvest’) Provide services (e.g. central index) Interoperability through OAI-PMH Protocol * * http://www.openarchives.org/ IR-1IR-2
13
Harvesting Software To harvest metadata from the OAI- compliant repositories (data providers), a harvesting software is needed –PKP Harvester from SFU http://pkp.sfu.ca/harvester_download –Arc from ODU http://oaiarc.sourceforge.net/
