Metadata Harvesting (OAI-PMH)
Metadata harvesting consists of both exposure and aggregation of metadata; that is, in order for it to be harvested, it must first be made available. Native schema is “OAI Dublin Core.”
In a metadata harvesting framework such as the OAI-PMH, there are two classes of resources:
- Data Providers, repositories that expose their collections' metadata
- Service Providers, services that harvest metadata from data providers, enabling users to search across discrete collections
