Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH)


OAI-PMH provides a standard way for a data repository to expose metadata to third party indexing engines.  It serves as a low-barrier mechanism for repository interoperability.

Data Providers are repositories that expose structured metadata via OAI-PMH. Service Providers then make OAI-PMH service requests to harvest that metadata. OAI-PMH is a set of six verbs or services that are invoked within HTTP.
