Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is 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 developed by the Open Archives Initiative.
Extrica Journals support the OAI Metadata Harvesting Protocol 2.0. Metadata for all published articles is available via the OAI-PMH interface to interested Service Providers.
Examples of OAI-PMH Requests
