'Open Archives Initiative Protocol for Metadata Harvesting'. Part of discussion about open source geodata.

Description

  • Leightweight:
    • A low barrier interoperability specification
    • RESTful: HTTP based, GET / POST requests, XML responses
  • Clear concepts:
    • Based around metadata harvesting model (metadata aggregation and syndication)
    • Metadata about resources, mandates unqualified Dublin Core as default
    • Not a search protocol! That could be for example enhanced or merged versions of OpenSearch/GeoRSS and SRU/SRW besides WFS.
  • Extendable: Has extension mechanism for more domain specific metadata models
  • Stable: OAI has committed to making subsequent revisions of the protocol backwards compatible.
  • Established: Implemented - among others - by Google, CiteSeer and MSN as well as by dozens of open source tools, like OAICat (Java) or mod_oai (C, installed at 500 sites); see more tools in the Weblinks section below.

There are following alternatives (Remarks: all considered either inappropriate or not established or at least 'painfull' compared to OAI-PMH):

  • Z39.50 and SRW - the more leightweight and 'modern' successor of Z39.50
  • UDDI - the SOAP thing
  • WFS - the OGC thing
