'Open Archives Initiative Protocol for Metadata Harvesting'.
Description
- A low barrier interoperability specification
- Based around metadata harvesting model
- Metadata about resources
- HTTP based
- GET / POST requests
- XML responses
- Uses unqualified Dublin Core
- Stable (OAI has committed to making subsequent revisions of the protocol backwards compatible)
- Not a search protocol - that could be for example enhanced or merged versions of OpenSearch/GeoRSS and SRU/SRW besides WFS.
