Open Archive Initiatives (OAI)

As an organization committed to the wider dissemination of knowledge, BNJ supports the OAI Metadata Harvesting Protocol (OAI-PMH Version 2.0).

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is used to govern the collection of metadata descriptions and enables other archives to access the BNJ database. The protocol has been developed by the Open Archives Initiative based on ensuring interoperability standards in order to ease and promote broader and more efficient dissemination of information within the scientific community.

As a Registered Data Provider, metadata for published articles are available via our interface at the base URL:
